DeepSeek: DeepSeek V4 Pro 0423
The DeepSeek V4 Pro 0423 is a language model developed by deepseek that handles text input modalities up to 1 MB in context length. It supports tools and reasoning capabilities but does not output structured results. This model may be worth considering for those with specific requirements who value its performance on tasks covered by the blended benchmark score of 78.0 across two independent benchmarks. However, at $3.2 per million output tokens, it is one of the more expensive options available; those prioritizing cost-effectiveness should carefully weigh this price against their needs.
