Changelog

API Reference & Referrals Page Refresh

The API reference and referrals pages have been rebuilt to match the v1.17.0 design refresh, the deployment, volume, and reserved GPU wizards have picked up another round of polish, and Spheron AI spot offers now stay fresher in the marketplace.

• New API Reference Page: Endpoints are now grouped by category, with short descriptions, cleaner endpoint cards, refreshed request and response examples, and a tighter quick-test panel for easier scanning and testing
• Refreshed Referrals Page: Stats, the share link, share buttons, and the "how it works" section have been rebuilt with clearer hierarchy, step cards, and reward callouts, so it is easier to see your rewards and pass on your link
• More Wizard Polish: The deployment, volume, and reserved GPU wizards have picked up another round of spacing and typography tweaks across cards, selections, and order summaries

• Fresher Spheron AI Spot Pricing: Spheron AI spot offers now refresh on the same fast cadence as other spot providers, so spot availability and pricing stay current without a manual reload

Marketplace Design Refresh, Volume Discounts & NVLink GPU Flagging

A top-to-bottom visual refresh across billing, teams, volumes, API keys, SSH keys, deployment, and reserved GPU pages. Discounts now apply to volumes the same way they apply to deployments, the reserved GPU contact form captures more useful detail, and Spheron AI NVLink GPUs are clearly flagged in the marketplace.

• Unified Visual Language: Billing, teams, volumes, API keys, SSH keys, deployment wizard, and reserved GPU wizard have all been redesigned around a shared header, card, and table style for a calmer, more consistent look
• New Team Switcher: The team menu has been consolidated into a single switcher in the top navigation. Create, switch, and manage teams from one place instead of several disconnected dialogs
• Refreshed Billing Page: Balance, deposit history, usage analytics, discount overview, and the add-credits flow (custom amount, saved card, billing details) have all been rebuilt with clearer hierarchy and tighter spacing
• Smoother Wizards: Deployment, volume, and reserved GPU wizards share a common header treatment and improved step layouts. The order summary sidebar now stays put when dropdowns or dialogs open, so it no longer disappears mid-configuration
• API Keys & SSH Keys: Empty states, generation dialogs, the whitelist-required state, the quick reference, and the documentation card have all been updated to match the new style
• Volume Cards & Sidebar: Volume cards, the volume details sidebar, the resize dialog, and the create-volume order summary have been refreshed to read more clearly at a glance

• Volume Discounts: Active team discounts now apply to volume hourly rates at creation and at resize time, the same way they already apply to deployments. The discounted rate is locked in when the volume is created. If a team's discount later expires or is revoked, the volume automatically reverts to its standard rate on the next billing cycle
• Spheron AI NVLink GPUs Flagged: Spheron AI GPU offers that are NVLink-bridged variants (for example H100 NVL) are now clearly marked in the marketplace so you can pick the interconnect that matches your workload
• Richer Reserved GPU Contact Form: The reserved GPU request form now captures phone country and country code separately (with a country picker), preferred GPU model, requested GPU quantity, and an optional marketing consent, so the team can route inquiries faster

• Discount Preview No Longer Fails Silently: The discount-code preview used in billing, the deposit flow, and the deployment and volume wizards now handles non-JSON error responses gracefully instead of failing in the background. Users see a clear error state instead of a stuck preview
• Create Team Dialog Stays Open Until Done: The create team dialog now stays open and shows its loading state until the team is actually created, matching the behavior of the invite member and add SSH key dialogs
• Data Crunch Cleanup Safety: The background cleanup that removes orphaned Data Crunch volumes now has additional safeguards so marketplace-tracked, idle, and shared user-owned volumes are never eligible. Only true orphans can be removed
• Runtime Display: Reserved runtime hours now display as N/A instead of N.A when no expiry is set

• Volume Hourly Rate (all clients): Volumes created or resized while a team has an active discount now bill at the discounted rate. The volume response from GET /api/volumes and GET /api/volumes/:volumeId reflects the locked-in discounted rate; the pre-discount rate is also returned for reference. If the team's discount later expires, the rate automatically reverts on the next billing cycle. No request changes are required for clients to benefit from this; pricing endpoints continue to return public list rates.

• Spheron AI GPU Offers: GPU offers from Spheron AI now include an nvlink: true flag in their metadata when the GPU model is an NVLink-bridged variant (for example H100 NVL, A100 NVL). Non-NVLink offers do not include the flag. Existing fields are unchanged, so existing integrations continue to work and can opt in to the new flag when ready.

