OpenAI has released new o3 and o4-mini models, pushing what ChatGPT is
capable of even further forward.

FULL STORY ======================================================================o3 and o4-mini are out for Pro, Plus and Team users now, free users can try o4-mini, too They can combine and use every tool in ChatGPT's arsenal o3 and o4-mini add reasoning using images to ChatGPT's abilities

OpenAI has just given ChatGPT a massive boost with new o3 and o4-mini models that are available to use right now for Pro, Plus, Team and even free tier users.

The new models significantly improve the performance of ChatGPT, and are much quicker at reasoning tasks than the earlier OpenAI reasoning models like ChatGPT o3-mini and o1.

Most importantly, they can intelligently decide which of OpenAIs various
tools to use to complete your query, including a new ability to reason with images.

OpenAI provided a livestream for the release:

Here are the three most important changes: 1. Combining tools

Both the new reasoning models can agentically use and combine every tool within ChatGPT. That means they have access to all of ChatGPTs box of tricks including, web browsing, Python coding, image and file analysis, image generation, canvas, automations, file search and memory.

The important thing though is that ChatGPT now decides if it needs to use a tool itself based on what youve asked.

When you ask ChatGPT to do something complicated using the new models, it shows you each step it is taking, and which tool it is using, and how it arrived at that decision.

Once it has done all the research the notes on its working out process disappear and you get a report on its conclusions. 2. Better performance

The way that o3 and o4-mini can intelligently decide which tools to use is a step towards the intelligent model switching weve been promised with ChatGPT 5, when it finally arrives.

As youd expect from advanced reasoning models, the report you get at the end is extremely detailed, and contains links to all sources used.

According to OpenAI, The combined power of state-of-the-art reasoning with full tool access translates into significantly stronger performance across academic benchmarks and real-world tasks, setting a new standard in both intelligence and usefulness.

The real world result of this is that these models can tackle multi-faceted questions more effectively, so dont be afraid to ask them to perform several actions at once and produce an answer or report that combines several queries together. 3. Reasoning with images Reasoning with images in ChatGPT. (Image credit: OpenAI/Apple)

Both new models are the first released by OpenAI that will integrate uploaded images into its chain of thought. They will actually reason using the images, so for example, you could upload a picture of some cars and ask what the name and model of the cars are, then how much retail value they will hold in five years time.

This is the first time that ChatGPT has been able to integrate images into a reasoning chain and presents a real step forward for multimodal AI.

Ive tried the new models on the Plus tier and Im impressed with both the
speed and comprehensiveness of the answers to my queries. While Ive always enjoyed the depth of reasoning that the o1 and o3-mini models have provided, its always meant waiting longer for a response.

The o3 model has now become my default model to choose on Plus because its fast enough that I dont feel like Im waiting around too long for an answer, but I get a satisfying amount of detail.

In short, Im impressed. The new models feel like a natural evolution of ChatGPT into something thats smarter and more capable. I also like the way that it can decide which of ChatGPTs various tools it needs to use to provide the best answer. Trying it for yourself

Heres how to try the new ChatGPT models for yourself:

Plus, Pro and Team users will see that they can select ChatGPT o3, ChatGPT o4-mini and ChatGPT o4-mini-high from the drop-down LLM menu inside ChatGPT, and free tier users can get access to o4-mini by selecting the Reason button in the composer before submitting your query. Edu users will gain access in one week.

Theres no visual notification for free tier users that they are now using the 4o-mini reasoning model, but if you click the button and ask ChatGPT which
LLM it is using then it now says 4o-mini.

There will be a rate limit for how many times a free tier user can use the Reasoning feature, and for Plus users is much higher.

OpenAI say they expect to release o3-pro in a few weeks, with full tool support. Pro users can already access o1-pro. You may also like ChatGPT

feature, and it's just as good as ChatGPT and Google Gemini's Deep Research features Claude tipped to get its answer to ChatGPTs Advanced Voice Mode soon - is adding an AI voice to a chatbot yet another tick box exercise?
