Ornith-1.5 Released: 9B Model Competes with Larger Peers, MIT Licensed for Commercial Use
Shruti_0810 · x · 2026-08-20
Ornith-1.5 is a family of open-source LLMs (including 9B Dense, 35B MoE, and 397B MoE) trained with end-to-end self-improvement strategies.
Key Features:
- Performance: The 9B model competes with much larger models on various benchmarks; overall performance is comparable to Claude Opus 4.8 in reasoning, agentic, and coding tasks.
- Terminal-Bench 2.1: 86.1
- SWE-Bench (Verified): 86
- Tool Decathlon: 71.2
- Training Mechanism: Implements a complete self-improvement loop—generate tasks → build scaffolds → solve → learn → repeat.
- Open Licensing: All content, including FP8, GGUF, MLX, and NVFP4 quantized versions, is released under the MIT License, with no restrictions on commercial use.
