Contrastive-LM/CLM-v0.1-8B — new model trending #30 on Hugging Face
Contrastive-LM released CLM-v0.1-8B, a Qwen3-8B contrastive model for fast state-action scoring and agent verification.
Contrastive-LM released CLM-v0.1-8B, an Apache 2.0 System One model that scores candidate actions rather than generating text. Two projection heads on a frozen Qwen3-8B encoder were trained with bidirectional InfoNCE on about 60 million Nemotron Q&A pairs, 30 million synthetic hard negatives, and 1 million agentic trajectories. Zero-shot it matches Jev on computer-use, gaming, and tool use at up to 9× lower latency, and with about 1,000 candidates is 13× faster. Fine-tuned heads reach 81.6% on DeepSWE and 87.6% on Terminal-Bench 2.1; a multimodal CLM-35B is planned for early October.
