During April 2026, Baslr enhanced the decolua/9router repository by refining how reasoning_effort is handled for Claude Opus 4.6 and Sonnet 4.6 models within GitHub Copilot. They implemented direct Anthropic backend integration by mapping reasoning_effort to thinking.budget_tokens, addressing previous limitations where this parameter was stripped from Claude models. This update restored configurability for specific model versions and enabled a seamless Copilot-to-Anthropic workflow. The work involved backend development and API integration using JavaScript, with a focus on large language model integration. Baslr’s contribution demonstrated a deep understanding of model-specific configuration and backend mapping for advanced AI workflows.
