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

A user says Opus and Sonnet 5.5 quotas in Antigravity will be very tight, and that if Gemini 4 Argon isn't good enough, buying Claude directly is the better option.

A user shares a "self portrait" video generated with Gemini 4 Pro, showing the model's output on self-image style video generation.

Antigravity is adding Claude Opus 5.5 and Sonnet 5.5 for Pro and Ultra users while removing third-party access to GPT-OSS 120B, which the poster reads as a sign that Gemini 4 Argon is close.

Antigravity's paid tiers now include Claude Opus 5.5 and Sonnet 5.5, and the poster argues that adding Gemini 4 Argon would make them hard to beat.

The Antigravity editor now includes Claude Opus 5.5 and Sonnet 5.5, with Gemini 4 Argon said to be coming soon, and the post asks whether users will switch.

A short video labeled only "GEMINI 4 PRO" that shows the model's actual output.

A video shows Gemini 4 Argon running a Temple Run-style game as a hands-on demo.

A user says Antigravity added Opus 5.5 and Sonnet 5.5 days after they asked, but Gemini 4 Argon (or Pro) is still missing from the model list.

Antigravity added Opus 5.5 and Sonnet 5.5 to its Pro and Ultra tiers and will remove older models on Nov 2, while Gemini models stay and Gemini 4 Argon is not yet listed.

A leak says Antigravity will bring in Opus 5.5 and Sonnet 5.5, packaged with Gemini 4 Argon in the Ultra subscription.

He argues Gemini 4.0 Pro is still frontier intelligence even at 95% of Astra's performance while costing 5x less, putting Google ahead of open source for the first time.

Opus 5.5 and Sonnet 5.5 are said to arrive on Antigravity Pro and Ultra, available to developers alongside Gemini 4 Argon.
