3 Key Points

  • What happened

    DeepReinforce, a new AI company, released Ornith-1.0, an open-source model (MIT licensed) available in four variants—9B Dense, 31B Dense, 35B MoE, and 397B MoE. Built on pretrained Gemma 4 and Qwen 3.5, it achieves state-of-the-art performance among open-source models of comparable size on coding benchmarks.

  • Why it matters

    The model's Apache 2.0–compatible licenses (inherited from Gemma 4 and Qwen 3.5) make it freely usable for commercial and derivative work. Early testing shows it handles multi-step agent workflows efficiently, suggesting it may be useful for developers building systems that perform coding tasks autonomously.

  • What to watch

    The 35B MoE variant runs via GGUF format on consumer hardware (20GB version tested); the model generated output at 103 tokens per second in generation tests. DeepReinforce's earliest known publication is a June 2025 paper on CUDA optimization.

FAQ

What base models is Ornith-1.0 built on?
Ornith-1.0 is built on top of pretrained Gemma 4 and Qwen 3.5, both licensed under Apache 2.0.
Can I use Ornith-1.0 commercially?
Yes. Ornith-1.0 is MIT licensed, and its underlying base models (Gemma 4 and Qwen 3.5) are both Apache 2.0 licensed, making the licenses compatible for commercial use.
What hardware do I need to run it?
The 35B MoE variant has been run using the GGUF format in a 20GB quantized version, suggesting it can run on consumer-grade hardware with sufficient memory.
