OpenAI said Thursday it will pause new subscriptions to its $200-a-month plan for Astra, its new flagship model, another sign of the compute crunch facing AI companies.

OpenAI has told some business partners that it will no longer accept advertising in ChatGPT for image- and audio-generating products—which compete with its own features.

The change, which hasn’t been previously reported or reflected in its published ads policy, blindsided existing advertisers such as Adobe, which sells such products. And if extended to other competing products, the new policy could narrow OpenAI’s potential ad revenue. OpenAI has given investors aggressive projections for ad growth, which it sees as a key way to make money off its large audience of people who don’t pay for the service.

Even before Stripe entered talks to buy startup OpenRouter for $10 billion, several tech companies were exploring or developing router technology, which helps customers use the most cost-effective AI models.

That’s been the experience of Thibault Jaigu, CEO and co-founder of Requesty, a five-person UK startup whose software routes developers using AI to various models. “The race to optimize is crazy,” said Jaigu, who said at least 25 companies had approached Requesty in the past couple weeks wanting to talk, including about possible investments, acquisition or other partnerships. 

By optimize, Jaigu is referring to developers’ demand for tech that helps cut costs by switching to older models from Anthropic, Google and OpenAI for some tasks, or to cheaper open-source alternatives such as China’s Kimi. Need for this technology has risen as AI agents consume more tokens, the units of text or other data that are the basis for pricing many AI services, and as open-source technology has advanced.
