Great to see more than 230 organizations across the AI ecosystem have signed a letter supporting open weights as part of America’s AI future.
Their message: open weights enable more people to build, compete, and put AI to work.
Here’s why that matters. 🧵
Good news for anyone with too many tabs: ChatGPT is getting better around the web.

Making advanced intelligence more abundant and affordable is central to our mission to ensure AGI benefits all of humanity.
With the help of GPT-5.6 Sol, we have made leaps in efficiency.
Today, we are passing those gains on in the API with lower prices for Luna and Terra, and providing faster performance to Sol.
These updates help everyone get more useful work from every dollar and move faster when time matters.

We are committed to pushing the model frontier across cost efficiency, capability, and speed.
Starting today, we are reducing prices for GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20% , and offering a faster option for GPT-5.6 Sol in the API.
Luna and Terra’s lower prices are reflected in how usage is counted in Codex and ChatGPT Work, so your usage goes further.
At the core of our mission is working through how to ensure increasingly powerful AI benefits everyone.
We believe that, at some point in the future, AI acceleration for frontier model development may be so high that the world will need to pace the rate of AI advancement.
We hope to contribute to work led by the U.S. government, alongside other labs and the open-source community, to develop the tools and mechanisms that could make that possible.

Since launching last week, more than 230 companies and organizations from across the tech sector have signed the "Open Weights and American AI Leadership" open letter. We want to thank these partners for standing up and publicly supporting broader access to AI innovation. A special thanks to @nvidia, @a16z, and @PalantirTech for working with @Microsoft on this effort.
These signatories understand that America’s AI leadership will not depend on the success of our frontier models alone, but on our ability to build a strong, secure, and open ecosystem that diffuses AI into every sector. We look forward to continuing to work with our partners and with policymakers to build that open ecosystem in a way that benefits American businesses, empowers American workers, and strengthens the American economy.
