How Do OpenAI o3 and o4 Mini Upgrades in ChatGPT Work

TL;DR

04 Mini High is the top model for coding and visual reasoning and is available on Pro and Teams plans. 03 replaces 01 as the main reasoning model, while 04 Mini offers faster responses and strong multimodal capabilities. These models support search, memory, and image analysis to enhance ChatGPT performance.

Transcript

OpenAI just released three new models inside of Chat GPT available right now. They released one called 03, 04 mini, and 04 mini high. And these are considered reasoning or thinking models. So they think in the background before they give you a response. 03 will replace 01. And if you have the pro plan, which is $200 a month, also 01 pro mode looks ... Read More

Questions & Answers

Q: What is the role of o3 in ChatGPT compared to 01

o3 replaces 01 as the newer reasoning model and is described as a background thinker that processes before forming a response, which means it handles reasoning tasks more efficiently than the old 01 model and is positioned as part of the new generation of reasoning models.

Q: How does 04 mini compare to 04 mini high in the video

04 mini is presented as a fast, capable model suitable for many tasks, while 04 mini high is depicted as the best overall option, particularly for coding and visual tasks, due to its enhanced capabilities and higher performance in benchmarks and real examples shown by the host.

Q: Which plans give access to o3 and o4 mini according to the video

The host states that these three models are available in Pro plan and Teams plan, and they should be rolling out to those plans, giving users access beyond the standard free tier.

Q: What kind of tasks demonstrate multimodal reasoning in the video

The video shows multimodal reasoning by analyzing images, performing web searches based on prompts, and integrating data from the image and external sources to answer complex questions, illustrating how the models can handle visual problems and cross-modal prompts.

Q: What is a key capability demonstrated with memory in these models

A memory capability is demonstrated where the model can access past chats to personalize responses, combining memory with search and reasoning to tailor outputs to user interests and ongoing conversations.

Q: How does the video describe the use of autonomous web search

The video demonstrates that the models can perform web searches on their own as part of the reasoning process, without requiring explicit user instructions to enable search, showcasing autonomous information gathering during tasks.

Q: What is the practical takeaway about which model to use for coding tasks

For coding tasks, the video recommends using 04 mini high as the top option due to its strong coding performance and image analysis capabilities, while acknowledging that 04 mini offers fast responses and strong multimodal features in many scenarios.

Q: How does 03 vs 04 mini performance vary by task according to benchmarks

According to benchmarks shown in the video, 04 mini generally performs very well and is top in many tests, while 03 can outperform 04 mini in some multimodal scenarios, illustrating that the best choice depends on the specific task and modality involved.

Summary & Key Takeaways

• The video explains three new models inside ChatGPT: o3, o4 mini, and o4 mini high, highlighting their reasoning capabilities and where they fit in pricing plans.

• It compares performance benchmarks showing 04 mini as a strong option and 04 mini high as the best for coding and visual tasks, with 03 as a replacement for older models.

• The host demonstrates multimodal reasoning, web search, memory features, and image analysis to showcase the models’ integrated capabilities.
