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

An Indonesian developer used Gemini 4 Argon via Antigravity on a Pro subscription to generate a 3D web app exploring traditional Joglo houses, with no reference assets.

Citing The Information, the post says Google is already preparing Gemini 4 Carbon with improved coding after Argon's launch, alongside new Claude and OpenAI Terra models.

A satirical post traces prompt trends to 2026, where users ask Opus 5.5 to build Opus 5.6 that out-codes Codex, out-reasons GPT-6.1 Astra and out-searches Gemini 4 Argon.

A user notes rumors that Carbon follows Gemini 4 Argon and questions the opaque naming scheme, guessing these are just internal codenames.

A user says pairing Gemini 4 Argon with Blender to build 3D worlds has become their new favorite hobby, without detailing the workflow or results.

A video post puts Gemini 4 Argon head-to-head with Claude Opus 5.5, with no written verdict in the text.

The author shares a full news-video pipeline where Gemini 4 drafts scripts and a Claude Code sub-agent adversarially reviews them, with prompts and 18 open-source style skills.

A leak claims Gemini 4 Carbon is in the works with coding on par with Opus 5.5, and Sergey Brin says Google has models several generations ahead internally.

Arena tests both Muse Wonder models on 3D scenes, animated HTML clips and website builds against Gemini 4 Argon, GPT-6 Astra and more.

A user hit an Antigravity CLI error about a missing "Barium" model, speculating it is Argon's successor or a new Flash model under A/B test, and finds Argon good at project management but unreliable on details.

A user says Gemini Argon invented his and his wife's names, birth dates, and address in an email to their accountant while handling home tax work.

A user says Argon overreaches with grand plans it can't implement, but is a fun creative collaborator; their game now has volumetric erythrocyte subsurface scattering and realtime coagulation.
