Gemini 4 Pro / Flash: benchmarks, hands-on tests and leaks

User 0xtoberry says the Gemini 4 model codenamed Argon will not go live today, dampening hopes for those waiting on the release.

A post says Argon is priced at $4/$20 globally and $2/$10 for Flex/Batch, focuses on coding and cybersecurity, and will first open to paid API customers and AI Ultra subscribers.

NFT_Chen posts a prayer, with a video, that Gemini 4 Argon won't follow in the footsteps of its predecessor models if it launches tonight.

Argon-related strings and Ultra upgrade flows have appeared in Gemini/Antigravity builds, and Google confirmed Ultra users are next in line.

A Japanese poster expects GPT-6.1 Astra to be delayed for about a month, sees Gemini 4 Argon as more likely to open first, and says Fable 5.5 is now waiting on Argon.

A leak says Argon is close to release and will go first to Ultra subscribers and paid API customers at a minimum of $99.99 a month, with Google's own table showing it ahead on 12 of 18 benchmarks while Artificial Analysis scores it 53, tied with GPT-6 Astra and behind Opus 5.5 at 58.

The post complains that Google announced Gemini 4 Argon but regular users can't find it anywhere, questioning whether it is just for show.

A post claims Gemini 4 Argon may launch today or tomorrow, is already in Google Cloud and visible to about half of users, with global pricing of $4 input and $20 output per million tokens.

A leak says Argon was first given to Fairwind cyber-defense testers, has appeared across Google's developer ecosystem, and some early results claim it beats GPT-6 Astra on several tasks.

The author compiled a list of screenshots showing Gemini 4 revealing its identity across various interfaces and answers, as pre-launch leak evidence.

The model ID gemini-4-argon-cyber-permissive showed up on GCP Vertex at $2/$10 per million tokens, a version without cyber guardrails intended first for Fairwind defenders.

A leak says Gemini 4 Argon was first opened to Fairwind cyber-defense testers and goes fully live today, with early tests showing it outperforming GPT-6 Astra.
