DeepSeek-V4-Pro: 1M Context, #1 on LiveCodeBench, Open-Source Frontier You're evaluating open-source models for a production coding agent. You need something that handles large codebases—entire repos, not just single files—and actually resolves GitHub issues without hallucinating tool calls. Every model you try either falls apart beyond 128K tokens or lags behind GPT-4o on the benchmarks that matter for real engineering tasks. TL;DR : DeepSeek-V4-Pro is a 1.6T-parameter open-source MoE model delivering #1 LiveCodeBench score (93.5) and 1M-token context. Available now via Novita AI. DeepSeek-V4-Pro changes this calculus. It's a 1.6-trillion-parameter MoE model with a true 1M-token context window, the highest published score on LiveCodeBench (93.5 Pass@1), and Codeforces Rating 3206—both #1 among all evaluated models including closed frontier APIs. In short: it's the best open-source model available today for competitive coding and large-context agentic tasks, released under MIT license.…
