Ornith 1.0 is DeepReinforce's first open-source family of agentic coding models, trained with a novel self-scaffolding reinforcement learning approach: rather than using a fixed hand-engineered execution harness, the model jointly proposes both the scaffold and the solution during RL training, then iteratively refines both. The family announcement names four variants: 9B Dense, 31B Dense, 35B MoE, and 397B MoE. Public Hugging Face repos are verified for 9B, 35B, and 397B; the 31B variant was not publicly accessible as of June 27, 2026. Models are MIT-licensed and support OpenAI-compatible tool calls for agent frameworks. Released June 25, 2026.
