Kling AI drops version 4.0 with stereo audio, multilingual lip sync, and a lighter Flash variant

Kling AI's 4.0 video generator handles clips up to 30 seconds, accepts up to ten keyframe images and understands prompts of up to 8,000 tokens. In comparisons with Wan 3.0 and Seedance 2.5 it keeps pace without clearly winning, which may suggest progress in AI video is slowing.

Mistral Large 4 trails Muse Spark Open by one point, but leads it on agent tests

On Artificial Analysis's index, Meta's Muse Spark Open scores 39 against 38 for the Mistral Large 4 preview, which still wins five of ten tests, including Terminal-Bench and AutomationBench. Large 4 generates far more tokens to run the index and costs more at launch pricing; Muse's licence restricts large-scale resale, while Large 4's licence is unpublished and its weights are promised by October 31.
