OpenAI has introduced a new model, GPT-o1, which requires different prompting techniques compared to its predecessors like GPT-4 and GPT-4o. The new model, known for its enhanced reasoning capabilities, performs best with straightforward prompts. Traditional prompt engineering methods, such as few-shot prompting or instructing the model to 'think step by step,' may not enhance performance and can sometimes hinder it. OpenAI has released new guidelines to help users adapt to this new paradigm, including advice on using chain-of-thought prompting. An article in VentureBeat discusses these changes in detail.
