Anthropic Deprecating Manual Thinking Mode in Claude Opus
Action Required
Applications using the budget_tokens parameter in Claude Opus 4.6 will no longer function correctly, requiring code updates to migrate to the effort parameter.
AI Impact Summary
OpenAI is deprecating the manual thinking mode (budget_tokens) in Claude Opus, transitioning to the effort parameter for controlling model depth. This change impacts users who relied on the budget_tokens approach for fine-tuning thinking depth, requiring them to update their code to utilize the new effort parameter. The move to Claude Opus 4.6 introduces a new, more capable model for complex agentic tasks and long-horizon work, signaling a shift in Anthropic's strategy.
