Training is live. Last week we enabled Deepseek on Fireworks with serverless endpoints, dedicated deployments, and training support. The model provides a 1M-token context window with native tool calling and preserved reasoning history, targeting long-horizon agentic workloads. We ran DeepSeek V4 Pro 0813 through the same eval suite we used for Kimi K3 in July . We evaluated Deepseek against Kimi K3 and Fable 5 across four benchmark families: SWE-Bench Verified, LiveCodeBench v6, Aider Polyglot v1, and Terminal-Bench 2.1. Deepseek V4 Pro is the strongest single model in this combined eval on two of four families.
