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

GBENCH posts GPT-6.1 Terra coding results placing it between Gemini 4 Argon and Claude Opus 5.5, and discusses coding-assistant usability differences.

A developer lists what one Gemini API key enables for agents—image/video understanding, audio, generation, TTS, cheap transcription and classification—and says Argon 4 is creative and uncorrelated with Claude/OpenAI models, near frontier but still behind Opus 5.5 for daily use.

Same prompt to Claude Opus 5.5, GPT-6 Astra, Grok 4.7 and Gemini 4 Argon to build a lobe pump; the author says Gemini's four-blade rotors look like propellers.

On the same Night Train prompt, Gemini 4 Argon finished in 4m20s for $3.40 — faster than Terra but judged to look like a mobile game.

Gemini 4 Flash is reportedly reaching ~300 tokens/sec on LMArena, which the author says would be a major edge if it delivers Argon-level intelligence at Flash pricing.

Opus 5.5, Sol 6.1 and Gemini 4 Argon all sit on the Pareto frontier, but Opus is more read-efficient while Argon burns more output tokens to reach the same score.

FrontierCode 2.0 separates model tiers more sharply: Muse Wonder 1.0 and Gemini 4 Argon top DeepSWE v1.1 but land mid-pack on FrontierCode 2.0.

A joke thread noting Anthropic names models after literature, OpenAI after astronomy, Google after chemical elements such as Argon and Hydrogen, and DeepSeek after dates.

A creator recreated a Seedance 2.5 fantasy baby-dragon video with Gemini Argon as a side-by-side video generation demo.

The poster notes DeepSeek runs around 400 tokens/s and MiniMax M3.1 Flash near 1000 tps, so the real question is whether Gemini 4 Flash can outperform both on actual quality.

The post compares Argon batch at $1/$5 per 1M tokens with Opus 5.5 standard at $4/$20 and walks through a 50M-in, 10M-out migration cost example.

A user comparing the same prompt and directory says Gemini 4 Argon finds more accurate sources and explains them more clearly than fable-5.1 for chatbot and consulting agent use.
