Study Notes

OpenAI's New Models Overview

OpenAI introduced two new models: o1-preview and o1-mini, previously rumored as "strawberry."
These models offer trade-offs, focusing on improved reasoning at the cost of performance and speed compared to GPT-4o.

Chain of Thought Training

New models encourage extended thinking time before generating responses, aligning with the chain of thought prompting pattern.
The training leverages a large-scale reinforcement learning algorithm to enhance productive thinking.
Performance of o1 models improves with increased reinforcement learning and extended thinking time.

Model Learning Dynamics

o1 learns to refine thinking strategies, recognize and correct errors, and decompose complex tasks into more manageable parts.
Enhanced reasoning allows better handling of complicated prompts that involve backtracking and deeper thought processes.

API Details and Trade-offs

o1 models cater to applications requiring in-depth reasoning but can tolerate longer response times.
Access to o1-preview and o1-mini is limited to tier 5 accounts with a minimum spend of $1,000 on API credits.
Models do not support system prompts, streaming, batch calls, tool usage, or image inputs.
Response times vary significantly based on the complexity of reasoning involved, ranging from seconds to minutes.

Reasoning Tokens and Output Limits

Introduction of "reasoning tokens," which are calculated as output but not visible in results, plays a crucial role in model functionality.
For optimal use, OpenAI recommends budgeting approximately 25,000 reasoning tokens for suitable prompts.
Output token limits have increased for o1-preview (32,768 tokens) and o1-mini (65,536 tokens), compared to previous limits of 16,384 tokens for GPT-4o models.

Hidden Reasoning Tokens

Reasoning tokens remain invisible in the API, meaning users are charged for them without direct visibility in responses.
This approach is designed to provide more insight into the model's internal processing without revealing overt details.

Retrieval-Augmented Generation (RAG) Recommendations

In RAG, advice has shifted to limit contextual information to the most relevant data to prevent complicating the model's output.
This contrasts with the traditional method of including extensive relevant documents.
