Note that (in the first test, the only one where output length is reported), Gemini Pro returned more than 3x the amount of text, at less than 2x the amount of time. From my experience with Gemini, that time was probably mainly spent on thinking, length of which is not reported here. So looking at pure TPS of output, Gemini is faster, but without clear info on the thinking time/length, it's impossible to judge.

if they left them both on defaults, flash is thinking-by-default and sonnet 4 is no-thinking-by-default

output tokens must be generated in order (autoregressive decoding), inputs don’t have that constraint, so prefill is parallel, with stronger kernels, KV-cache handling, and batching, Claude can outrun Gemini.

> Claude’s overall response was consistently around 500 words—Flash and Pro delivered 3,372 and 1,591 words by contrast.

It isnt clear from the article whether the time they quote is time-to-first-token or time to completion. If it is latter, then it makes sense why gemini* would take longer even with similar token throughput.

From my experience. Gemini is REALLY bad about context blending. It can't keep track of what I said and what it said in a conversation under 200K tokens. It blends concepts and statements up, then refers to some fabricated hybrid fact or comment.

Gemini has done this in ways that I haven't seen in the recent or current generation models from OpenAI or Anthropic.

It really surprised me that Gemini performs so well in multi-turn benchmarks, given that tendency.

The series is 1,084,170 words. At let's say 1.4 tokens per word, this would not fit, but it is getting close.

The entire HP series is about one million words.

Anthropic also uses TPUs for inference.

I’ve not experimented with the recent models for this but older Gemini models were awful for this - they’d lie about what I’d said or what was in their system prompt even with short conversations.

It's 2M tokens for Gemini.

Harry Potter and the Order of Phoenix alone is 400K tokens.

And takes up a proportional width of everyone's bookshelves along side the others.

How do they do if you test[1] them for attention deficit disorder?

Curious, I found an epub, converted it to a txt, and dumped it into the Qwen3 tokenizer. It yielded 359,088 tokens, end to end.

Using the GPT-4 tokenizer (cl100k_base) yields 349,371 tokens.

Recent Google and Anthropic models do not have local tokenizers and ridiculously make you call their APIs to do it, so no idea about those.

Just thought that was interesting.

That was previous iterations, 2.5 is 1 million context window

https://ai.google.dev/gemini-api/docs/models (context window is details under model variant section with + signs)

They were meant to crank 2.5 to 2 million at some point though, maybe waiting now till 3?

Google provides them.

I mean the Harry Potter books are 2M tokens.

Funny you mention this, I literally just got done loading the context window of AI studio up for an hour doing some prototyping and then was frustrated when I couldn’t see where I was at from billing (knew it couldn’t be that much, but I still like to know).

I assumed because I’m on paid tiers it would still cost behind a certain usage amount, but I guess not.

Maybe consuming the resources internally.

Can you opt out of them training on your data in that free tier?

Geminis free tier allows maybe 5 messages on average, for 2.5 pro at least and this is not usable.

I’m using Claude Pro for daily driver and Gemini / ChatGPT free tiers.

If you have cloud billing enabled you can still use it for free and they say they don't train on it. https://ai.google.dev/gemini-api/docs/billing#paid-api-ai-st...

Not on ai studio.

You are clearly confirming my comment above.

How?

Read the text, click the links, let it sink in

I did that, and I assume GP did as well.

There is some information that you assume to have shared that we are not picking up on.

May be ask your favorite AI about what you are missing. Or may be ask using AI studio as that won't rate limit you ;)
