OpenThinkerAgent-32B-SFT-3.16K
OpenThoughts-Agent is an open-source effort to curate the best datasets for training agents. Our release includes datasets, models and our research codebase.
OpenThinkerAgent-32B-SFT-3.16K is post-trained from Qwen/Qwen3-32B with full-parameter SFT on the 3,160-example OpenThoughts-Agent-SFT-3.16K dataset (Top-4 task sources, GLM-4.7-AWQ teacher in the terminus-2 harness, ≥5-turn trace filter).

Performance
Evaluated in the terminus-2 harness (pass@1, mean over 3 stochastic re-runs):
| Model | Harness | SWE-Bench-Verified-100 | OpenThoughts-TBLite | Terminal-Bench 2.0 |
|---|---|---|---|---|
| Qwen/Qwen3-32B | Terminus-2 | 26.7 | 13.7 | 7.5 |
| OpenThinkerAgent-32B-SFT-3.16K | Terminus-2 | 30.3 | 24.7 | 16.9 |
Data
The model is trained on OpenThoughts-Agent-SFT-3.16K: (task, agent-trajectory) pairs from the Top-4 task sources (SWE-Smith, StackExchange-SuperUser, StackExchange-Tezos with synthetic augmentation, IssueTasks). Trajectories are generated by GLM-4.7-AWQ in the terminus-2 harness and filtered to traces with at least 5 model turns.
