THE VIRTUAL CELL WILL BE MORE LIKE GWAS THAN ALPHAFOLD

A virtual cell is a model that lets researchers model diseases and treatments. Tied with the push for virtual cells are efforts to build a foundational model, similar to AlphaFold.

OPENAI HAS STARTED MOCKING UP WHAT ADS IN CHATGPT COULD LOOK LIKE

OpenAI employees have reportedly started discussions on different ways to prioritize sponsored information in ChatGPT. The company is considering giving priority placement to sponsored results when users are clearly talking about buying a product, showing ads based on user information, or a sponsored sidebar that shows ads relevant to the conversation. OpenAI is wary about turning off users, as they might not trust a chatbot that injects ads into sensitive conversations. The pressure to increase revenue is building on OpenAI, which signed a flurry of massive deals this year that it will have to pay for.
