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

A user citing a source says Argon arrives Thursday and notes Google has not released a Pro-tier model since February 19.

A poll on which unreleased model people would use right now put OpenAI's Bel at about 1,711 votes, far ahead of Anthropic's model and Grok 5, with Gemini 4 Pro at only about 165.

A poster argues Gemini 4 Argon has no competitive edge against GPT-6 Sol, GPT-6 Astra, Opus 5.5 and Haiku 5.5, and jokes about organizing its funeral.

After days of rumors, screenshots and speculation, Google has said nothing about Gemini 4 Argon, and users joke that the release date is the biggest feature.

LuminaBench posted more comparison data and confirmed that Argon in its rankings is Gemini 4 Pro, linking to its earlier comparison post.

A commentator says Google's Argon post shows modern C++ is not safe enough, since Google is moving millions of lines to Rust, and that Google still relies on human code review.

A model roundup gives GPT-6 Sol, Opus 5.5 and Haiku 5.5 each an award, while naming Gemini 4 Argon Flash the best fake benchmaxxed model.

The post lists Opus 5.5, Sonnet 5.5 and Haiku 5.5 launches and setbacks for GPT-6.1, and says Gemini 4 Argon has only been teased, not publicly tested, so it is missing its iteration window.

A Turkish-language post complains that every other lab released a new model before Gemini 4 Argon came out.

A leak account says the Gemini 4 model codenamed Argon will not launch today, with a video but no new date.

A leak says Gemini 4 Argon could launch today or tomorrow at $4 input and $20 output, with cached input as low as $0.10/M, and that it is already in Google Cloud.

A user shared a link to a conversation with Gemini 4 Argon, saying some Pro subscribers have received early access.
