Advanced Voice is rolling out to all Plus and Team users in the ChatGPT app over the course of the week. While you’ve been patiently waiting, we’ve added Custom Instructions, Memory, five new voices, and improved accents. It can also say “Sorry I’m late” in over 50 languages.

There has been a lot of enthusiasm to try OpenAI o1-preview and o1-mini, and some users hit their rate limits quickly. We reset weekly rate limits for all Plus and Team users so that you can keep experimenting with o1.

We’re hosting an AMA for developers from 10–11 AM PT today. Reply to this thread with any questions and the OpenAI o1 team will answer as many as they can.

curious about RL given the o1 and o1-mini release? interested in the algorithms behind reasoning? reminder that @jachiam0's Spinning Up is still one of the best resources (though slightly out of date) for learning reinforcement learning. spinningup dot openai dot com!

Today we rolled out OpenAI o1-preview and o1-mini to all ChatGPT Plus/Team users & Tier 5 developers in the API. o1 marks the start of a new era in AI, where models are trained to "think" before answering through a private chain of thought. The more time they take to think, the…

Shared our GPT-4o system card today, with details of our extensive safety evaluations and mitigations implemented before deploying the model. We talk about specific risks, such as unauthorized voice generation and ungrounded inference, and how these were addressed through robust…


Consider joining @karinanguyen_’s team to align and craft our models

I’m hiring for the Model Behavior team at OpenAI! It’s my dream job at the intersection of design engineering and post-training research, and the rarest in the world ❤️ We define the core behavior of models using alignment methods such as RLHF / RLAIF to reflect fundamental…

Today we’re rolling out advanced Voice Mode in ChatGPT to small group of Plus users, all Plus users in fall. Richer and more natural real-time conversations make the technology less rigid — we’ve found it more collaborative and helpful and think you will as well.

We’re starting to roll out advanced Voice Mode to a small group of ChatGPT Plus users. Advanced Voice Mode offers more natural, real-time conversations, allows you to interrupt anytime, and senses and responds to your emotions.



Our SearchGPT prototype is now live. We’re looking for feedback as we prepare to integrate the experience in ChatGPT

We’re testing SearchGPT, a temporary prototype of new AI search features that give you fast and timely answers with clear and relevant sources. We’re launching with a small group of users for feedback and plan to integrate the experience into ChatGPT. openai.com/index/searchgp…



Cranking up the accuracy and safety of our models, while cutting down on the need for a lot of human-labeled data.

Rule-based rewards (RBRs) use model to provide RL signals based on a set of safety rubrics, making it easier to adapt to changing safety policies wo/ heavy dependency on human data. It also enables us to look at safety and capability in a more unified lens as a more capable…



You can now fine-tune GPT-4o mini. Enjoy!

Customize GPT-4o mini for your application with fine-tuning. Available today to tier 4 and 5 users, we plan to gradually expand access to all tiers. First 2M training tokens a day are free, through Sept 23. platform.openai.com/docs/guides/fi…



GPT-4o mini makes intelligence far more affordable opening up a wide range of applications. Available on API and rolling out on ChatGPT today

GPT-4o mini scores highly on textual intelligence and reasoning (82% on MMLU), math, coding, and multimodal reasoning.

As AI improves humans will need more and more help to monitor and control it. So my team at OpenAI have trained an AI that helps humans to evaluate AI! (1/5)


Very happy to have Kevin & Sarah on our team!

We are excited to welcome two leaders with the right experience, skills, and values to push the mission forward. @thefriley is joining as Chief Financial Officer, and @kevinweil as Chief Product Officer. openai.com/index/openai-w…
