Efficient tier: Solar Mini 4, looped MoE, Olmo-core 3
From the AI digest for Oct 1, 2026
- Upstage Solar Mini 4 (Chosun Biz et al.): 3B-active-param MoE, on-premise speed push — and the Solar lineup splits Pro/Mini, the Korean vendor formalizing the tier.
- Meta loop-scaling-laws writeup (MSN syndication, flag): a half-size looped MoE matching larger models on reasoning — if it replicates, another cost curve for the band.
- Ai2 Olmo-core 3: open, scalable training infrastructure for large MoEs (HF blog) — the open stack under cheaper training runs.
