StatsWire Posts Code Photo Listing Gemini 4 Hydrogen and Helix Model IDs

StatsWire posted a photo of a code diff whose flash list includes gemini-4-hydrogen-medium, -high, -tiered and bare gemini-4-hydrogen, and whose flashLite list includes gemini-4-helix variants. The poster says Google might release both models today, and the photo is the only evidence they showed.

ArgoLink, an API reseller, says Google has not announced Gemini 4 Hydrogen or any Gemini 4 Flash model. It says testers have seen Hydrogen checkpoints on Arena under the label gemini-3.8-flash, and that the only Gemini 4 model ID in Google's documentation is gemini-4-argon. It puts Gemini 3.8 Flash, Google's most intelligent Flash model, at $0.75 per million input tokens and $3.75 per million output tokens.
