Google just released Gemini 4 Argon which is its most capable model designed specifically for complex reasoning, advanced coding, math, and science.

To help you get building right away, we just published the Gemini 4 Argon API Crash Course on the freeCodeCamp.org YouTube channel. In just 10 minutes, you’ll walk through writing clean JavaScript to connect to the model, steer its reasoning, and build real applications.

Here are the key concepts you will learn:

Configurable Thinking Levels

Learn how to tune the model’s internal reasoning between low, medium, and high so you only pay for the computational depth your specific task requires.

Multi-Turn State with previous_interaction_id

Maintain context across back-and-forth prompts without manually passing full chat histories back into every API request.

Asynchronous Background Execution

Offload heavy workloads directly to Google’s infrastructure without encountering client timeouts.
