  • Simon Willison’s llm-gemini 0.35 release adds support for the new Gemini 4 Argon model, highlighting its strong SVG generation capabilities, particularly for pelicans.
  • Gemini 4 Argon launches with a competitive price ($2/million input, $10/million output), matching GPT-6 Sol, but is scheduled to double in price on December 1st.
  • Despite the impending price increase, the model demonstrates “very good” cost-effectiveness on the Artificial Analysis benchmark, costing $2,407 to run and proving significantly cheaper than latest models from OpenAI, Anthropic, and Meta.
  • A key takeaway is that raw token pricing is less crucial than “how many tokens a model takes to achieve a goal within an agentic harness,” a metric where Argon currently shows strong performance.
