Feyospace-v1.1-small is the updated small checkpoint in the Feyospace family of open-weight cyber agents, developed by the Feyospace Team at Vera Praxis. It is referred to as Feyospace-s1 (v1.1) in our release blog. The model targets vulnerability research, CTF tasks, and long-horizon security workflows that combine reasoning with tool use. It achieves an 84.4% verified success rate on CyberGym under a general agent harness and 65.57% on pooled CTF suites. The checkpoint follows the Qwen3.5 architecture and contains approximately 28B parameters. We release BF16 Safetensors weights together with the tokenizer, processor, and chat template. The context length above comes from the released…
