Merged
Conversation
- Add claude-opus-5 model to claude_code provider in provider.json (1M context) - Classify opus-5 as AdaptiveOnly in ModelSpecificReasoning (adaptive thinking only; drops budget_tokens and sampling params like Opus 4.7/4.8) - Skip redundant interleaved-thinking beta header for Opus 5 - Map claude-opus-5 to 1M context length in Anthropic response DTO Co-Authored-By: ForgeCode <noreply@forgecode.dev>
