  • Simon Willison released llm-gemini 0.34, introducing support for Google’s new gemini-3.8-flash model, which offers low, medium, and high “thinking levels.”
  • The gemini-3.8-flash model is highlighted for being “fast, cheap, and competent” at tasks like generating HTML and JavaScript, demonstrated by creating a “cool thing in HTML” in 13 seconds for 1.8 cents.
  • Willison also used Gemini 3.8 Flash with his llm-coding-agent to add support for rendering HTML blocks in Markdown via sandboxed iframes within his markdown-svg-renderer tool.
  • The update underscores the practical utility of Gemini Flash models for rapid, cost-effective code generation and their potential for integration into development workflows to enhance existing tools.
