God is hungry for Context: First thoughts on o3 pro

a year ago

OpenAI reduced o3 pricing by 80% and launched o3-pro, matching GPT 4.1 pricing.
o3-pro has a 64% win rate vs o3 on human testers and performs better on reliability benchmarks.
The key to using o3-pro effectively is to treat it as a report generator, providing ample context and goals.
o3-pro excels in deep analysis and planning, offering specific, actionable insights when given sufficient context.
Integration with the real world is a challenge; o3-pro shows improvement in tool usage and environmental awareness.
o3-pro tends to overthink without enough context and is better at analysis than direct execution.
Compared to Claude Opus and Gemini 2.5 Pro, o3-pro feels superior and operates on a different level.
Prompting strategies for reasoning models remain unchanged, emphasizing context and system prompts.
o3-pro's system prompt significantly shapes behavior, more so than o3.
LLMs need to ask more questions to refine tasks before making autonomous decisions.
o3 series models are more prone to hallucinations compared to Claude or 4o, requiring thorough fact-checking.
