Deepseek V3.2 is DeepSeek's December 1, 2025 model on AI Gateway. It combines tool use with both reasoning and non-reasoning inference modes for agent-style operations.

The key capability: the model supports combined thinking and tool use, handling tool calls in both reasoning and non-reasoning modes. This distinguishes it from models where tool use and thinking mode are mutually exclusive, which previously forced developers to choose between the two.
The context window of 163.8K tokens carries over from earlier V3 generation models. Max output is 163K tokens in standard chat mode. Deepseek V3.2 is the general-purpose variant in the V3.2 release, suitable for use cases from chat interfaces to multi-step agent pipelines. For workloads that need maximum reasoning depth and can tolerate higher token consumption, the DeepSeek V3.2 Thinking variant extends reasoning output up to 64,000 tokens but drops tool-use support.
Access through AI Gateway removes the need for a separate provider account. Authentication uses AI Gateway API keys or OIDC tokens, and the AI SDK provides a direct integration path. You can adopt Deepseek V3.2 without managing DeepSeek platform credentials separately.
