Google Gemini 2.5 Professional-Exp: The UI specialist with identification points
Google’s Gemini 2.5 launch ships a one-million-token context (two million promised) and is presently free to make use of in lots of locations (I’ve but to be charged for API calls).

Be careful for: Assured however flawed API calls and hallucinated libraries. Double-check any library variations it cites.
