Ampersand, our collaborator model, is now on Vercel AI Gateway - use it free for the next week! Ampersand matches or beats all frontier models (e.g. Fable and Astra) in multi-user long-horizon settings on our evals, and most on external cooperation and multi-agent coding evals, at 744b params (40b active)
Co-Coding: frontier coding by working together We trained Ampersand to work better with people - and found that multi-agent Ampersand matches frontier coding models while being faster and cheaper, despite no extra coding training - 92.2% on SWE-bench Pro v2 HARD-51, matching Fable 5.1 (while 70% cheaper) and Gemini 4 Argon and outperforming Astra, Muse Wonder, and Kimi K3 - 77.9% on DeepSWE v1.1, on par with Gemini 4 Argon and ahead of Astra, Grok-4.7, Kimi K3, and Deepseek-v4-pro Try co(llaborative)-coding with Ampersand’s multi-agent mode, available exclusively through our Agent API…
