  llm-geminiLLM CLI plugin — calls Gemini models from `llm`

  Simon Willison's llm CLI can now call Google's new Flash model through the Gemini plugin. Small update, but useful if your scripts already depend on llm.

  • —llm-gemini now exposes gemini-3.5-flash, so existing llm CLI workflows can test the model without custom API glue.
  • —Scope is one model alias in a plugin release. This is practical plumbing, not a new app-building capability by itself.
  • —Best fit is quick model comparison for summaries, extraction, and generation jobs already wired around Simon Willison's llm ecosystem.

  `Gemini 3.5 Flash` ships broadly with a 3-6x price jump

  90radar

  Google is putting the new default-grade model into Search, Gemini, Android Studio, and the API. The API math changed: high-output features need a fresh margin check.

  • —Model ID is gemini-3.5-flash; it supports 1,048,576 input tokens and 65,536 output tokens. Strong fit for long-context document flows.
  • —Pricing is $1.50/M input and $9/M output, 3x 3 Flash Preview and 6x 3.1 Flash-Lite. Flash is no longer the obvious cheap default.
  • —Interactions API is in beta with server-side history management, echoing the Responses API pattern. Agent backends may get simpler state handling.
  • —No computer-use feature in this release. If your workflow depends on browser/desktop control, this is a model upgrade, not a full agent-runtime replacement.
  • —3.5 Pro is slated for next month, likely pricier. Build model routing now instead of hard-coding one Gemini tier.

  Google adds `$100 AI Ultra` tier to `Google AI` subscriptions

  60radar

  Google is expanding paid AI access beyond Plus and Pro. The new high-end tier signals stronger feature gating, but API impact is unclear.

  • —AI Ultra is priced at $100; useful only if the included model or product limits beat existing Pro access.
  • —Google AI Plus, Pro, and Ultra all get new features and benefits, but the excerpt gives no quota or model details.
  • —This is subscription pricing, not confirmed API pricing. Treat it as a product-access signal, not a backend cost change.
