DeepSeek: DeepSeek V4 Pro

DeepSeek V4 Pro is a text-in, text-out model from DeepSeek with a context window of just over one million tokens and a maximum output of 384,000 tokens, making it suited to long-document work where other models hit limits early. It supports tool use and reasoning, which opens it to multi-step and agentic workflows, though structured output support is unconfirmed in available specifications. At $0.435 per million input tokens and $0.87 per million output tokens, it sits at a competitive price for its capability tier. Its blended benchmark score of 82.5 covers only four benchmarks, so treat that figure as directional rather than comprehensive. Notably, its coding benchmark score reaches 97.9, making it a strong candidate for developer-focused use cases, while its agentic score of 60.0 suggests more caution for fully autonomous pipelines. Teams prioritizing coding throughput at moderate cost have clear reason to shortlist it; teams needing broad verified performance data may want to wait for wider coverage.
