Current status

Paid public access from Oct. 13, 2026. Google says the rollout is global. Pro and Ultra subscribers get the Gemini app and AI Mode; the paid API and Gemini for business are separate, and API docs exclude the free tier and the Google AI Pro plan. Introductory price is $2/$10 per million tokens through Nov. 30, 2026, then $4/$20. The Oct. 13 safety post and model card are published. The model card says biological and cybersecurity critical capability levels cannot be ruled out, with safeguards assessed to lower residual risk below those levels. External bio red teaming unlocked less than 1% of tested bio sub-tasks; Gray Swan indirect prompt-injection attack success was 0.7% across 15 adaptive attempts.

DeepMind announces Gemini 4 Carbon with limited access
Google said on Oct. 28, 2026 that Gemini 4 Carbon is its next frontier model, at introductory prices of $2 per million input tokens and $10 per million output tokens, the same introductory rates as Gemini 4 Argon. Access this week is limited to a subset of cyber defenders in the Fairwind Program while a U.S. government voluntary pre-release review continues, and the later price of $4 and $20 per million tokens has no published end date for the introductory period. Google reports a score of 59 and first place on Artificial Analysis Intelligence Index v5.0, plus 88.2% on SEC-bench Pro, 54.8% on ExploitGym, and 71.0% on CWE-bench.

OpenAI says GPT-5.6 Sol helped find a critical PHP flaw
OpenAI said on Oct. 21 that a Calif researcher used GPT-5.6 Sol to identify a critical PHP flaw, while Wiz independently reported both vulnerabilities and says its Aug. 19 discovery also used Gemini 4 Argon. PHP released 8.5.12, 8.4.27, 8.3.36 and 8.2.35 the same day for CVE-2026-109618 and CVE-2026-109619, which it says allow unauthenticated remote code execution, and said updating is the only complete fix. OpenAI says the bugs are among several it has found and that it has committed $1 billion in subsidized Daybreak access for frontline defenders.

DeepMind says four Gemini agents beat Minecraft on Easy
Google DeepMind researchers reported on 15 October 2026 that four Gemini 4 Argon agents defeated Minecraft's Ender Dragon in 27 hours and 14 minutes on one random Easy-difficulty world, writing 2,783 programs and dying 605 times, with no human intervention during the run. The agents played through Mineflayer code, which the paper says reveals blocks a player cannot see and plans routes, rather than through pixels and a keyboard. The authors call it a single run, estimate about $520 in introductory list-price tokens up to the win, and note two earlier community dragon kills that used different tools or an easier setup.
