also odd that the new york times seems to be the only major news outlet silent about monday's landmark ruling protecting training as “exceedingly transformative” fair use 🤔.

AI privacy is critically important as users rely on AI more and more. the new york times claims to care about tech companies protecting user’s privacy and their reporters are committed to protecting their sources. but they continue to ask a court to make us retain chatgpt.

GPT-4.1 is our newest family of GPT series models - available in the API today, including 4.1 mini and nano. 4.1 takes big steps forward in coding, instruction following, and context length up to 1M. it's 26% less expensive than 4o, and prompt caching discounts are now 75%; 4.1.

Thanks @openai for having me on the GPT-4.1 announcement livestream this morning! . We've been testing 4.1 for the past couple weeks -- it's really good. And now, it's available in Windsurf. It's free for all users this week and will be discounted after. Go give it a try!

Before launching this model, we’d love your feedback to help shape our approach, and to ensure this model genuinely meets your needs. If you’re a developer building on open models, or even if you’re just interested in this topic, we’d love to hear from you:.

Our goal with this open model is to address exactly that: expanding developer access to powerful AI, while continuing to maintain high standards for safety and responsible deployment. We think this is important for both the US and the world, especially as AI becomes foundational.

As models improve, there is more and more demand to run them everywhere. Through conversations with startups and developers, it became clear how important it was to be able to support a spectrum of needs, such as custom fine-tuning for specialized tasks, more tunable latency,.

Primarily because developers, along with many of our business and government customers, have asked for it. We serve millions of developers every day – many rely on a mix of proprietary and open models to build AI products. We’ve provided frontier models through our API since.

We’re planning to release a very capable open language model in the coming months, our first since GPT-2. Why are we doing this, and why now? More importantly – how can you help shape it? 🧵.

TL;DR: we are excited to release a powerful new open-weight language model with reasoning in the coming months, and we want to talk to devs about how to make it maximally useful: we are excited to make this a very, very good model!. __. we are planning to.
