September sponsors-only newsletter
Simon Willison's September newsletter covers Fable-class model growth and an LLM pricing war
Simon Willison teases his September sponsors-only newsletter, which touches on Fable-class model expansion, an ongoing AI pricing war, and LLMs making inroads into mathematics. However, the actual content is paywalled, so no substantive claims or data are available from this post. As a teaser with no extractable signal, it carries low newsletter value on its own.
