Gemini 4 Carbon arrives just in time to feel like yesterday's news in the fastest model cycle yet

Google has released Gemini 4 Carbon, which it says complements rather than replaces Gemini 4 Argon, targeting complex multi-step coding, debugging and open-ended scientific research. Anthropic's newly unveiled Fable 5.2 outperforms Carbon in the Artificial Analysis test even at lower reasoning intensity, though Carbon costs far less per task. Google also previewed a "/swarm" feature in Antigravity and reported that Carbon achieved a zero percent prompt injection success rate on the Gray Swan IPI benchmark.
