EDITOR BRIEF
The leaderboard ranks AI models and coding harnesses on best validated NanoGPT speedrun results, with Fable 5 in first place at 2,726. Opus 5 and Kimi K3 follow, while several newer models such as Qwen3.8 Max, DeepSeek V4 Pro, and Grok 4.6 are still marked as running.
COMMENTARY
The results highlight how coding-agent benchmarks are shifting from static accuracy tests toward competitive optimization tasks with time, token, and trace metrics. If these leaderboards gain traction, vendors may increasingly tune models for long-horizon engineering workflows rather than isolated code-generation prompts.
