DeepSeek V4 Pro
Best for: Developers and enterprises needing maximum performance, deep reasoning, and advanced agentic capabilities for complex, high-context tasks.
V4 Pro marginally trails Google Gemini 3.1 Pro (3-6 months lag) but matches Anthropic Claude Opus 4.6, GPT-5.4, and Gemini 3.1 on major benchmarks, according to MIT Technology Review. It outperforms GPT-5.2 and Google Gemini 3.0 Pro on some tasks, matches GPT-5.4 in coding, and surpasses all rival open models for maths and coding, according to TechCrunch. This positions DeepSeek V4 Pro as a top-tier performer, especially considering its open-weight status and cost efficiency.
Strengths: Leading open-weight scale, advanced agentic and reasoning, strong benchmark performance, competitive pricing. | Limitations: Marginally trails absolute frontier models in some areas. | Price: $1.74 per million input tokens (cache miss), $0.145 per million input tokens (cache hit), $3.48 per million output tokens.
DeepSeek V4 Flash
Best for: Cost-sensitive applications, high-throughput scenarios, and developers needing fast response with strong reasoning.
V4 Flash provides similar reasoning to the Pro version, with faster response times and cost-effective usage, according to Al Jazeera. Its performance is comparable to GPT-5.4 in coding, according to TechCrunch. This model democratizes access to advanced reasoning capabilities for a wider range of applications.
Strengths: Exceptional cost-effectiveness, fast response, strong reasoning for its price, large context window. | Limitations: Smaller scale than Pro, less suitable for the most complex agentic tasks. | Price: $0.14 per million input tokens (cache miss), $0.28 per million output tokens.
Google Gemini 3.1 Pro
Best for: Enterprises seeking a frontier model with robust performance across general and specialized tasks.
DeepSeek V4 Pro marginally trails Gemini 3.1 Pro by 3-6 months but matches its performance on major benchmarks, according to TechCrunch.
