GPT-6 Astra Tops Code Arena at 1797, Fourth Leader Change in a Week
LMArena's Code Arena (WebDev leaderboard) published its latest results: OpenAI's new GPT-6 Astra (Max) took first place with 1797 points, 35 ahead of runner-up Claude Fable 5.1 (Max) at 1762, reshaping the Pareto price frontier. This confirmed earlier community speculation and marked the fourth leader change in a week, underscoring the intensity of coding model competition.
Confirmed
- LMArena officially announced GPT-6 Astra (Max) topping Code Arena: WebDev at 1797 points, 35 ahead of Claude Fable 5.1 (Max) at 1762; the third spot belongs to a Claude model.
- Evaluation method: models plan and build real web apps with tools, judged by pairwise human voting.
- Qwen 3.8 Flash Next entered the top ten.
- Reshares noted this was the fourth leader change within a week.
Timeline (09-06 to 09-07)
- On 09-06, user py-net posted that Astra and Fable 5.1 formed a new top tier clearly ahead of other models, and inferred Astra should rank first by comparing score changes after upgrading from Fable 5 and Sol.
- The same day, LMArena's official account and multiple reshares confirmed GPT-6 Astra (Max) at 1797 points in first place.
- On 09-07, annbordetsky and others reshared, highlighting the four leader changes in one week.
Why it matters
- The leaderboard is based on real web app building with human pairwise comparison, giving it strong reference value for practical coding ability; py-net argued Arena's coding benchmark this time accurately reflected real-world programming skill.
- Astra's 35-point lead and reshaped Pareto frontier suggest OpenAI's new model sets a new benchmark on both performance and price-performance, potentially influencing future model pricing and competition.
- Frequent leader changes within a week show top coding models are iterating rapidly and the competitive landscape remains in flux.
