Grok 4.7 is xAI's (listed on OpenRouter under the SpaceXAI brand) proprietary flagship model, succeeding Grok 4.6, with a 500K-token context window and up to 450K output tokens. It is positioned for long-running software-engineering agents and knowledge work, with particular emphasis on verifying its own work over extended, multi-step tasks.
GPT-6.1 Sol is OpenAI's upgrade to GPT-6 Sol (1.05M-token context, $2/$10 per million input/output tokens), released September 29, 2026 at DevDay below the flagship GPT-6 Astra. OpenAI says it nearly matches Astra on agentic coding, computer use, and professional work at a fifth of the price, making it a strong default for coding agents and document-heavy workflows.
