DeepSeek V4 Pro 0813 API on ModelFold
DeepSeek V4 Pro 0813 is the GA (generally available) release of DeepSeek V4 Pro, a large-scale mixture-of-experts model from DeepSeek. Try DeepSeek V4 Pro 0813 in the ModelFold Playground, then call it from your own code through an OpenAI-compatible chat completions API.
What Is the DeepSeek V4 Pro 0813 API
DeepSeek V4 Pro 0813 at a glance
DeepSeek V4 Pro 0813 is a chat model from DeepSeek. It accepts text as input and returns text, with a context window of up to 1M tokens.
Use it without hosting anything
On ModelFold you call DeepSeek V4 Pro 0813 with a single API key — no model weights to download and no inference servers to run. The same key also works for the other chat, image, video and audio models on ModelFold.
Core Capabilities of DeepSeek V4 Pro 0813
Up to 1M tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Function calling
DeepSeek V4 Pro 0813 supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Adjustable reasoning effort
Choose a reasoning effort level (low, medium or high) per request to balance depth of thinking against speed and token usage.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
