Ornith-1.5-35B-A3B

Ornith AI released Ornith-1.5-35B-A3B, a 36B-parameter mixture-of-experts model with 3B active parameters per token, on August 18, 2026, under an MIT license on HuggingFace. The model achieves 79.0 on SWE-bench Verified and 89.2 on GPQA-Diamond, outperforming dense models like Gemma 4-31B and Qwen 3.6-35B on agentic coding, with a 262K context window and local-friendly GGUF quantizations.

Ornith-1.5-35B-A3B MoE enthusiast ~36B total, ~3B active per token MoE - the local-favorite Ornith-1.5 size, released 2026-08-18. Activates only 3B parameters per token yet outperforms dense models like Gemma 4-31B and Qwen 3.6-35B on agentic coding. 262K context, MIT-licensed on HuggingFace at ornith-ai/Ornith-1.5-35B-A3B GGUF, FP8, and NVFP4 quantizations . - Coding vendor self-reported : Terminal-Bench 2.1 67.8, SWE-bench Verified 79.0, SWE-bench Pro 59.6, NL2Repo 46.2. - Reasoning: HLE 25.6 no tools / 33.4 with tools , GPQA-Diamond 89.2. - Agentic: MCP-Atlas 70.2, Toolathlon-Verified 48.7, ClawEval 72.5. Local-friendly. Runs on enthusiast-class GPUs via GGUF quantizations; a strong open-weight pick for local agentic coding. Vendor benchmarks are claims pending independent replication. - 36.0B - 262k - mit - 🇺🇸 USA - Aug 2026 Scores Run it locally Per-quant memory needs and a static "can you run it?" reference - no rig entry required Can you run it? - reference rigs | Rig | Q4 K M | Q5 K M | Q6 K | Q8 0 | BF16 | |---|---|---|---|---|---| | NVIDIA Jetson Orin NX 16GB | | no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing no - cloud cloud-pricing Fit tiers use the same will-it-run logic as the rig finder.
