OPENAI ISN'T YET WORKING TOWARD AN IPO, CFO SAYS

OpenAI's Chief Financial Officer, Sarah Friar, said the company is not planning to IPO in the short term. It will instead prioritize growth and R&D over profitability. OpenAI is hoping the government will support its offers to increase data center capacity by helping to guarantee the financing for the chips behind its deals. The depreciation rates of AI chips are uncertain, making it more expensive for companies to raise the debt needed to buy them. Friar claims OpenAI could reach profitability on very healthy gross margins if it weren't seeking to invest so aggressively.

Perplexity published code enabling trillion-parameter mixture-of-experts models to run efficiently across multiple AWS servers for the first time, opening up less advanced data centers to AI inference. The challenge is that large models, even many open weights models, are too large to fit on single servers, but AWS' networking hardware was too slow for the constant inter-server communication these models require.
