Nvidia is acquiring HuggingFace for $13 billion, nearly double its initial January 2026 offer, as the platform doubles its customer base in 2026. Simultaneously, Z.ai has formally launched GLM-5.3-Flash, a natively multimodal open-weight model previously known as Ox Alpha.

  • GLM-5.3-Flash features 320B total parameters with 18B active, a 1M-token context window, and an MIT license.
  • It runs on Chinese AI chips and is available via weights, API, chat, ZCode, coding plan, and AutoClaw.
  • Artificial Analysis reports an Intelligence Index score of 57, tying GPT-5.6 Terra and Muse Spark 1.2 at a significantly lower cost per task ($0.09).
  • The model claims to outperform GLM-5.2 at every effort level and match Claude Opus 4.8 on coding benchmarks.

The acquisition highlights Nvidia's consolidation of the open-source AI ecosystem, while the new model launch demonstrates competitive pricing and performance from Chinese frontier labs.
