Zed is going straight on ChatGPT’s personal subscription this time, so there’s no need to pay per use—it's definitely more convenient. JetBrains users can keep using ACP too, but it feels like subscription-based computing power being rolled out will be the trend.

Zed announces that the built-in AI Agent is now natively integrated with ChatGPT, allowing users to directly access OpenAI models and Codex with their personal subscriptions after logging in, without the need for pay-as-you-go API fees; JetBrains and others can still use ACP. The direct enterprise key connection option remains available. Competitors are also shifting to pay-as-you-go billing, with Anthropic and Copilot implementing phased charges, as vendors are delegating subscription computing power to third-party applications to retain developers.
