DeepSeek V4 Pro 0813

Reasoning tokens are billed as output on deepseek-v4-pro-0813, at $3.96 per 1,000,000 token. They are generated before the visible answer and count toward both latency and spend, so a higher reasoning setting costs more even when the final answer is short.

Before switching production traffic to deepseek-v4-pro-0813, run a pilot on a representative slice of your traffic and check output quality, latency at peak concurrency, and cost per request. Verify the error and retry behaviour, and confirm the request limits you depend on match your plan.

Yes. deepseek-v4-pro-0813 is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to deepseek-v4-pro-0813. Keep your current request and response handling.

deepseek-v4-pro-0813 sits alongside deepseek-v4-pro, claude-opus-4-6, gpt-5.4 in the catalog. Compare them on the dimensions that change your bill and your users’ experience: task quality on your own prompts, latency at your concurrency, context and output limits, and cost per completed task rather than per token.

deepseek-v4-pro-0813 is a reasoning model. Reasoning effort can be tuned per request. Lower effort settings cut reasoning tokens and cost for routine work; reserve higher settings for problems that need deeper search. Measure quality at two or three settings before fixing one in production.
