OpenAI Updates Chain of Thought for o3-mini AI Model
In Response to Rival’s Pressure, OpenAI Changes the Way o3-mini Communicates its Step-by-Step "Thought" Process
OpenAI, a leading AI research organization, is modifying the way its newest AI model, o3-mini, communicates its step-by-step "thought" process in response to pressure from rivals, including Chinese AI company DeepSeek. The company is introducing an updated "chain of thought" that shows more of the model’s "reasoning" steps and how it arrives at answers to questions.
Updated Chain of Thought for ChatGPT Users
The updated chain of thought will be available to free and paid users of ChatGPT, OpenAI’s AI-powered chatbot platform. Subscribers to premium ChatGPT plans who use o3-mini in the "high reasoning" configuration will also see this updated readout. According to OpenAI, the updated chain of thought will make it easier for users to understand how the model thinks, providing more clarity and confidence in its responses.
How the Update Works
The update introduces an additional post-processing step where the model reviews its raw chain of thought, removing any unsafe content and simplifying complex ideas. This step also enables non-English users to receive the chain of thought in their native language, making it more accessible and friendly.
Rationale Behind the Update
OpenAI’s decision to update the chain of thought is partly due to competitive reasons. DeepSeek’s R1 model, a "reasoning" model similar to o3-mini, reveals its full thought process, which many AI researchers argue is the preferred approach. The reasoning steps deliver a better user experience in certain situations, helping to indicate when the model might be on the right or wrong track.
Background on o3-mini
o3-mini is a "reasoning" model that thoroughly fact-checks itself before giving out results. This approach helps the model avoid some of the pitfalls that normally trip up models. The trade-off is that reasoning models take a little longer to arrive at solutions – typically seconds to minutes longer.
Reaction to the Update
Noam Brown, a researcher, tweeted about the update, saying, "When we briefed people on 🍓 before o1-preview’s release, seeing the CoT live was usually the ‘aha’ moment for them that made it clear this was going to be a big deal. These aren’t the raw CoTs but it’s a big step closer and I’m glad we can share that experience with the world."
