Altman Warns: GPT-5.6 Sol Demand Strains OpenAI

Sam Altman warns of potential "hiccups" for OpenAI's new GPT-5.6 Sol model. He states that the model's growth is "insane," and the inference infrastructure is struggling to keep up with demand. Here's the thing: Codex and ChatGPT Work now have 8 million active users. This is up from 5 million previously. OpenAI has already removed a five-hour rate limit and reset usage caps to manage the load. GPT-5.6 Sol launched publicly on July 9th. Its API pricing is $5 input and $30 output per million tokens. OpenAI is also using Cerebras hardware for enterprise customers, achieving speeds of up to 750 tokens per second. The bottom line: This warning signals potential performance issues or service interruptions for users relying on the OpenAI API.
