Ornith 1.5 35B A3B

Ornith 1.5 35B A3B is a text-generation model from the Ornith-1.5 family, identified as its mid-size mixture-of-experts member. It activates approximately 3B parameters per token. According to the official model card, Ornith-1.5 extends Ornith-1.0 by jointly optimizing task generation, scaffold construction, and solution rollouts within a self-improvement loop. The model card reports that it outperforms similar-sized peer Qwen 3.6-35B across all coding and agentic benchmarks, and outperforms dense models such as Gemma 4-31B and Muse Glimmer-30B by wide margins on agentic coding. The repository is listed under the MIT license and is tagged for text-generation with safetensors.

Freshness 80 out of 100. Repository age: 58 days old, Aug 18, 2026. Measures age, not quality.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))

Tradeoffs

  • Only text-generation pipeline is specified.
  • No compatibility, performance, or hardware requirements beyond the supplied facts are stated.
  • The supplied source lists MIT license; no additional licensing details are provided beyond the model card.
  • Benchmark claims come from the official model card, not from independent testing.
  • No purchase recommendation or testing claim is made.
