DeepSeek V3.2 Thinking Tool Calls and Multi-turn State Configuration
V3.2 integrates thinking directly into tool use. Multi-turn tool requests must fully pass back the previous turn's `reasoning_content`; otherwise, the API may return an error or lose the reasoning state. The thinking mode should not be configured with temperature/top_p.

DeepSeek-V3.2's Long-Context and Agent Evidence-Anchoring Workflow
DeepSeek's technical report shows that V3.2 uses large-scale environment and complex-instruction synthesis to train Agent generalization; when using it, organize tool results, task constraints, and verifiable outcomes into a trajectory instead of relying on a single “please think autonomously” instruction.