Spheron AI Persistent Volumes & Provider Rules Dialogs

Persistent storage, now on Spheron AI. Create a volume, attach it to a GPU instance at deploy time or while it's running, and move it between instances without losing data. Every volume provider now has a dedicated rules dialog so you know exactly how attachment and lifecycle work before you commit.

• Spheron AI Volumes: Spheron AI is now a supported volume provider. Create and manage persistent storage from the /volumes dashboard, backed by Cloud-SSD storage
• Attach at Deploy Time or Later: Pick a Spheron AI volume in the deployment wizard, or attach one to an already-running instance from the volume or instance sidebar. No need to tear down and redeploy to add storage
• Hot-Detach Supported: Detach a volume from a running instance and reattach it to a different instance without terminating either one. Your data moves with it
• Up to 10 Volumes per Instance: A single Spheron AI instance can have up to 10 volumes attached at once. The UI and API enforce the limit automatically so attach requests fail fast instead of in the middle of a deploy
• Single-Attach Volumes: Each Spheron AI volume can only be attached to one instance at a time. The dashboard hides incompatible volumes in the deploy wizard and shows a clear error if you try to double-attach
• Persistent After Termination: Volumes survive instance termination by default. Delete them explicitly from the dashboard when you're done
• Large Storage Ceiling: Create volumes from 1 GB up to 40 TB in a single volume
• Data Crunch Multi-Volume Support: Data Crunch instances can now attach up to 10 shared volumes at a time, up from a single volume in v1.14.1. Each Data Crunch volume can still be mounted on multiple instances concurrently, so you can fan out shared data and mix storage pools on the same instance

• Provider Rules Dialogs: Every volume provider (Spheron AI, Data Crunch, Sesterce, Voltage Park) now has its own "Volume Rules" dialog accessible from the create-volume and attach flows. Each dialog spells out per-provider limits: attach timing, concurrent-attach rules, resize policy, and lifecycle behavior, so you know what you're getting before you create a volume
• Volume Created Success Modal: After a Spheron AI volume is created, a confirmation modal summarizes the rules and offers a one-click "Deploy GPU" shortcut to go straight into the deployment wizard with the new volume pre-selected
• GPU Offer Availability Warning: The create-volume wizard now checks whether the selected provider and region actually have live GPU offers. If there's nothing to attach the volume to, a warning surfaces in the order summary before you confirm
• Smarter Volume Matching in Deploy Wizard: The attach step in the deployment wizard now respects per-provider constraints. Incompatible volumes are filtered, limit warnings appear when you hit the cap, and single-attach volumes already bound elsewhere are shown as blocked with an explanation
• Smarter Region Default on Create Volume: The create volume wizard now auto-selects the first region that actually has live GPU offers instead of blindly picking the alphabetical first. Regions without GPU offers are clearly labeled "No GPU offer present" in the Sesterce, Data Crunch, and Spheron AI dropdowns so you can see which ones to avoid before selecting. The Data Crunch dropdown is also cleaner, with decorative flag graphics removed
• Consistent Region Name Formatting: Massed Compute regions (for example us-central-3) now display as "Us Central 3" in the deployment wizard, order summary, and instance cards, matching the style used for Sesterce and Spheron AI

• No In-Place Resize (Enforced): Spheron AI volumes cannot be resized once created. The API now returns a clear error on resize attempts instead of silently succeeding. To grow storage, create a new larger volume and migrate your data
• Accurate Region Codes in UI: The dashboard now shows clean region codes (for example CANADA-1) regardless of the provider's internal naming
• Stale Deployments No Longer Lock Volumes: If a previous instance terminated without a clean detach, single-attach volumes are no longer permanently locked. Attach attempts skip terminated, failed, stopped, and deleted deployments when checking occupancy, so you can always reclaim the volume onto a new instance. Applies to both Spheron AI and Voltage Park volumes
• Cleaner Single-Attach Error Messages: When a single attach volume is genuinely in use, the error message now lists only the live conflicting instances instead of every instance the volume has ever been attached to. Terminated and failed deployments no longer clutter the list
• Voltage Park Single-Attach Enforced Server-Side: Voltage Park's one-volume-per-instance and one-instance-per-volume rules are now enforced by the API, not just the UI. Double-attach attempts are rejected even when the request bypasses the dashboard

Creating and using a Spheron AI volume involves three steps:

1. Fetch available regions: GET /api/volumes/regions?provider=spheron-ai returns a regions array. Each entry has an id (the region code to pass at creation time) and a name. Each region now also includes a hasGpuOffers boolean so you can check availability before creating a volume in a dead region.

