# Ornith 1.5 122B

> Ornith 1.5 122B is Ornith's open-weight mixture-of-experts model for coding and agent work, built on the Qwen3.5 MoE architecture and trained with a self-improvement loop over generated tasks, scaffolds and rollouts. It takes text and image input, supports reasoning and tool calling, and has a 262K-token context window.
