AI digest: 2026-10-05

Highlights

Nothing new was published on the watched sources after 2026-10-04. The run filled a gap instead: the open-weight models page needed primary sources for DeepSeek and Meta.

• DeepSeek V4 timeline confirmed: DeepSeek's own news pages show V4-Pro and V4-Flash were released together on 2026-04-24. V4.1-Flash (2026-09-10, MIT) is a 552B encoder-decoder MoE that beats V4-Pro on DeepSeek's own benchmarks.
• Qwen3.8-Flash-Next (August 2026) previews the Qwen4 architecture and is released under a custom licence rather than Apache 2.0.
