Funny you should say that. Google just announced today that they are giving all college students one year of free Gemini advanced. I wonder how much that will actually move the needle among the youth.

And every professor just groaned at the thought of having to read yet another AI-generated term paper.

Take-home assignments are basically obsolete. Students who want to cheat, can do so easily. Of course, in the end, they cheat themselves, but that's not the point.

Absolutely decimated on metrics by o4-mini, straight out of the gate, and not even that much cheaper on output tokens (o4-mini's thinking can't be turned off IIRC).

Not sure "decimated" is a fitting word for "slightly higher performance on some benchmarks".

66.8% error rate reduction for o4-mini on AIME2025, and 21% error rate reduction on MMMU isn't "slightly higher". It'll be quite noticeable in practice.

Nobody has really talked about what I think is an advantage just as powerful as the custom chips: Google Books. They already won a landmark fair use lawsuit against book publishers, digitized more books than anyone on earth, and used their Captcha service to crowdsource its OCR. They've got the best* legal cover and all of the best sources of human knowledge already there. Then Youtube for video. The chips of course…

The amount of text in books is surprisingly finite. My best estimate was that there are ~10¹³ tokens available in all books ( https://dynomight.net/scaling/#scaling-data ), which is less than frontier models are already being trained on. On the other hand, book tokens are probably much "better" than random internet tokens. Wikipedia for example seems to get much higher weight than other sources, and it's only ~3×10¹⁰…

We need more books! On it…

One hidden note from Gemini 2.5 Flash when diving deep into the documentation: for image inputs, not only can the model be instructed to generated 2D bounding boxes of relevant subjects, but it can also create segmentation masks! https://ai.google.dev/gemini-api/docs/image-understanding#se... At this price point with the Flash model, creating segmentation masks is pretty nifty. The segmentation masks are a bit of a g…

Wait, did they just kill YOLO, at least for time-insensitive tasks?

If the battle was between Altman and Pichai I'd have my doubts. But the battle is between Altman and Hassabis. I recall some advice on investment from Buffett regarding how he invests in the management team.

Could you please expand, on both your points?

It is more gut feel than a rational or carefully reasoned argument.

I think Pichai has been an exceptional revenue maximizer but he lacks vision. I think he is probably capable of squeezing tremendous revenue out of AI once it has been achieved.

I like Hassabis in a "good vibe" way when I hear him speak. He reminds me of engineers that I have worked with personally and have gained my respect. He feels less like a product focused leader and more of a research focused leader (AlphaZero/AlphaFold) which I think will be critical to continue the advances necessary to push the envelope. I like his focus on games and his background in RL.

Google's war chest of Ad money gives Hassabis the flexibility to invest in non-revenue generating directions in a way that Altman is unlikely to be able to do. Altman made a decision to pivot the company towards product which led to the exodus of early research talent.

I spotted something interesting in the Python API library code:

https://github.com/googleapis/python-genai/blob/473bf4b6b5a6...

  class ThinkingConfig(_common.BaseModel):
      """The thinking features configuration."""
   
      include_thoughts: Optional[bool] = Field(
          default=None,
          description="""Indicates whether to include thoughts in the response. If true, thoughts are returned only if the model supports thought and thoughts are available.
        """,
      )
      thinking_budget: Optional[int] = Field(
          default=None,
          description="""Indicates the thinking budget in tokens.
          """,
      )
That thinking_budget thing is documented, but what's the deal with include_thoughts? It sounds like it's an option to have the API return the thought summary... but I can't figure out how to get it to work, and I've not found documentation or example code that uses it.

Anyone managed to get Gemini to spit out thought summaries in its API using this option?

They should just get AI to mark them. I genuinely think this is one thing AI would do better than humans.

Grading papers definitely requires intelligence.

Note sure why their comment was downvoted. Google the names. Hassabis runs DeepMind at Google which makes Gemini and he's quite brilliant and has an unbelievable track record. Buffet investing in teams points out that there are smart people out there that think good leadership is a good predictor of future success.

Google making Gemini 2.5 Pro (Experimental) free was a big deal. I haven't tried the more expensive OpenAI models so I can't even compare, only to the free models I have used of theirs in the past. Gemini 2.5 Pro is so much of a step up (IME) that I've become sold on Google's models in general. It not only is smarter than me on most of the subjects I engage with it, it also isn't completely obsequious. The model push…

This comment is exactly my experience, I feel like as if I had wrote it myself.

It must have something to do with the way your wife is prompting. I've noticed this with my friends too. I usually get working code from Gemini 2.5 Pro on the first try, and with a couple of follow-up prompts, it often improves significantly, while my friends seem to struggle communicating their ideas to the AI and get worse results. Good news: Prompting is a skill you can develop.

Or we can just learn to write it ourselves in the same amount of time /shrug

If you're going to need scripts like that every week - sure. If you need it once a year on average... not likely. There's a huge amount of things we could learn but do them so infrequently that we outsource it to other people.
