Ornith 1.5 35B A3B
Ornith 1.5 35B A3B is a text-generation model from the Ornith-1.5 family, identified as its mid-size mixture-of-experts member. It activates approximately 3B parameters per token. According to the official model card, Ornith-1.5 extends Ornith-1.0 by jointly optimizing task generation, scaffold construction, and solution rollouts within a self-improvement loop. The model card reports that it outperforms similar-sized peer Qwen 3.6-35B across all coding and agentic benchmarks, and outperforms dense models such as Gemma 4-31B and Muse Glimmer-30B by wide margins on agentic coding. The repository is listed under the MIT license and is tagged for text-generation with safetensors.
