test(fireworks_ai): stop pinning vision support on minimax-m3

[devin-ai-integration]

TLDR

Problem this solves:

• Fireworks tests hardcode supports_vision: true for minimax-m3
• The Fireworks models API reports minimax-m3 as text only
• Price sync PR chore(prices): sync Together AI prices: 6 models, 6 deprecated [sync failed: Google Gemini] #41570 follows the API and fails those tests

How it solves it:

• Stop asserting a vision value for the minimax-m3 catalog entry
• Move the vision helper tests onto llama-v3p2-11b-vision-instruct

Pre-Submission checklist

• I have added meaningful tests
• The handful of test files covering my change pass locally, e.g. uv run pytest tests/test_litellm/<your_test_file>.py -v. Leave the suites (make test-unit-*, make test-unit) to CI: it finishes in ~15 minutes where a laptop takes an hour or more
• My PR passes all required CI/CD checks (e.g., lint, schema.d.ts sync check, etc.)
• My PR's scope is as isolated as possible; it only solves 1 specific problem
• I have received a Greptile Confidence Score of at least 4/5 before requesting a maintainer review (Greptile reviews automatically once the PR is opened; only comment @greptileai to re-request a review after pushing changes)

Screenshots / Proof of Fix

Raw provider evidence, fetched today with a cache buster from GET https://api.fireworks.ai/v1/serverless/models:

accounts/fireworks/models/minimax-m3
  input_modalities:  ["text"]
  output_modalities: ["text"]

The sync writes supports_vision from input_modalities, so the catalog value is what the provider publishes. The tests pinned the opposite

The changed tests pass against both the main catalog and the #41570 catalog:

python3 -m pytest tests/test_litellm/llms/fireworks_ai/chat/test_fireworks_ai_chat_transformation.py tests/test_litellm/test_utils.py -q -k "fireworks or vision or transform_messages"
120 passed, 378 deselected

Type

✅ Test

Caveats (if any)

Low

• The minimax-m3 entry no longer pins vision either way; the other Fireworks rows still do

Note

Low Risk
Test-only updates to Fireworks model metadata and vision helper coverage; no runtime or production behavior changes.

Overview
Test-only change so Fireworks catalog tests match provider-published supports_vision instead of hardcoding vision on minimax-m3.

The shared Fireworks model-cost parametrization now uses None for minimax-m3’s expected vision flag and only asserts supports_vision when that expectation is set. Vision behavior tests in the Fireworks chat transformation suite were retargeted from minimax-m3 to llama-v3p2-11b-vision-instruct (including _transform_messages_helper image cases).

This unblocks the price/catalog sync in PR #41570, where the Fireworks API reports minimax-m3 as text-only.

Confidence Score: 5/5

The PR appears safe to merge because it only removes an unstable provider-owned expectation while retaining relevant capability and transformation coverage

Summary

This test-only PR stops requiring minimax-m3 to support vision and moves Fireworks image transformation coverage to a cataloged vision model

• Allows the minimax-m3 catalog capability to follow synchronized provider metadata
• Uses llama-v3p2-11b-vision-instruct for positive vision and image pass-through checks
• Preserves shorthand Fireworks capability coverage elsewhere
