The unreleased checkpoints on Arena are disappearing. Kibitz (Kimi K3.1), Kalmia (Qwen 4), and the new gemini-4-argon checkpoint (Gemini 4 Carbon) have all left Arena. If you still get matched to it, expect errors before it even writes a single line of code Kimi already dropped their K3.1 teaser few hours ago Gemini 4 Carbon might be coming sooner than expected?
