Google is moving to add "xhigh" to the setting that controls reasoning depth (thinking level) in its developer-facing Gemini API, according to changes in its official SDKs (software development kits). The values are ordered minimal, low, medium, high and xhigh, and xhigh appears to be a level above "high," the deepest so far. The addition also appeared in release notes for the official Python, JavaScript and Java SDKs dated Nov. 10. Google has not announced it on its official blog or official X accounts, so the information remains an unannounced leak. Supported models, pricing and whether the value can actually be called have not been disclosed.
