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

A joke post says Google will ship a faster-than-light Gemini 10.5 Flash in 2030, and that Gemini 4 Argon is coming soon.

Google has announced Gemini 4 Argon, but non-Ultra users still can't access it, and the poster speculates it may open officially today.

A leak shows Argon priced at $2 per million input tokens, $0.10 cached and $10 output, with early benchmark comparisons against Opus 5.5 and GPT-6 Astra.

The poster says the Antigravity client now includes Argon's High, Medium and Low model IDs, and guesses a launch today, possibly first for Ultra subscribers.

The poster says the Google team is no longer posting vague teasers, which they take as confirmation that Gemini 4 Argon arrives today.

A Japanese tech night roundup says Gemini 4 Argon launched for Ultra subscribers that day, with TestingCatalog reporting official confirmation, while users hope it won't stay Ultra-only.

The post expresses hope that Google will finally give regular, non-Ultra users access to Gemini 4 Argon today.

A billing listing shows a Contributor tier priced at $2 per million input tokens, $0.10 cached and $10 output, the same as regular Argon, prompting the poster to ask why contributing data isn't cheaper.

A user says Google Antigravity 2.23.0 contains gemini-4-argon-low, -medium and -high in its code, though Argon still isn't publicly selectable, suggesting preparation for a wider rollout.

A Chinese user shares Gemini 4 Argon contributor-tier pricing, estimates the full price matches Opus 5.5, and says Argon averages 62K output tokens per task versus 27K for Astra.

ash_twtz says it took about 20 master prompts on high effort to use up AntiGravity's 5-hour Gemini 3.8 Flash quota, and hopes Gemini 4 Argon keeps the same generous limits.

A user reports that Gemini 3.8 Flash seems to be routed to a new model, possibly Gemini 4 Argon, with noticeably better output, and shares a prompt to test it.
