Sam Altman, CEO of
OpenAI, stated that the company will release an open-weight reasoning language model, a significant development since GPT-2. He also took a jab at Meta's licensing requirements for its open-source models in a post on X.
“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: https://vct.ikan3.com/3sw659_9cmszrqulmse
we are excited to make this a very, very good model!” he said in a tweet.
Difference between open-weight and open-source models
An open-weight language model is characterised by the public availability of its trained parameters, or weights. This accessibility allows developers to analyse and fine-tune the model for specific applications without the need for the original training data.
“We still have some decisions to make, so we are hosting developer events to gather feedback and later play with early prototypes,” Altman stated.
This announcement follows Altman's statement in February regarding the company's plans to simplify its AI product offerings as part of a newly outlined roadmap for their latest models.
It is important to distinguish these language models from open-source models, which provide access to the complete source code, training data and methodologies. For example, Meta’s Llama-2 LLM that is available for all developers for free, except for companies that have more than 700 million daily users.
Altman makes fun of Meta’s 700 million daily users ‘rule’
According to Altman's post on X, the company plans to engage with developers to determine how to maximise the utility of the open-weight language model. The initial developer event is scheduled to take place in San Francisco within the coming weeks, with subsequent sessions planned for Europe and the Asia-Pacific region.
In a separate post, he emphasised on one “silly” thing that the company will not do.
“we will not do anything silly like saying that you cant use our open model if your service has more than 700 million monthly active users. we want everyone to use it!” Altman said, in a reference to Meta’s usage restrictions, including license fees for developers exceeding 700 million daily users and a ban on using Llama to train other language models.
Altman also announced that ChatGPT's new image generator is now rolled out to all free users.
