Gemini 4 Argon | First Impressions

Try the models yourself: https://arena.ai/agent Google just dropped Gemini 4 Argon — the first Gemini version-number change in a while. Peter runs it head-to-head against other frontier models on a handful of generations for a quick vibe check. The headline: Gemini 4 Argon makes the Pareto frontier at roughly a third cheaper than GPT-6.1 Sol and around 70% cheaper than Opus 5.5. Gemini 4 makes some strong generations, but results were inconsistent across prompts showing that stability is something to watch.
