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.
Evaluated with mini-swe-agent at k=5 on the full task sets: 66 tasks for Terminal-Bench 4.0, 113 for DeepSWE v1.1.
