DeepSeek V4 Pro 0813 is the generally available release of DeepSeek V4 Pro, DeepSeek's large mixture-of-experts model. It works on text over a 1M-token context, reasons with low, high or max effort, and has an unusually low input price for its size, which favours long prompts and large documents.

It accepts text input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. DeepSeek V4 Pro 0813 is commonly used for complex reasoning, coding, long-document analysis and agents with large prompts. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $0.45 per million input tokens and $5 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.

DeepSeek V4 Pro 0813 is a large-scale mixture-of-experts model from DeepSeek. This is the GA release of DeepSeek V4 Pro.
