Laguna M.1 and XS.2 are new Mixture‑of‑Experts foundation models optimized for long‑horizon, agentic coding. M.1 packs 225.8 B parameters (23.4 B active) while XS.2 has 33.4 B total (3 B active) and its weights are released under Apache 2.0. Both achieve state‑of‑the‑art results on SWE‑bench and Terminal‑Bench evaluations.
A little‑known Chinese model, Hy3 preview, has leap‑frogged Claude and DeepSeek on OpenRouter’s token‑usage rankings, driven by a low $0.066/1M‑token price. However, informal tests show its quality lags behind top‑tier models, suggesting its popularity stems from cost rather than capability.
ElevenLabs released Music v2, an AI music‑generation model that can switch genres, languages, and embed sound effects mid‑track while preserving vocal and compositional coherence. It adds granular in‑painting, section‑by‑section composition, and multilingual support, and powers the company’s ElevenMusic, ElevenAPI, and ElevenCreative platforms.
Biohub released a world model of protein biology with ESMC, a language model trained on 2.8 B sequences, ESMFold2 for fast 3‑D structure prediction, and ESM Atlas spanning 6.8 B sequences and 1.1 B predicted structures. All three are freely available on Biohub Platform, enabling researchers to design high‑affinity protein binders for disease targets in days rather than months.
