Tinfield 1
Tinfield 1 is an agentic model for terminal work and long-horizon software engineering.
It scores 33.0 on Terminal-Bench 4.0, ahead of Claude Opus 4.8 at 23.6 and Claude Sonnet 5 at 12.4, and 62 on DeepSWE v1.1, ahead of Qwen3.8 Max, DeepSeek V4 Flash and Opus 4.8 again. On the Terminal-Bench board it is the second open-weight model, on a leaderboard otherwise made up entirely of frontier closed models.
It does that on 6.6B active parameters per token out of 177B total, and the quantized builds run on a single 64 GB machine.
Built on Qwen3.8-Flash-Next. 256k context, BF16 weights.
