The biggest gap between AI labs isn't whether their agents get the job done. It's whether users actually enjoy working with them. We tracked the best agent from @AnthropicAI , @OpenAI , @GoogleDeepMind , @Kimi_Moonshot , @SpaceXSI and @deepseek_ai across 4 key Agent Arena signals used between late June and the start of October to see how the industry is shifting. Three things stood out: 1. Users like some agents far more than others. On Praise vs Complaint, OpenAI and Anthropic sit at +35 points over the leaderboard average. Moonshot, xAI and DeepSeek land between +5 and +13. No other signal splits the labs this widely. 2. Agents are getting much better at delivery. On Confirmed Success, the average lab's best model went from -4 to +14 points in three months. Anthropic leads with Claude Opus 5.5 (Max) at +20. 3. Labs are converging on error recovery and steering. Since June, the spread between the six labs has more than halved on Bash Recovery (34 → 16 points) and nearly halved on Steerability (19 → 11). In short, the labs are catching up on avoiding failures. Leaving the user happy is where the top three are pulling away. 🔗 View on Twitter
