Open-source Ornith-1.5-122B MoE coding model runs on a desk with 86GB memory

lmoroney · x · 2026-10-22

Ornith released Ornith-1.5-122B, an open MoE model built for coding and agent tasks, developed on top of Qwen3.5 with additional pre/mid/post-training. SGLang shipped day-zero support with reasoning, tool calling, and 262K context; a community recipe runs the 4-bit quant on a DGX Spark in 86GB total memory. The author suggests testing it on real tickets from your own repo before checking leaderboards.
