Report a correction

This entry is a serving variant of Google: Gemini 3.5 Flash. A variant shares its base model's tokenizer by construction, so the measurement lives on the base record and this page inherits it.

Identity statement

Google: Gemini 3.5 Flash (batch) is Google's model. Its measured tokenizer sits with the Gemini group, which is evidence that it builds on the Gemini tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against Google's authorship of the model itself.

What we checked

Four different kinds of evidence, and what each one showed

We checked	What we found	Where it came from
How it counts tokens	Not measured yet	we measured it
How its API is set up	Set up identically to 2 other listings, field for field	api_40858f91
How much it can read and write	Reads up to 1,048,576 tokens at once, writes up to 65,536	its own listing
Whether it thinks before answering	Always reasons, and cannot be turned off, at high, medium, low, minimal, medium by default	its own listing
