🚨 Gemini 4 Hydrogen has returned 200 on Google Vertex API
We called gemini-4-hydrogen on Vertex AI's global endpoint. It answered "I am Gemini 4 Hydrogen, a large language model built by Google." and the response's model version field says gemini-4-hydrogen.
It isn't in Google's Vertex model catalog yet, and Google hasn't announced it.
Gemini 4 hydrogen, bhbench
depending on pricing this could be one of the best results for a cheap model yet!

Google is adding a Decisions API to the Gemini API ⚖️
New PRs in all four official Gemini SDKs (Python, JS, Go, Java) add client.decisions.create, similar to OpenAI's Decisions API. It asks a batch of questions about one shared input and returns calibrated probabilities instead of text:
• yes/no: P(true) plus a confidence score
• pick one of 2 to 255 options
• rubric score over 2 to 255 levels
Not announced yet. Spotted in googleapis/python-genai PR #3353.
