Closes #1064

What changes for users

  • Models page: each model row expands into a details panel with the provider listing (id, owner, created), properties (display name, family, description, modes, categories, tags, context window, max output tokens), capabilities, rankings and effective pricing with the source of each price.
  • Metadata sources: the panel labels every field with the layer it came from (config.yaml, provider, catalog, or inferred from the model id) and can switch to show only the provider's own report, only the ai-model-list catalog entry, or only the config override.
  • New admin endpoint: GET /admin/models/metadata?provider=…&model=… returns the effective metadata plus each layer and a per-field source map. It is fetched only when a row is expanded, so the inventory list endpoint and its payload are unchanged. Nothing new is stored: the layers are already held per model and the catalog entry is resolved on demand.
  • Provider listings: adapters now keep the metadata providers report about their models. New mappings for Groq, xAI, Fireworks, Anthropic, Bedrock and vLLM/SGLang/llm-d; Gemini, OpenRouter, Ollama and Cohere keep more of what they already fetched. Capability names are mapped onto the catalog's vocabulary (function_calling, vision, reasoning, …) so the provider and catalog layers merge one feature under one key. Chutes and llama.cpp previously reported tools, video and audio; those now read function_calling, video_input and audio_input.
  • Layout fix: the app shell is sized from the document instead of 100vh, which removed a second, document-level scrollbar on some viewports.

Provider-specific notes

  • xAI prices are quoted in 1/10,000th of a cent per token and are converted to $/MTok; the long-context rate becomes a second pricing tier.
  • Groq speech models quote the prompt rate per character, mapped to the per-character price rather than a token price.
  • Cohere's features and supports_vision mapping follows the documented listing shape; the live endpoint rate-limited during verification.

Docs: docs/advanced/model-metadata.mdx and docs/advanced/admin-endpoints.mdx; OpenAPI regenerated.

    • Expanded model discovery with richer limits, capabilities, pricing, descriptions, supported modes, and pagination.
    • Added cached-input rates to tiered pricing calculations.
  • Documentation
    • Documented metadata inspection, source precedence, and provider discovery behavior.
  • Style
    • Improved dashboard layout sizing and scrolling behavior.

📝 Walkthrough

Walkthrough

This change adds provider metadata discovery, a metadata-layer API, tier-specific cached pricing, and expandable model details in the dashboard. Provider listings now expose normalized metadata and pricing fields.

Changes

Model metadata feature

Layer / File(s) Summary
Metadata provenance and admin API
internal/modeldata/*, internal/providers/registry_metadata_layers.go, internal/admin/*, docs/openapi.json, cmd/gomodel/docs/docs.go
Added GET /admin/models/metadata. The registry returns effective, provider, catalog, and config metadata with field-level sources.
Provider metadata discovery
internal/providers/*
Provider listings now preserve display fields, capabilities, modes, context limits, pagination, and pricing. Shared helpers normalize capabilities, modalities, and rates.
Tiered pricing
internal/core/types.go, internal/usage/cost.go
Pricing tiers now support cached-input rates. Cost calculation uses the selected tier’s cached-input rate.
Dashboard detail state and rendering
web/dashboard/src/pages/models/*, web/dashboard/tests/models-details.test.js
Expanded model rows load metadata layers, support layer views, display source labels, and clear cached layers after inventory refreshes.
Dashboard UI and localization
web/dashboard/src/pages/overview/ProviderStatusCard.svelte, web/dashboard/messages/*, web/dashboard/src/styles/base.css
Provider cards link to filtered model lists. Localized labels support the details panel. Dashboard sizing uses container height.

Merge Risk: 🟡 Moderate · up to 2a386

Gemini model inventories can silently omit or duplicate models under abnormal pagination. Reject incomplete pagination before merging; strengthen the cached-pricing clone test to protect value preservation.

Explanation

The PR changes web/dashboard/src/styles/base.css to apply global html, body { overflow: hidden; } and changes .app sizing from 100vh to 100%. These changes fix document-level scrolling but do not implement model properties or provider/catalog source distinction for issue #1064. The reviewed head still contains this separate app-shell change.

In `@internal/providers/registry_metadata_layers.go`:
- Around line 16-20: Mark the Provider, Catalog, and Config pointer fields in
the metadata layer type with the x-nullable schema extension, then regenerate
the corresponding OpenAPI artifacts in docs.go and openapi.json so explicit null
values are accepted.

In `@internal/providers/xai/models.go`:
- Around line 37-39: Preserve long-context cached-input pricing across the xAI
pricing pipeline: add the decoded field to the model metadata, propagate it when
constructing tiers in modelInfo, include it in tier cloning, and apply it during
pricingForTokenCount tier resolution. Ensure long-context tiers are created when
only cached pricing is present, and add coverage for both tier values and cost
resolution above the threshold.

In `@web/dashboard/src/pages/models/ModelDetails.svelte`:
- Around line 71-74: Update the capability chip markup to include visually
hidden text for its enabled/unsupported status and optional source, and add the
pricing field hint as visually hidden text alongside the existing decorative
asterisk. Define the model-details-sr-only class using the component’s
established visually-hidden styling, targeting the chip and pricing field markup
without changing visible presentation.

In `@web/dashboard/src/pages/models/modelDetails.svelte.js`:
- Line 46: Update the guard in the layer-loading logic to allow retries for
entries whose status is "error"; skip only existing non-error entries or keys
with an active controller. Use the existing `#layers` and `#controllers` state so
reopening a failed row can call the endpoint again.
- Around line 58-60: Guard both `#dropEntry`(key) calls in the
stale/aborted/unauthorized result path and the isAbortError path with the
existing controller-ownership check, ensuring only the current request for the
key can remove its entry while preserving the existing finally cleanup.
