The author shares the full Gemini 4 model guide link. As shown in the guide screenshot, Hydrogen, Argon, and Carbon share a 1M unified context window: Carbon is the strongest frontier model for hard reasoning, Argon covers most long-horizon tasks with fewer tokens, Hydrogen is the fast $1.50/$7.50-per-1M upgrade from Gemini 3.8 Flash, and Google recommends pairing Carbon (planning, hard roadblocks) with Hydrogen (code edits, parallel subagents) in one workflow.
