Gemini 4 Hydrogen is an advanced multimodal artificial intelligence model developed by Google DeepMind for fast, efficient reasoning, software development, and autonomous AI workflows. Adapted from Gemini 4 Carbon, the model combines frontier-level intelligence with optimized performance for coding, research, and everyday productivity tasks. It supports text, images, audio, and video inputs with a unified context window of up to one million tokens. Gemini 4 Hydrogen provides four configurable thinking levels that allow users to balance processing speed with reasoning depth for different workloads. Its capabilities include iterative code generation, debugging, web development, computer use, multimodal analysis, and executing complex tasks through AI agents. Available through Google's Gemini ecosystem, the model helps developers, businesses, and individuals automate workflows, analyze information, and build intelligent applications.

GPT-6.1 Sol is an OpenAI model designed to deliver near-GPT-6 Astra intelligence at substantially lower cost across coding, professional work, computer use, scientific research, and agentic workflows. It improves on GPT-6 Sol across complex tasks such as software engineering, document analysis, multi-step business automation, and computer interaction. On DeepSWE v1.1, GPT-6.1 Sol matches GPT-6 Astra at roughly one-fifth of the cost while exceeding GPT-6 Sol's best score by 6.4 percentage points at a lower reasoning effort. The model also improves computer use, outperforming GPT-6 Sol by seven percentage points on the OSWorld 2.0 offline set at maximum reasoning effort while costing less than half as much per task. GPT-6.1 Sol provides improved factuality and alignment, including greater transparency about limitations and stronger adherence to user instructions during agentic tasks. It is available through ChatGPT Work, Codex, and the OpenAI API.
