🚨More Data on Gemini 4 Pro🚨 1. Releasing possibly in Mid to late October still can slip though 2. they might be introducing more effort levels (Xhigh & Max) 3. A 1M Context window with 256K Max output tokens. We Also got a checkpoint timeline: Sep 4: Argon-160 Sep 9: Argon-a Sep 16: Argon-d Sep 24: barium-b So far its looking great for Google especially with the leaked benchmarks; its a beast.
