Gemini 4 Argon now available on AI Gateway

Gemini 4 Argon now available on AI Gateway - Vercel

Gemini 4 Argon from Google is now available on AI Gateway .

Gemini 4 Argon is built for coding, agentic work, and complex reasoning. It has a 1M token context window, accepts text, image, PDF, and video input, and supports tool calling.

On coding tasks, Gemini 4 Argon builds features, fixes bugs, and researches unfamiliar codebases, carrying longer tasks through multiple steps. The model also reads dense diagrams, spreadsheets, layout-heavy documents, and video, which suits tasks like a financial analysis spread across several spreadsheet tabs. Beyond code, it handles work in finance, health, and law, and hard problems in math and science. Gemini 4 Argon uses thinking levels ( low , medium , and high ) instead of thinking budgets.

Call Gemini 4 Argon through the AI SDK , the Chat Completions , Responses , and Anthropic Messages APIs, or a coding agent connected to AI Gateway. Set the thinking level with reasoning in the AI SDK or reasoning_effort in Chat Completions, and see reasoning for the other controls.

Use google/gemini-4-argon as the model name:
