OpenAI has released GPT-6.1 Sol on the OpenRouter platform. The model sits between the entry‑level GPT-6 Sol and the top‑tier GPT-6 Astra in the GPT‑6 series. It is marketed for agentic coding, computer use, and handling document‑heavy professional tasks. The API supports a context window of 1,050,000 tokens, allowing much longer inputs than earlier models.
Why it matters
The larger context window lets developers work with far longer texts in a single prompt, improving productivity for coding and document‑intensive applications.