2. Create the volume: POST /api/volumes with provider: "spheron-ai", region: "<region id from step 1>", name (max 50 characters), and sizeInGb (1–40960). The response includes the volume id you will use for all subsequent operations.

3. Attach to an instance: two options depending on your workflow:

   • At deploy time: include volumeIds: ["<volumeId>"] in your POST /api/deployments request
   • After the instance is running: POST /api/volumes/{volumeId}/attach with { "deploymentId": "<id>" }

Detaching and re-attaching: POST /api/volumes/{volumeId}/detach with { "deploymentId": "<id>" } frees the volume to be attached elsewhere. Data is preserved. Detach and re-attach are supported without instance downtime.

Limits: Each Spheron AI instance supports up to 10 attached volumes. Each volume can be attached to only one instance at a time. Resize is not supported. Rename is not supported, so pick the name you want at creation.

Pricing: GET /api/volumes/pricing?provider=spheron-ai returns the current hourly rate per GB so you can estimate cost before creating a volume.

Data Crunch limits (updated): Each Data Crunch instance now supports up to 10 attached volumes (was 1 in v1.14.1). Multi-instance attach is unchanged. A single Data Crunch volume can still be mounted on many instances at the same time.

API Docs correction: The API reference now uses CLUSTER as the instanceType for multi-node deployments, matching the v1.10.0 rename. Any request examples that still showed BARE_METAL have been updated.

Sesterce Persistent Volume Support

Persistent storage is now available on Sesterce. Create volumes, pick your cloud provider and region, and attach them to instances at deploy time. Your data outlives any single session.

• Sesterce Volumes: Sesterce is now a supported volume provider. Create and manage persistent storage volumes from the /volumes dashboard
• Cloud Provider + Region Picker: When creating a Sesterce volume, choose your cloud provider and region from a dynamic dropdown so volumes are always deployed where your compute is
• Deploy-time Attachment: Select a compatible Sesterce volume in the deployment wizard. It attaches automatically when the instance starts, no extra steps needed
• Automatic Compatibility Filtering: The deployment wizard only shows volumes that match the region and cloud provider of your selected GPU offer. No risk of picking an incompatible volume
• Volume Deletion: Delete a Sesterce volume from the dashboard once the instance it was attached to has been terminated

Creating and using a Sesterce volume involves three steps:

1. Fetch available cloud providers and regions: GET /api/volumes/regions?provider=sesterce returns a regions array where each entry has an id (the region code), a name, a cloudId, and a cloudName. You need both id and cloudId when creating the volume. They must match the cloud provider and region of the instance you plan to deploy.

2. Create the volume: POST /api/volumes with provider: "sesterce", region: "<id from step 1>", cloudId: "<cloudId from step 1>", name, and sizeInGb. The response includes the volume id you will use when deploying.

3. Attach at deploy time: include volumeIds: ["<volumeId>"] in your POST /api/deployments request. The volume attaches when the instance is created. Post-creation attach and detach are not supported for Sesterce. The volume is bound at launch.

Compatibility: the cloudId and region of your volume must match the cloud provider and region of your GPU offer. Use GET /api/gpu-offers to find offers and cross-reference the region before creating a volume.

Pricing: GET /api/volumes/pricing?provider=sesterce with optional cloudId and region query params returns the current hourly rate per GB for that specific location.

Spheron AI: Open All Inbound Ports by Default

All ports are open out of the box. Spheron AI provider VMs now have full inbound access (TCP/UDP/ICMP, ports 1–65535, IPv4 and IPv6) applied automatically at creation time, with no manual firewall configuration required.

