Capabilities
Ornith 1.0 397B
Ornith 1.0 397B is a 397B parameter sparse Mixture-of-Experts model designed for high-performance agentic coding and software-engineering workflows. Built on Qwen3.5, it uses a 60-layer hybrid architecture combining linear and full attention, with a 4,096 hidden size, 32 attention heads, 2 KV heads, and 512 experts activating 10 per token. Approximately 17B parameters are active per token, with a 262K-token context window and multimodal support. Its self-improving RL framework jointly optimizes solution rollouts and scaffolds, enabling stronger search trajectories and higher-quality coding solutions.
