Problem

buildImageGenerationProvider() still advertises two image models that the gateway cannot serve:

| id | status |

|---|---|

| openai/dall-e-3 | gateway returns 400 — delisted upstream 2026-05-25 |

| black-forest/flux-1.1-pro | no gateway entry at all |

Both were removed from IMAGE_PRICING and MODEL_ALIASES in v0.12.227, but the provider list in src/index.ts was missed by that sweep.

This is not cosmetic. OpenClaw's image UI sends the picked entry from provider.models directly as the model field, and the /v1/images/generations handler forwards the request body to the gateway verbatim — there is no resolveModelAlias() pass on that path (unlike /cr-imagegen, which does map the dall-e-3 shorthand to openai/gpt-image-2). So picking either entry in the picker is a guaranteed upstream failure.

The inverse gap exists too: the three image models added since that sweep — openai/gpt-image-2, google/nano-banana-2, bytedance/seedream-5-pro — are priced and aliased, but were never advertised, so they are unreachable from the picker.

The blockrun_image_generation partner tool description carried the same stale pair, pointing agents at both dead ids and using openai/dall-e-3 as its model param example.

This is the same drift class as v0.12.164 (buildImageGenerationProvider advertising only 4 of 8 image models) and v0.12.206 (azure/sora-2 missing from VIDEO_PRICING).

Changes

  • src/index.ts — picker list resynced to the 9 ids the gateway serves; buildImageGenerationProvider exported so it can be asserted on.

  • src/proxy.tsIMAGE_MODEL_IDS exported (derived from IMAGE_PRICING) as the pinning source of truth; two stale --model dall-e-3 hints in user-facing copy and a code comment updated to gpt-image-2.

  • src/partners/registry.ts — tool description model list, shortDescription, and the model param example refreshed.

  • src/index.image-provider.test.ts — new regression test pinning the picker against IMAGE_PRICING, plus explicit assertions on the delisted ids and the live successors.

The IMAGE_MODEL_ALIASES entry mapping the dall-e-3 shorthand to openai/gpt-image-2 on the /cr-imagegen path is deliberate backward compatibility and is left untouched.

Note on the implementation

The picker list is kept as an explicit array rather than spread from IMAGE_MODEL_IDS. Importing that symbol into src/index.ts breaks src/index.lifecycle.test.ts, which fully mocks ./proxy.js and would need the new export added to its mock. The test pins the two lists together instead, which keeps the guard without touching an unrelated test's mock surface.

Happy to switch to the derived form and update the lifecycle mock if you prefer that shape.

Verification

The new test fails on the pre-fix list and passes after:

× only advertises models the gateway can still serve
expected [ 'openai/dall-e-3', 'black-forest/flux-1.1-pro' ] to deeply equal []
× does not advertise models delisted upstream
× advertises the live successors

Full suite after the fix: 721 passed | 3 skipped. tsc --noEmit, eslint src/, and prettier --check src/ all clean.

Note: the 400 on openai/dall-e-3 is taken from the v0.12.227 changelog entry and the removal of both ids from IMAGE_PRICING/MODEL_ALIASES in that release; I did not re-probe the live gateway.

Summary by CodeRabbit

  • New Features

    • Added support for Nano Banana 2, GPT Image 2, and Seedream 5 Pro image models.
    • Exposed the image generation provider for programmatic use.
    • Updated image-generation commands and examples to use GPT Image 2.
  • Bug Fixes

    • Removed retired DALL-E 3 and Flux 1.1 Pro models from supported model listings.
    • Improved guidance shown when image uploads fail.
  • Tests

    • Added validation to ensure advertised image models are current, supported, and include the default model.

The image UI sends the picked id from provider.models straight to
/v1/images/generations, which forwards the body verbatim with no alias
resolution. Two ids there have been dead since v0.12.227:

- openai/dall-e-3 — gateway 400s (delisted upstream 2026-05-25)
- black-forest/flux-1.1-pro — no gateway entry at all

Both were dropped from IMAGE_PRICING and MODEL_ALIASES in that release,
but buildImageGenerationProvider was missed, so picking either one is a
guaranteed upstream failure. The three live models added since
(gpt-image-2, nano-banana-2, seedream-5-pro) were never advertised.

Same drift class the blockrun_image_generation tool description carried,
which pointed agents at the same two dead ids.

- picker list resynced to IMAGE_PRICING's 9 gateway-served ids
- IMAGE_MODEL_IDS exported from proxy.ts as the pinning source of truth
- partner tool description and model-param example refreshed
- stale --model dall-e-3 hints in user-facing copy updated

src/index.image-provider.test.ts pins the picker against IMAGE_PRICING so
the two cannot drift apart again; it fails on the pre-fix list.

📝 Walkthrough

Walkthrough

The image generation provider is now exported for programmatic use. Its advertised models, registry metadata, command help, and failure guidance now use current model IDs. Tests validate model-list consistency and successor coverage.

Changes

Image model catalog

Layer / File(s) Summary
Model catalog and provider contract
src/proxy.ts, src/index.ts, src/index.image-provider.test.ts
The provider exports its builder, advertises current image models, and validates model-list consistency against IMAGE_MODEL_IDS.
Metadata and guidance alignment
src/partners/registry.ts, src/proxy.ts
Registry metadata, command help, and upload-failure guidance now reference openai/gpt-image-2 and the updated supported-model set.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to cf31b

The picker now removes unavailable models and adds current successors, but command-based use of nano-banana-2 may still fail because its shorthand is not mapped to the canonical model ID. The PR is mergeable with explicit owner awareness or a follow-up alias fix.

Prevent image-catalog drift.

The provider maintains a duplicate catalog, and the test checks only one-way inclusion. A future gateway model can therefore be omitted from the picker without a test failure.

Add the nano-banana-2 command alias.

The catalog advertises google/nano-banana-2, but IMAGE_MODEL_ALIASES has no nano-banana-2 entry. The fallback sends the shorthand nano-banana-2 unchanged instead of the canonical full ID. The help block also omits this new model.

Add the alias and help entry, or document the full model ID.

Proposed fix
           const IMAGE_MODEL_ALIASES: Record<string, string> = {
+            "nano-banana-2": "google/nano-banana-2",
             "banana": "google/nano-banana",
