Recommended action: Accept 64k, or set completion_kwargs extra_headers anthropic-beta: output-128k-2025-02-19 (Claude 3.7 only per Anthropic docs).
Option: Accept 64k, or set completion_kwargs extra_headers anthropic-beta: output-128k-2025-02-19 (Claude 3.7 only per Anthropic docs). [evidence: official_recommended_action]
Applies when: Using claude-3-7-sonnet / claude-sonnet-4 via SWE-agent
Steps:
1. agent.model.completion_kwargs: {extra_headers: {anthropic-beta: output-128k-2025-02-19}}
2. Or set max_output_tokens explicitly
Expected: The error no longer appears.
