What it means for business
  • More open-weight models to choose from, under a mix of licences.
  • Artificial Analysis scores from before 27 Oct do not compare with today's.
  • Firms with US federal contracts should review the DeepSeek order.

The month in brief

Meta, Reflection AI, NVIDIA and Recursive (all US) released Open-weight model: A model whose weights the lab publishes, so you can download it and run it on your own hardware. Glossary models in October, alongside new releases from DeepSeek and MiniMax (both China). The highest-scoring downloadable models remain DeepSeek V4.1-Flash-1017 and GLM-5.3 (both China, 32 on AA v5), with Muse Spark Open (Meta, US) at 25. Artificial Analysis moved to Intelligence Index v5 on 27 October and every score dropped, so older numbers no longer compare. And DeepSeek V4.1-Flash-1017 now runs in mainline llama.cpp.
