o3-mini is now free, and an insight into how OpenAI trains its models

There’s something about the word “free” that makes us feel warm.

Especially on a cold Monday: OpenAI’s o3-mini’s high-performance reasoning model just became free.

Yep, ChatGPT users with a free account and the API can use o3-mini. Paid users also have access and can now send 150 messages per day instead of just 50.

What to use it for: o3-mini excels at science, math, and coding queries, so it’s probably worth using for web updates, reports, predictions, etc.

It also offers flexible reasoning effort settings, is developer-friendly, and matches or exceeds the o1 model’s performance. It even outperforms GPT-4o in certain safety and jailbreak evaluations.

Speaking of evaluation…

OpenAI is experimenting with “persuasive” AI: The company uses Reddit similar to how people check r/AITA to see if they’re in the wrong.

Only in this case, ChatGPT generates responses to a r/changemyview post, and human testers evaluate its post for persuasiveness. Of course, this raises a huge question…

Why train AI chatbots to be persuasive? Supposedly OpenAI is doing this to prevent chatbots from becoming too persuasive. Right…

We’ll stick with the optimistic view and just say, we wouldn’t be surprised if this eventually shows up in OpenAI’s tools and makes chatbots and copy more compelling.
