Technical notes and benchmarks
DeepSeek reports a 671B-parameter model trained on 14.8T tokens, trained for about two months on an Nvidia H800 cluster, with an estimated cost of about $5.5M. On Codeforces, DeepSeek V3 scored higher than Llama 3.1 and GPT-4o.
Benchmark disputes
Independent testing highlights that results vary by evaluation method. For example, Alessandro Quadron reported different scores for OpenAI o1 depending on the framework, and found DeepSeek V3 roughly comparable to o1 in programming tasks, while Anthropic Sonnet 3.5 scored higher in that setup.
