AI Models & Releases

Google unveiled Gemini 4 Argon on September 30 — its newest frontier model, with dramatically longer outputs and cybersecurity-first early access.

LMArena’s factuality-adjusted rankings weight truth at 25% — GPT-5.5 jumped 13 spots while Meta’s Muse Spark fell 13. Popularity isn’t enough.

Korea’s ETRI built ReAcTree, which nearly doubled task success rates with hierarchical agent teams — a 7B model beat a 72B baseline at long-horizon planning.

Black Forest Labs’ FLUX 3 trains image, video, audio, and robot actions inside one unified architecture — but for now, you’ll need an invite to touch it.

Google’s Gemma 4 family spans 2.3B to 31B parameters, with an encoder-free 12B that reads raw audio — all Apache 2.0 licensed and phone-friendly.

Fish Audio raised $52M on $21M ARR and 8M users — but its open voice models raise cloning-misuse questions that no amount of funding can fix.
