Ornith releases Ornith-1.5, a 9B model with a mobile build for iPhone and Android

Ornith has released Ornith-1.5, a model family with a 9B dense model, a 35B mixture-of-experts model that activates about 3B parameters per token and a 397B mixture-of-experts model. The 9B model also comes as Ornith-1.5-9B-Mobile, which the company says can be deployed on iPhone and Android devices. Ornith gives no size, memory or speed figures for the mobile build.

The 9B model scores 47.0 on Terminal-Bench 2.1 with the Claude Code harness and 70.6 on SWE-bench Verified in Ornith’s tests. The company says the model matches or exceeds much larger models such as Gemma 4-31B and Qwen 3.6-35B. In the company’s chart, Qwen3.6-35B-A3B leads on SWE-bench Verified with 73.4 and on Terminal-Bench 2.1 with 52.5, while the 9B model scores 86.4 on GPQA Diamond and 54.2 on MCP-Atlas. The previous Ornith-1.0-9B reaches 43.1 on Terminal-Bench 2.1 in the same chart.

According to Ornith, its training loop lets the model propose new tasks, generate task-specific scaffolds and produce solution rollouts, with the reward from the rollouts propagated across all three stages. The company reports that the 35B model scores 67.8 on Terminal-Bench 2.1 with the Terminus-2 harness, against 52.5 for Qwen 3.6-35B. The models are on Hugging Face, with GGUF builds of all three sizes and MLX builds of the 9B and 35B models.