• Security rules at creation: Six inbound rules (TCP 1–65535, UDP 1–65535, and ICMP for both IPv4 and IPv6) are now passed directly in the VM creation payload via the security_rules field, replacing the previous post-creation polling approach
• Removed background firewall task: Eliminated the enableSSHFirewallWhenActive polling loop (up to 10-minute wait) and the separate enableSSHFirewall method that made individual POST /sg-rules calls after the VM reached ACTIVE state
• No more sshFirewallError tracking: Removed the sshFirewallErrorMap, the sshFirewallError field on VMInstance, and all related error-surface logic. Firewall setup is now atomic with VM creation

GPU Count Validation Hardening

Stricter GPU count validation. Deployment requests with a mismatched GPU count are now rejected reliably regardless of whether the value arrives as a string or a number, and validation errors are propagated correctly through the error-handling pipeline.

• Type-safe GPU count comparison: The GPU count check now coerces both the requested value and the offer config value to Number before comparing, preventing false validation failures caused by string/number type mismatches (e.g., "2" vs 2)
• GpuValidationError class: Introduced a dedicated GpuValidationError subclass so that GPU validation errors are identified with instanceof rather than fragile error.message.startsWith(...) string matching, eliminating the risk of silently swallowing errors or misclassifying HTTP status codes if the message text changes
• Route-level fix: deployment.routes.ts now uses instanceof GpuValidationError to classify the error as an HTTP 400, replacing the previous error.message.includes('Invalid GPU count:') check

Feature Announcement Modal & Sidebar Changelog Link

Stay up to date without leaving the dashboard. A new in-app feature announcement modal greets users with what's new since their last visit, and the sidebar now links directly to the changelog.

• Feature Announcement Modal: Automatically shows authenticated users any features released since their last visit. Slides through announcements newest-first with story-style progress bars, smooth slide transitions, and a 25-second auto-advance timer
• Per-User Tracking: Last-seen feature is persisted. The modal only re-appears when genuinely new features have shipped
• Learn More Links: Each announcement card links directly to the relevant docs or changelog section
• Changelog Sidebar Link: A compact "Changelog" entry with a "New" badge now lives in the sidebar bottom dock alongside the API Docs link, opening docs.spheron.network/changelog in a new tab

Sesterce Deployment Reliability Fix

Sesterce deployments no longer fail on name collisions. A 409 Conflict error that occurred when instance names clashed is now handled automatically with a unique suffix and retry logic.

• 409 Name Collision: Sesterce's /gpu-cloud/instances API rejects duplicate instance names with a 409. Deployment names are now suffixed with a random 6-character hex string (crypto.randomBytes(3).toString('hex')) to prevent collisions
• Retry Logic: If a 409 still occurs (e.g. extremely unlikely suffix collision), the deployment automatically retries with a freshly generated name, up to 3 attempts before failing
• Status Code on Errors: makeAuthenticatedRequest now attaches statusCode to thrown errors, enabling reliable detection of 409 vs other failure types
• SSH Key Cleanup: If all retry attempts are exhausted, any provisioned temporary SSH key is deleted to prevent resource leaks

TensorDock Deployment Fix & Improved Error Reporting

TensorDock deployments now work reliably. A 400 Bad Request error that blocked all TensorDock deployments has been fixed, and deployment failures now show human-readable error messages in the dashboard.

• TensorDock 400 Error: Removed an incorrect JSON
  wrapper (data.attributes) that was wrapping the request payload. TensorDock's API v2 expects a flat JSON body
• Field Name Casing: Renamed useDedicatedIp (camelCase) → use_dedicated_ip (snake_case) to match TensorDock's API contract
• Cloud-Init Format: Converted cloud_init from a JSON object to a YAML string, consistent with how other providers (e.g. Spheron AI provider) handle startup scripts

• Human-Readable Failure Reasons: TensorDock JSON error responses are now parsed and classified into user-friendly categories (e.g. "Insufficient resources", "Invalid configuration") stored as failureReason on the deployment
• Failure Details in Sidebar: InstanceDetailsSidebar now surfaces failureReason and failureDetails so users can see exactly why a deployment failed without digging through logs

Data Crunch Shared Volume Support

Shared NFS volumes on Data Crunch. Create persistent NFS-backed volumes, attach them to multiple instances simultaneously, and keep your data safe after instance termination.

