DeepSeek Tool Calls let a model request an external function, but the model does not execute that function by itself. Your application receives the requested tool name and JSON arguments, validates and authorizes them, runs an approved handler, returns the…
The DeepSeek Vision API is DeepSeek’s hosted image-understanding capability for developers. It is not a separate endpoint or a model named deepseek-vision. To analyze images, use the current deepseek-flash model through DeepSeek’s Chat Completions, Responses, or Anthropic-compatible API. You can…
Last reviewed: November 7, 2026 Yes, you can use DeepSeek in Claude Code. DeepSeek publishes an official integration that points the unmodified Claude Code client to DeepSeek’s Anthropic-compatible endpoint at Claude Code remains Anthropic’s application, but the model requests…
A DeepSeek API key is the secret credential your application uses to authenticate requests to DeepSeek’s developer platform. To get one, sign in to the official DeepSeek API Keys page, create a key using the control currently shown in the…
Last reviewed: November 7, 2026 DeepSeek currently publishes account-level concurrency limits for model inference rather than a standard public table of requests per minute or tokens per minute. The documented limits are 2,500 concurrent requests for deepseek-flash and 500 concurrent…
Last reviewed: November 7, 2026 The quickest way to request DeepSeek JSON Output through Chat Completions is to set response_format to {“type”:”json_object”}, explicitly tell the model to return JSON, describe the required fields, and reserve enough output tokens for the…
Yes, you can use the OpenAI SDK with DeepSeek. Install the official openai client library, authenticate with a DeepSeek API key, point the client to , and select a current DeepSeek model such as deepseek-flash or deepseek-v4-pro. The OpenAI SDK…
Published: November 7, 2026. DeepSeek Context Caching is an automatic, disk-based prefix cache built into the DeepSeek API. It can reduce the cost of repeated input when a later request fully matches a prefix unit that DeepSeek has already persisted.…
Published: November 7, 2026. DeepSeek Thinking Mode makes the model perform a deliberate reasoning pass before it delivers its final answer. It is most useful for multi-step analysis, difficult coding problems, planning under constraints, and tool-based agent workflows. It is…
Published: November 7, 2026. A DeepSeek API error is fastest to fix when you first determine whether the client received an HTTP response. Capture the status code and a sanitized copy of the error body, confirm the request actually went…
