DeepSeek-V3.1

DeepSeek-V3.1 is a large language model API designed for building advanced, production-grade AI applications. It supports natural language understanding and generation tasks such as drafting content, summarization, translation, rewriting, and multi-step reasoning. The model is optimized for tool use and function calling, allowing developers to integrate external APIs, databases, and internal tools so the model can retrieve data, execute actions, and return structured outputs.

DeepSeek-V3.1 offers controllable output formats, including JSON-mode responses, which are useful for workflows that require reliable parsing and automation. It can handle long-context inputs, enabling analysis of extensive documents, logs, or conversations in a single request. The model is suitable for building chatbots, coding assistants, knowledge-base Q&A systems, and workflow automation agents that need to follow instructions consistently and maintain context over multiple turns.
