feat: runware list models api

[TejasGhatte]

Summary

Runware's ListModels previously returned an "unsupported operation" error. This PR implements it by sweeping Runware's curated model catalog via the modelSearch task type, converting results into the standard BifrostListModelsResponse format with modality information derived from each model's io: capability tags.

Changes

• Replaced the stub ListModels implementation with a paginated catalog sweep scoped to Runware's curated source, stopping on the first short page rather than trusting totalResults (which Runware reports inconsistently).
• Added RunwareModelSearchRequest, RunwareModelSearchResponse, RunwareModelSearchResult, RunwareModel, and RunwareModelCreator types to represent the catalog API.
• Added ToBifrostListModelsResponse to map catalog entries to schemas.Model, using the AIR as the Bifrost model ID, deriving input/output modalities from io:<from>-to-<to> capability tags, and populating name, description, owner, created timestamp, and architecture fields.
• Set runwareModelSearchPageSize to 500 (above the documented 100 maximum that Runware honours) to fetch the entire curated set in a single round trip, avoiding multiple sequential page fetches that would exceed request deadlines.
• Added runwareCuratedSource constant to scope sweeps away from the ~273k community LoRA uploads that dominate the unfiltered catalog.
• Added runwareModelArchitecture to derive schemas.Architecture from io: tags, returning nil when no modality information is present so the field stays absent rather than empty.
• Added tests covering provider-prefixed AIR as model ID, field mapping, modality derivation from io: tags, and allowlist filtering.

Type of change

• Feature
• Refactor
• Documentation
• Chore/CI

Affected areas

• Core (Go)
• Transports (HTTP)
• Providers/Integrations
• Plugins
• UI (React)
• Docs

How to test

go test ./core/providers/runware/...

To validate end-to-end, configure a Runware key and call the ListModels route. The response should include curated models with provider-prefixed AIRs as IDs, populated modality fields derived from io: capability tags, and correct allowlist/blocklist filtering.

Breaking changes

• Yes
• No

Related issues

Security considerations

No new secrets or PII handling introduced. The Runware API key is passed through the existing key management path unchanged.

Checklist

• I read docs/contributing/README.md and followed the guidelines
• I added/updated tests where appropriate
• I updated documentation where needed
• I verified builds succeed (Go and UI)
• I verified the CI pipeline passes locally if applicable

📝 Walkthrough

Summary by CodeRabbit

• New Features
  • Added Runware model discovery through the standard interface.
  • Included model metadata, creators, capabilities, architecture, aliases, and creation timestamps.
  • Added paginated retrieval of the curated model catalog with filtering and allowlist support.
  • Expanded catalog coverage with additional Runware model information.
• Bug Fixes
  • Replaced the unsupported model-listing response with functional discovery.
  • Improved handling of incomplete or failed catalog responses.
  • Improved image input normalization for URLs, base64 data, and asset references.
  • Invalid image references now return clear validation errors instead of being silently dropped.

Walkthrough

Runware now supports paginated curated model listing and converts catalog entries into filtered Bifrost responses. Image references are normalized and validated. Provider harness coverage includes image, editing, controlnet, asynchronous retrieval, and video scenarios.

Changes

Runware model listing

Layer / File(s)	Summary
Model search contracts core/providers/runware/types.go	Adds task, request, response, pagination, model, and creator definitions for catalog searches.
Paginated catalog retrieval core/providers/runware/runware.go, core/providers/runware/models.go, framework/modelcatalog/models.go	Requests curated catalog pages, handles task errors, records latency, converts accumulated results, and supplements live models with datasheet models.
Model conversion and validation core/providers/runware/models.go, core/providers/runware/models_test.go	Applies filters and aliases, maps metadata, derives modalities and architecture, skips entries without AIR identifiers, and tests the conversion behavior.

Runware image handling

Layer / File(s)	Summary
Image reference validation and normalization core/providers/runware/images.go, core/providers/runware/images_test.go	Normalizes URLs, data values, and Runware asset IDs. Invalid references now return errors.
Runware request and output coverage tests/e2e/api/collections/provider-harness.json	Adds image generation, image editing, controlnet, asynchronous retrieval, video prompt, dimension, and typed output-format cases.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 0f968

The PR adds Runware model listing and modifies image-related behavior and tests, but the configured page size exceeds the documented API limit and may cause every model-list request to fail. Open correctness and validation issues could also silently alter image edits or allow invalid provider cases to pass unnoticed, so these bounded risks should be fixed or explicitly accepted before merging.

Add table-driven retrieval coverage.

The tests only call ToBifrostListModelsResponse. They do not cover listModelsByKey pagination or provider-error handling.

Add cases for a short final page, an empty data response with errors, and the request offset sequence. Run the provider suite with make test-core.

As per coding guidelines, apply “table-driven coverage for behavior changes.”

Tighten the bare-base64 assertion.

to.not.include('invalid') matches any provider or gateway message that contains the word "invalid". The check can fail for reasons unrelated to base64 normalization, and it gives no signal on success. Assert the specific error text that an unnormalized base64 input produces, as the neighbouring edit cases do with "Unsupported use of 'seedImage'".

Use two distinct images in the multi-image edit case.

Both image_url[] entries point to the same asset. If the second image is dropped, the request stays valid and the case still passes unless the provider rejects it for another reason. Use a second, different image so the multi-reference path is actually exercised.

Add an assertion for the 3D prompt drop.

ToRunwareVideoGenerationRequest drops PositivePrompt when the task type is taskType3DInference and an input reference is present (core/providers/runware/videos.go, lines 22-141). This request now sends both prompt and input_reference, so it exercises that branch. The visible diff adds no assertion for it. Add a check that the response does not contain the provider rejection for sending both keys, in the same style as the erase case at lines 133370-133375.

framework/modelcatalog/models.go (1)

22-22: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Verify that Runware is a partial-list provider before enabling this union.

This entry makes computeModelsForProvider append all eligible datasheet models to every non-empty Runware live response. Runware’s current documentation distinguishes modelSearch, which searches the full live catalog, from the curated catalog exposed by content.listModels. (runware.ai)

If RunwareProvider.ListModels uses the full modelSearch catalog, this can expose stale or unlisted datasheet models. Remove this entry in that case. Otherwise, add a Runware regression test proving that the live response is intentionally partial and that unioned datasheet models remain callable. The existing Perplexity test in framework/modelcatalog/pool_test.go, Lines 158-199, does not cover this provider.

Conditional fix

 var providersWithPartialListModels = map[schemas.ModelProvider]bool{
