Independent test finds current AI models unreliable at identifying dangerous mushrooms

The Register reported on September 2, 2026 on an independent test by Piotr Migdal running 1,040 mushroom photos across 16 models. Gemini 3.8 Flash scored best (65% correct on first guess, 85% within its top five), while Qwen3.8-27b scored worst (13% first-guess, and misidentified poisonous mushrooms as edible 36% of the time). Meta's Muse Spark 1.2 had the lowest false-positive rate (8%) largely because it declined to guess in ambiguous cases.

Gemini adds agentic video understanding, cutting long-video token use up to 88%

On September 1, 2026, Google DeepMind and the Gemini API released agentic video understanding for Gemini 3.7 Flash, 3.6 Flash, and 3.5 Flash-Lite, letting the model dynamically request transcripts, frames, or audio tracks from a video timeline on demand rather than processing it statically. Google reports this uses up to 88% fewer tokens for long-form video content compared to static processing.
