llm-gemini 0.36 ships as Simon Willison tests Gemini 4 Carbon

llm-gemini 0.36

Simon Willison released llm-gemini 0.36 and tested Gemini 4 Carbon, which opened to everyone today. The model costs $2 per million input tokens and $10 per million output tokens at launch, with prices set to double to $4 and $20 on December 1st.

Why it matters: Willison tested map animation in Antigravity and used follow-up prompts to turn the output into a standalone HTML file with no external dependencies.
