Gemini 4 Argon: Built to solve your hardest problems

Key points
  • Available now via the API in AI Studio and Gemini platform, plus Google AI Ultra and Pro subscriber access in the Gemini app.
  • Introductory pricing is $2 per million input tokens and $10 per million output tokens, with cached input 95% off.
  • Google says Argon ranks #1 on the Vals Index, which measures performance across finance, coding, legal and tax work.
  • Google reports Argon helped its own teams raise agentic code submissions by more than 35% in Antigravity.

Why it matters for marketers: Content and marketing teams using Gemini tools get a model Google positions for multi-step professional work, at a stated introductory price, though the Vals ranking is Google's own report.

Meta releases its first frontier model, Muse Wonder

Key points
  • Muse Wonder costs $4 per million input tokens and $20 per million output tokens via the Meta Model API.
  • Wonder Full is limited to Muse Code subscribers and is not served through the API.
  • Meta says Wonder scores higher on MemoryBench than Fable, Opus, or Astra, per its own testing.
  • Models were reportedly trained at Meta's Prometheus data center in central Ohio.

Why it matters for marketers: Content teams building long-running assistants may get a stronger memory option, but pricing is comparable to rival frontier models and Meta's benchmark claims are self-reported.
