Google releases Gemini 4 Argon frontier reasoning model with 1M context
What happened.Google DeepMind released Gemini 4 Argon, a natively multimodal reasoning model designed for long-horizon autonomous workflows with a unified 1-million-token context window.
Why it matters.Long-horizon agentic workflows require deep reasoning without context exhaustion. A unified 1M input-output window allows builders to execute complex autonomous refactoring loops over massive codebases.
