We've been having trouble telling if people are using the same product ever since Chat GPT first got popular. The had a free model and a paid model, that was it, no other competitors or naming schemes to worry about, and discussions were still full of people talking about current capabilities without saying what model they were using.
For me, "gemini" currently means using this model in the llm.datasette.io cli tool.
openrouter/google/gemini-3-pro-preview
For what anyone else means? If they're equivalent? If Google does something different when you use "Gemini 3" in their browser app vs their cli app vs plans vs api users vs third party api users? No idea to any of the above.
I hate naming in the llm space.
FWIW i’m always using 5.1 Thinking.
