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

Japanese AI chat platform CaveDuck is running a Halloween promotion that drops Gemini 4 Argon from 120 to 90 wings and adds creator incentives through October 26.

Philipp Schmid confirms that Gemini 4 Argon is now available to Google AI Pro subscribers.

The author notes that AI versions change daily, mentions Google's Gemini 4 Argon launch, and discusses XO Market's prediction market for the strongest AI company of the month.

A Spanish-language post describes Google's free agentic tool Deep Review, powered by Gemini 4 Argon, which reviews manuscripts twice a week for logic and calculation errors and checks references.

The author used Gemini 4 Argon to build a full Asuka-period Japanese pagoda temple in Blender and render it in Cycles, calling its 3D modeling precision remarkable.

The poster says he has a startup idea he won't share because people using Gemini 4 Argon would have it live within two hours.

A Japanese user continues a conversation with Gemini 4 Argon about next year's AI bubble risk, especially fearing a semiconductor memory oversupply could hit Japan's Rapidus at the worst time.

Meta released Muse Spark Open, an 816B-parameter open-weights model with 42B active parameters built for coding and agents, tuned to run on two linked Mac Studios; in Cursor's benchmark, Muse Wonder scored 46.1% versus Gemini 4 Argon's 52.8%.

Gemini 4 Argon, previously limited to Ultra subscribers, is now available to Google AI Pro users in Antigravity with High effort settings and a separate weekly quota isolated from 3.8 Flash and Claude/GPT, though users report it drains fast.

A user says Gemini 4 Argon with memory can guess intent from a single word and is excellent for daily use, but worries it may迎合 technical architecture preferences and lose neutrality.

Argon is reportedly open only to paid Pro subscribers, and the author says the bottleneck is inference capacity rather than pricing, urging Google to scale up for real-world workflow testing.

A Japanese post shares a cost-saving flow: draft the design in Planning mode with Gemini 4 Argon, implement quickly with Gemini 3.8 Flash, then finish and fix bugs with Claude Sonnet/Opus 5.5.
