Gemini 4 Carbon, a checkpoint first reported inside Google's Jetski coding tool, is now being tested by partners in an early access program.
According to X user Lentils, a Carbon early access program has started, with partners getting access and the model being tested on LM Arena, and they expect a release 'very close'.
Reliable leaker Lyra quoted a post with a screenshot of Google's Gemini API Early Access Program docs, which describe an invite-only group of developers, researchers and partners getting upcoming Gemini API and AI Studio models before launch.
