Regression of #764. Claude Code → Groq (llama-3.3-70b-versatile) returned HTTP 400
because the model was treated as reasoning-capable: supportsReasoning() defaulted to true,
so applyThinkingBudget did not strip reasoning params, and the claude→openai translator
forwarded reasoning_effort (and re-injected it from output_config.effort) — which Groq
rejects on non-reasoning models.
- providerRegistry: mark llama-3.3-70b-versatile + llama-4-scout supportsReasoning:false
(gpt-oss / qwen3-32b keep reasoning — they accept reasoning_effort).
- stripThinkingConfig: also strip output_config.effort so the translator can't re-inject
reasoning_effort downstream.
Regression test: tests/unit/thinking-budget-groq-3258.test.ts (RED before, GREEN after);
existing thinking-budget suites stay green (45/45).
