Bypassing Model Thinking Limits: Free Internal CoT via Custom Tools

ivan_bezdomny · x · 2026-08-12

A user discovered a clever workaround to bypass a model's default thinking restrictions: simply disable the built-in thinking mode and provide a custom tool named deepthink. The model will then actively call this tool, outputting its reasoning process using an internal Chain-of-Thought format within the tool's parameters.

This creative prompt engineering and tool-calling trick unexpectedly extracts the hidden internal CoT, drawing attention and amusement from the community.
