Billions of tokens later: Gemini 4 ≈ Opus 4.8, worse at writing and agentic loops

After burning billions of tokens on data/code/analysis tasks, Hrishi concludes Gemini 4 ≈ Opus 4.8—a floor-of-capability comparison. Gemini 4 is significantly better multimodally, but weaker at agentic looping (tool call fidelity) and disappointing at writing compared to hoped-for Gemini 2.5/GPT-4.5 creativity. He caveats it's a near-launch model vs. a heavily optimized competitor. (Unverified model names; treat as credible leak/early access.)
