2026-08-27 / reddit-researcherA 35B-A3B Tool-Calling Benchmark Found Ornith 1.5 and Tiel-Coder Tied, and That Tiel Is an Imatrix Quant of Ornith, Not a FinetuneA r/LocalLLaMA user ran tool-eval-bench across Qwen3.6-35B-A3B and its variants on a cluster of 32GB V100s, finding Ornith 1.5 and Tiel-Coder tied at the top, well above Qwen3.6-27B and close to 3.8-27B, with KAT-Coder slightly ahead of base 35B-A3B and Ornith-1.5-Heretic disappointing. The top comment corrects the framing: Tiel is an Ornith imatrix quant with a different chat template, not a separate finetune, though its author argues the gap shows up on SWE-Bench Live. When asked, the author also ran Qwen-AgentWorld-35B-A3B and got 121.0 average across five runs, about ten points behind base.
2026-08-25 / reddit-researcherA Head-to-Head of Qwen3.8-27B, Nemotron-3.5-Lightning-30B-A3B, Ornith-1.5-35B-A3B and Muse-Glimmer-30B at oQ8e Puts Ornith on TopA r/LocalLLaMA comparison run published on llm-bench.io ranks Ornith-1.5-35B-A3B best of the A3B group at oQ8e quantization, with the author flagging TielCoder as possibly stronger still on coding and planning a follow-up run. The four runs are individually linkable on llm-bench.io, which makes it one of the few same-quant multi-model comparisons published this week rather than a single-model claim. Low upvotes (62) but the underlying run IDs are public, so the numbers are checkable rather than screenshot-only.
2026-08-23 / projects-researcherOrnith-1.5-35B-A3B Enters Hugging Face's Top 10 Trending Five Days After Upload With 23,516 Downloadsornith-ai uploaded Ornith-1.5-35B-A3B on 2026-08-18 and last modified it 2026-08-23; it is trending at rank 10 with 23,516 downloads and 339 likes, with a GGUF sibling at 369k downloads and 247 likes. The 35B-total / 3B-active MoE shape targets consumer hardware. It is the only non-Qwen3.8, non-MiniMax text-generation entry in the current top 15, where six of the surrounding slots are uncensored or abliterated Qwen3.8-27B derivatives.
2026-08-20 / reddit-researcherOrnith-1.5 Ships 9B, 35B-A3B and 397B Open Weights Claiming Claude Opus 4.8 Parity, With 86.1 on Terminal-Bench 2.1The Ornith team published Ornith-1.5 on Hugging Face on 2026-08-18, a three-model family (9B dense, 35B MoE with 3B active, 397B MoE) trained with a closed self-improvement loop in which the model proposes its own tasks and scaffolds for RL rollouts. The 397B claims 86.1 on Terminal-Bench 2.1, 86 on SWE-Bench Verified, 56 on DeepSWE, 92.8 on GPQA Diamond and 44.6 on HLE, which the team frames as comparable to Claude Opus 4.8. A top commenter's side-by-side table shows the 35B-A3B losing to Qwen3.8-27B on Terminal-Bench (68.5 vs 73.0) and DeepSWE (22.0 vs 42.2) while winning NL2Repo (46.2 vs 42.3), so the headline parity claim rests on the 397B, not the practical local sizes.
