OpenAI o1 represents the company's first series of reasoning-focused language models that can be accessed through their API platform. Currently in beta, it requires Tier 5 API access level and includes two model variants: o1-preview for tackling hard problems using broad general knowledge, and o1-mini as a faster, more affordable version optimized for coding, math, and science tasks. The models are trained using a new optimization algorithm and reinforcement learning approach, moving beyond simple pattern matching to enable more sophisticated reasoning capabilities.

OpenAI o1 is a new series of reasoning-focused AI models available through the API, featuring o1-preview and o1-mini variants. These models excel in complex reasoning tasks, particularly in math, science, and coding, using a chain-of-thought approach that enables deeper thinking before generating responses. Currently in beta, API access requires Tier 5 usage level with a rate limit of 20 requests per minute. Advanced Reasoning Capabilities: Utilizes chain-of-thought reasoning to tackle complex problems, outperforming GPT-4o in areas like math and coding Two Model Variants: Offers o1-preview for broad knowledge tasks and o1-mini for specialized coding, math, and science tasks requiring less general knowledge Specialized Training: Trained with a new optimization algorithm and reinforcement learning approach, moving away from traditional pattern-mimicking methods Beta API Access: Limited access through API requiring Tier 5 usage level with 20 RPM rate limit and specific implementation requirements

Complex Problem Solving: Solving intricate mathematical problems and scientific calculations requiring multi-step reasoning Code Development: Generating and debugging complex code solutions with improved accuracy and reasoning capabilities Scientific Research: Analyzing and solving PhD-level science questions with performance exceeding human experts Technical Documentation: Creating detailed technical documentation and explanations with logical reasoning and step-by-step approaches

Superior reasoning capabilities compared to previous models Excellent performance in specialized tasks like coding and math More accurate results in complex problem-solving scenarios

Limited API access (Tier 5 only) Slower response times compared to GPT-4o Currently lacks features like function calling, streaming, and system messages Higher operational costs

Check API Access Requirements: Verify that your OpenAI account is in Tier 5 usage level (requires $1,000 paid and 30+ days since first successful payment). Currently o1 models are only available to Tier 5 API users. Generate API Key: Log in to the OpenAI platform and generate an API key from your account dashboard if you haven't already. Install OpenAI SDK: Install the OpenAI Python package using pip: 'pip install openai'. Make sure you have version 0.0.59 or greater to use o1 models. Initialize OpenAI Client: Import and initialize the OpenAI client with your API key: 'from openai import OpenAI; client = OpenAI(api_key='YOUR_API_KEY') Choose o1 Model: Select either o1-preview (for complex reasoning with broad knowledge) or o1-mini (faster/cheaper version for coding/math/science) based on your needs. Make API Request: Create a completion request specifying the o1 model and your prompt: 'completion = client.chat.completions.create(model='o1-preview', messages=[{'role': 'user', 'content': 'Your prompt here'}])' Handle Response: Access the model's response from completion.choices[0].message.content. Note that o1 models currently have a rate limit of 20 requests per minute. Consider Limitations: Be aware that o1 API currently lacks features like function calling, streaming, and system messages. OpenAI is working to add these features in future updates.
