About

Gemini 4 Argon is Google's frontier AI model designed for complex, long-horizon workflows across software engineering, enterprise knowledge work, cybersecurity defense, and creative writing. The model supports coding, reasoning, multimodal understanding, and multi-step agentic tasks, with an expanded output limit of up to 1 million tokens for particularly long or complex trajectories. Google reports that Argon scores 77.9% on DeepSWE v1.1 for long-horizon software engineering and 51.3% on AutomationBench for end-to-end business automation. Its enterprise capabilities extend to areas such as financial research, legal research and drafting, professional chart analysis, long-video understanding, and workflows involving multiple documents. Argon is also designed for defensive cybersecurity and can autonomously identify, validate, and patch software vulnerabilities, tying for first with a 68% score on CWE-bench v1 in Google's reported results.

About

Hy4 preview is a new-generation open source Mixture-of-Experts flagship model built for real-world productivity tasks across software engineering, office work, game development, and scientific research. The model contains 770B total parameters with 49B activated per token and supports a 1M-token context window, giving it the capacity to work through large codebases, extensive document collections, and long multi-step tasks. Its 78-layer architecture combines Gated DeepSeek Sparse Attention with IndexCache for cross-layer sparse index reuse and identity Hyper-Connections to expand information flow between layers. A native Multi-Token Prediction layer is included for speculative decoding. Hy4 preview is designed to understand, plan, debug, and verify long-horizon engineering tasks, with additional gains in front-end visual quality and interaction design.