• Data Crunch Volumes: Data Crunch is now a supported volume provider. Create and manage shared NFS volumes from the dashboard or via the API
• Multi-Instance Attachment: A single Data Crunch volume can be attached to multiple GPU instances at the same time, unlike Voltage Park which restricts each volume to one instance
• Region Selection: Deploy volumes into FIN-01 (Finland 1), FIN-02 (Finland 2), or FIN-03 (Finland 3). Each volume is pinned to the region you pick at creation time

• Persistent Volumes: Data Crunch volumes survive instance termination by default. Only deleted on explicit user action
• One Volume Per Instance: Each Data Crunch instance supports at most one shared volume at a time, though that same volume can be attached to unlimited instances concurrently

Creating and using a Data Crunch volume involves three steps:

1. Fetch available regions: GET /api/volumes/regions?provider=datacrunch returns a regions array where each entry has an id (the region code to pass at creation time), a human-readable name, and a country_code. Use the id value as the region field when creating the volume.

2. Create the volume: POST /api/volumes with provider: "datacrunch", region: "<region id from step 1>", name, and sizeInGb. The response includes the volume id you will use for all subsequent operations.

3. Attach to an instance: two options depending on your workflow:

   • At deploy time: include volumeIds: ["<volumeId>"] in your POST /api/deployments request
   • After the instance is running: POST /api/volumes/{volumeId}/attach with { "deploymentId": "<id>" }

After attachment, GET /api/volumes/{volumeId} returns the NFS mount command and mount path in the response. Copy these directly into your instance to mount the volume.

Detaching and re-attaching: POST /api/volumes/{volumeId}/detach with { "deploymentId": "<id>" } frees the volume to be attached elsewhere. Data is preserved.

Pricing: GET /api/volumes/pricing?provider=datacrunch returns the current hourly rate per GB so you can estimate cost before creating a volume.

New GPU Provider: Europe & North America Regions

More GPUs, more regions. A new provider is now available on the Spheron AI marketplace, adding H200, H100, A100, L40S, A6000, and A4000 inventory across Canada, Norway, and the US.

• GPU Models: H200 SXM, H100 SXM5 / NVL / PCIe, A100 SXM4 / NVL / PCIe, L40S, L40, A6000, RTX Pro 6000, A4000
• Regions: Canada (Montreal), Norway (Bergen), United States
• On-Demand & Spot: Both instance types are available. Spot instances offer the same GPU configurations at a lower price with no uptime guarantee

• Startup Scripts: Cloud-init startup scripts are supported. Packages, run commands, and file writes all work on this provider the same as others
• OS Options: 11 OS images to choose from, including Ubuntu 22.04/24.04, AlmaLinux 9, Debian 12, and CUDA-enabled variants (R535, R550, R570). Defaults to Ubuntu Server 22.04 LTS with CUDA 12.8 and Docker
• SSH Access: Port 22 is automatically opened on every new instance. No manual firewall configuration needed

Password Complexity Enforcement on Signup

Stronger account security. Signup now enforces password complexity rules before any Firebase call, giving users immediate, clear feedback.

• Weak Password Allowed: The signup form previously accepted any non-empty string as a password, including the user's own email address. This is now blocked
• No Complexity Checks: Passwords with no uppercase, no lowercase, or no digits were accepted without warning. All three are now required

• Minimum 8 characters
• Cannot be identical to your full email address (case-insensitive)
• Cannot be identical to the local part of your email (the portion before @)
• Must contain at least one uppercase letter
• Must contain at least one lowercase letter
• Must contain at least one digit

• Inline Error Messages: Validation failures are shown immediately below the password field with a specific explanation. No generic Firebase errors
• Live Clearing: The error clears on every keystroke in the password field, and also when the email field is changed (prevents a stuck form if a "password too similar to email" error was triggered and the user updates their email instead)
• Gated Submit: The sign-up button stays disabled while a password validation error is active

Auto Top-Up Credits via Stripe

Never run out of credits. Configure a balance threshold and Spheron automatically charges your saved card to keep your deployments running.

• Save a Card: Add a payment card via Stripe's hosted setup flow (no card numbers stored; only a Stripe PaymentMethod ID)
• Card Details: Saved card brand, last 4 digits, and expiry are shown in the billing page at all times
• Remove Card: Detach your saved card from Stripe entirely. This automatically disables auto top-up if it was enabled
• Role-Gated Access: Only team owners and admins can save or remove cards; members see card info in read-only mode

• Enable / Disable Toggle: Turn auto top-up on or off from the billing page
• Threshold Setting: Set the balance level (min $5, max $500) that triggers an automatic charge
• Top-Up Amount: Choose how much to charge each time (min $15, max $5,000)
• Immediate Check: Enabling auto top-up immediately checks your balance and triggers a charge if already below threshold
• Failure Banner: A warning banner appears on the billing page if auto top-up was disabled due to a declined charge

