Ruby on Rails
Agents on Rails: we added four new models to the benchmark: @SpaceXAI Grok 4.6 (your number 1 request) @ZhipuAI GLM 5.3 (released 3 days ago) @GoogleDeepMind Gemini 3.7 Flash (released 4 days ago) and @AnthropicAI Claude Opus 4.8 …but none of them made it to the top of the leaderboard. As of August 17, 2026: - Most accurate: Still Claude Opus 5. Solved 92% of runs (58 of 63). (With Kimi a close second for a lot less cost.) - Cheapest: GPT-5.6 Luna is still the cheapest from what we can tell. (GLM 5.3 required a subscription, so costs for it are currently unknown.) - Fastest: Luna again, at a median of 3.3 minutes per task. - Best combination of all three: @OpenAI GPT-5.6 Sol. We also updated the insights and shared the full traces of the first two rounds (every command, diff, and verdict) into GitHub for you to explore.
