1. Notes on OpenAI’s new o1 chain-of-thought models
Total comment counts : 61
Summary
On September 12, 2024, OpenAI unveiled two new models, o1-preview and o1-mini, aimed at enhancing reasoning capabilities over previous models like GPT-4o. These models focus on taking more time to think before responding, utilizing a reinforcement learning approach to improve the “chain of thought” mechanism. This enables them to handle complex prompts by breaking down tasks and refining strategies over time.
While o1 models are designed for deep reasoning and longer response times, models like GPT-4o remain preferable for tasks requiring image inputs or faster responses. A notable feature is the introduction of “reasoning tokens,” which enhance performance but remain invisible in API responses, adding a level of complexity in billing and usage. OpenAI recommends limiting extraneous context in retrieval-augmented generation to streamline responses.
Importantly, the reasoning tokens are hidden to maintain model safety and compliance with policy rules, preventing exposure of intermediate thought processes. This decision reflects OpenAI’s focus on ensuring user safety and competitive positioning.
