When it comes to coding, open source models have evolved from catching up to taking the lead.
Not an exaggeration. Not clickbait. Early this morning, a model family named Ornith-1.0 was released as open source, sweeping all available benchmarks in the most hardcore arena—Agentic Coding.
SWE-Bench Verified: 82.4. Terminal-Bench 2.1: 77.5. SWE-Bench Pro: 62.2. NL2Repo: 48.2. ClawEval: 77.1. Not "close to closed-source levels." It's "closed-source models haven't even publicly reached this score yet."
When it comes to coding, open source models have gone from chasing to leading. And this time, it's a lead across the full parameter range, fully open-sourced under MIT, fully deployable locally. They even provide a GGUF version.
Four Models, One Ambition #
Ornith-1.0 is not a single model; it's a family. Four specifications covering everything from a laptop to a server cluster.
9B Dense. 31B Dense. 35B MoE. 397B MoE.
The smallest 9B can run on consumer-grade GPUs. The largest 397B MoE is aimed at enterprise-level private deployment. It is post-trained on top of Gemma 4 and Qwen 3.5—standing on the shoulders of giants and…
