Ornith 1.5 open models match Claude Opus 4.8 on coding benchmarks
An open-source model family just posted numbers that rival one of the most capable closed models in the world — and it's available under an MIT license. Ornith 1.5, released today by the Ornith AI team, is a three-model family spanning 9 billion dense parameters up to a 397 billion mixture-of-experts flagship. The big headline: the 397B MoE scores 86.1 on Terminal-Bench 2.1 (Terminus-2) and 86.0 on SWE-bench Verified, placing it on par with Claude Opus 4.8's 85.0 and 85.8 respectively.
