Developer criticizes closed-source models for hiding Chain of Thought
johnnyApplePRNG · reddit · 2026-08-22
A developer building an Agent on DeepSeek noted that closed-source APIs hide the full Chain of Thought, making debugging difficult. He argues that tools like Codex and Claude Code obscure the "compaction" process, leaving developers unsure if the model retained key information. In contrast, open models allow full reasoning visibility, offering a significant advantage for Agent development.