• Balance-Triggered Charge: After each credit deduction cycle, if your team balance falls below the configured threshold, a Stripe off-session PaymentIntent is created and charged automatically
• 5-Minute Cooldown: A distributed lock prevents double-charging. Top-ups cannot fire more than once every 5 minutes per team
• Race Condition Safe: Balance is re-fetched inside the lock before charging to prevent concurrent monitor cycles from triggering duplicate charges
• Instant Credit: Team balance is credited immediately on successful charge without waiting for a webhook

• payment_intent.succeeded: Idempotent safety net. Credits the team if the service layer missed it (e.g. network failure mid-request)
• payment_intent.payment_failed: Automatically disables auto top-up and records lastFailedAt when a card is declined

• Auto top-up charges appear in Deposit History labeled "Auto Top-Up" with a distinct badge, clearly separated from manual credit purchases

• Success Email: Confirms the charge amount and shows the new account balance
• Failure Email: Notifies the configuring user that their card was declined and auto top-up has been disabled, with a direct link to re-enable

Mandatory Phone Number on Reserved GPU Form

Required contact info. Phone number is now enforced end-to-end so reserved GPU requests always include reachable contact details.

• Mandatory Phone Field: Phone number is now a required field on the Reserved GPU request form. The label, frontend validation, and server-side validation all enforce it
• Format Validation: Phone input is validated against a format check (supports +, digits, spaces, dashes, parentheses, e.g. +1 555-123-4567 or (555) 123-4567) with a minimum of 7 digits, on both client and server
• Review Step Gate: If contact info (including phone) is incomplete when the user reaches the review step, the wizard redirects back to the contact form with a clear "Contact Info Required" toast notification
• Backwards Compatibility: Existing reservations without a phone number are unaffected. The schema change is non-breaking for legacy documents

Zero-Downtime Deployment & Faster Container Restarts

Instant restarts, no build delays. App builds are now baked into the Docker image so containers spin up in seconds instead of minutes.

• Zero-Downtime Deploy: New script/deploy.sh for all the apps. Builds the new image while the current container keeps serving traffic, then hot-swaps to the new container with no manual downtime
• Health-Gated Rollout: The deploy script waits for Docker's health check to pass (up to 120s) before declaring success, ensuring the new container is fully ready before traffic is handed off

• Build at Image Time: npm run build now runs during docker build (image layer) instead of at container startup. Containers start in seconds rather than waiting for a full compile
• Health Checks Added: All app's Dockerfiles now include HEALTHCHECK directives with 10s intervals and 30s start periods so Docker and the deploy script can reliably detect readiness

Volume Management UI for Voltage Park

Full persistent storage experience. Create, browse, attach, detach, resize, and monitor volumes directly from the dashboard.

• Volumes Page (/volumes): Dedicated page to view and manage all your persistent storage volumes in one place, with status badges, provider/region info, hourly rates, and quick actions
• Create Volume Page (/create-volume): Step-by-step wizard to create a new volume. Select a provider, configure name, size, region, and lifecycle settings before reviewing the cost summary

• Volume Cards: Each volume displays its name, size, provider, region, status (available, attached, creating, deleting, error), and current cost, with one-click copy for Volume ID
• Volume Details Sidebar: Click any volume to open a detailed side panel showing overview, configuration, storage usage metrics, and attached instances
• Attach to Deployment: During the deployment wizard, an "Attach Volumes" step surfaces compatible volumes (same provider and region) and lets you select one to attach before launch
  • Voltage Park instances support 1 volume per instance. The UI enforces this limit automatically
• Detach Volume: Detach a volume from a running instance directly from the instance detail sidebar or the volumes page, without losing data
• Resize Volume: Expand a volume's storage size on-demand from the volumes page (shrinking is not supported)

• Volumes and Create Volume entries added to the sidebar for quick access

• Volume selection resets automatically when you switch providers or networking type in the deployment wizard
• Volume size input clamps to the provider's supported min/max range and rounds to a whole number
• Region matching is normalized so minor formatting differences (e.g. us-east-1 vs US East 1) don't prevent valid volumes from appearing
• Provider pricing is validated before allowing volume creation. A clear error is shown if pricing is unavailable for the selected provider/region

• Hourly and monthly cost estimates shown in real-time while configuring volume size
