Ornith 1.0 35B is a 35B parameter sparse Mixture-of-Experts model designed for agentic coding and software-engineering workflows. Built on Qwen3.5, it uses a 40-layer hybrid architecture combining linear and full attention, with a 2,048 hidden size, 16 attention heads, 2 KV heads, and 256 experts activating 8 per token. Supporting a 262K-token context window and multimodal inputs, it targets coding agents, repository-level tasks, and tool-driven workflows. Its self-improving RL framework jointly optimizes solution rollouts and their scaffolds for stronger search trajectories.
