OpenAI launches o3-mini, its latest reasoning model that the company says is largely on par with o1 and o1-mini in capabilities, but runs faster and costs less

OpenAI on Friday launched a new AI “reasoning” model, o3-mini, the newest in the company's o family of reasoning models.

TechCrunch 2025-02-01 Kyle Wiggers

Context & Ripple Effects

OpenAI had previewed o3 and o3-mini as models designed to “think” before answering, extending the trade-offs introduced by its earlier o1 line between stronger reasoning and higher cost or latency. The launch turns that previously signaled product direction into an available lower-cost tier.

The accompanying decision to give free ChatGPT users access to the model family marks a shift from a specialist capability toward broader distribution: free users can now try OpenAI reasoning models.

First-order effects

OpenAI gains a faster, cheaper reasoning-model option positioned near o1 and o1-mini capability, giving ChatGPT and developer use cases a lower-cost route to this class of output.
Users who previously had to weigh o1’s reasoning gains against its cost and performance trade-offs get a more economical choice; free ChatGPT access broadens the immediate audience for the capability.

Second-order effects

Competing model providers face greater pressure to pair reasoning performance with lower latency and price, rather than treating advanced reasoning as a premium-only feature.
For AI teams, model selection becomes more granular: a lower-cost reasoning tier can shift workloads that were uneconomic under the earlier o1 cost-and-performance trade-offs.

Third-order effects

If successive releases keep bringing reasoning capability closer to general-purpose model economics, differentiation will move from merely offering reasoning to delivering the best cost per useful task and reliable deployment controls.
A broader user base for reasoning models may accelerate product experimentation, while making inference cost management a more central constraint for providers and enterprise buyers.

The trend: Reasoning models are becoming a tiered, increasingly mass-market product category in which speed and inference economics matter alongside benchmark capability.

Thinking tokens are charged as output tokens (and count towards the output limit) but are completely invisible in the API - you don't even get a summary of them
@simonwillison.net Simon Willison on bluesky
I think the most notable things about o3-mini may be the price - less than half that of GPT-4o - and the output length limit — Its output limit is 100,000 tokens (input is 200,000) - compared to 16,000 for GPT-4o and just 8,000 for both R1 and Claude 3.5
@marypcbuk Mary Branscombe on bluesky
all the AI companies who have been making DeepSeek style smaller models but not releasing them (either to avoid undermining their high end models or because customers actually prefer their high end models) will now be flooding the zone. good luck working out which one best solves…
@parkerortolani.com Parker Ortolani on bluesky
DeepSeek's emergence is *hopefully* going to unleash and even greater era of innovation in new software and hardware. You think Google, OpenAI, and Anthropic have been moving fast these past few years? You just wait. The war for AI supremacy is on. [embedded post]

o3-mini is out! smart, fast model. available in ChatGPT and API. it can search the web, and it shows its thinking. available to free-tier users! click the “reason” button. with ChatGPT plus, you can select “o3-mini-high”, which thinks harder and gives better answers.

Wait, are you telling me that Sam ... lied?
@jadecole2112 Jade Cole on x
@daaaaashr ... Some folks are showing their own tests that it's about the same or worse than o1 for some tasks. This after OpenAI said this new drop would be “head and shoulders” above the state of the art models.
@polynoamial Noam Brown on x
We at @OpenAI are proud to release o3-mini, including for the FREE tier. On many evals it outperforms o1. We're shifting the entire cost‑intelligence curve. Model intelligence will continue to go up, and the cost for the same intelligence will continue to go down. [image]

OpenAI o3-mini is a good model, but DeepSeek r1 is similar performance, still cheaper, and reveals its reasoning. Better models will come (can't wait for o3pro), but the “DeepSeek moment” is real. I think it will still be remembered 5 years from now as a pivotal event in tech

the fact that o3-mini has a 100,000 token output length, and that output length is so much larger in comparison to previous models lends a lot of credence to Ben's idea that the ‘o’ series reasoning models are best seen as ‘brief’ generators rather than chatbots [image]
