It’s been awesome to watch the adoption of our o1 and o3‑mini models. We’ve just published a new guide on reasoning best practices, with real-world tips from some of the best AI founders using them in production. What else can we ship to help you build?

GPT-5 o-series API access with advanced reasoning capabilities
By
–
We’ll keep exposing frontier capabilities via the API for developers! You’ll still have access to advanced reasoning and all the knobs you need—like a “reasoning effort” parameter—when the o-series is part of the broader GPT-5 system.

API Platform Supports o3 Reasoning with GPT-5 System
By
–
Our developer platform remains a top priority, and our API will support o3 reasoning capabilities! Yes, we’ll keep providing all the controls you need—like a “reasoning effort” setting—so you can tap into every capability and tool directly from a single GPT-5 system. Stay tuned!

OpenAI Reveals GPT-4.5 and GPT-5 Model Roadmap Plans
By
–
Telegraphing our @OpenAI model roadmap: • GPT-4.5 is next, our final non-chain-of-thought model
• GPT-5 will merge our GPT family and the o-series (including o3), enabling systems that can use all our tools and reasoning -

OpenAI o3-mini Surpasses o1-mini in Codeforces Competitive Programming
By
–
On Codeforces competitive programming, @OpenAI o3-mini achieves progressively higher Elo scores with increased reasoning effort, all outperforming o1-mini. With medium reasoning effort, it matches o1’s performance.

OpenAI o3-mini: Faster, cheaper model for coding and agentic apps
By
–
Welcome, @OpenAI o3-mini! A fantastic model for coding and building agentic apps, complete with function calling, Structured Outputs, and streaming. It outperforms o1 on medium/high reasoning tasks, is much faster, and costs 93% less. Can’t wait to see what you build! https://
