DeepSeek V4 Pro 0813

DeepSeek V4 Pro 0813 is a mixture-of-experts language model and the general availability release of DeepSeek V4 Pro, supporting a 1-million-token context window.

Strengths

Handles very long contexts and demonstrates frontier-class capability across general language tasks, reasoning, and code generation.

Best for

Applications requiring extended context windows, complex reasoning, or cost-conscious inference at the frontier tier.

Limitations

Slower than the V4 Flash variant for latency-sensitive workloads; earlier V3 models may be more appropriate if you need only shorter context windows or have already optimized around them.
