CalibForge-35B-A3B

Overview of CalibForge and its evaluation results

📄 Paper · 💻 Repository · 🤗 Dataset · 🤖 30B Model

CalibForge-35B-A3B is a terminal-agent model fine-tuned from Qwen3.5-35B-A3B using full-parameter, multi-turn supervised fine-tuning. Its training trajectories were distilled from 5,431 calibrated terminal tasks spanning 16 domains. CalibForge uses verified solver outcomes and full trajectories to revise executable terminal tasks toward a solver-relative learnable zone. See the paper for the task-construction pipeline.

Evaluation Results

Model	Terminal-Bench 2.0 Acc. (%) ↑	SWE-bench Pro Resolved (%) ↑	Doc2Repo Pass Rate (%) ↑
Qwen3.5-35B-A3B (base)	39.10 ± 1.09	41.29	44.92 ± 1.14
CalibForge-35B-A3B (this model)	47.57 ± 0.99	44.32	48.77 ± 0.90

Terminal-Bench 2.0 and Doc2Repo results are reported as mean ± SEM over three runs; SWE-bench Pro is evaluated once. Terminal-Bench 2.0 uses CalibForge-Eval with a 500-step limit, a one-hour per-task timeout, and sandboxes capped at 16 CPUs and 32 GB RAM. SWE-bench Pro and Doc2Repo use their official evaluation scaffolds; corresponding AweAgent recipes are available for SWE-bench Pro and Doc2Repo through BeyondSWE. See the paper for comparisons with other training-data sources and for the complete evaluation and decontamination protocols.
