GPT-6.1 Sol Pro is the same underlying model as [GPT-6.1 Sol](https://openrouter.ai/openai/gpt-6.1-sol), served with `reasoning.mode` set to `pro` for higher-quality responses on complex tasks. **Cost note:** pro mode spends far more...
About OpenAI: GPT-6.1 Sol Pro
OpenAI: GPT-6.1 Sol Pro is a language model developed by OpenAI. It's particularly well-suited for analyzing images, screenshots, and visual content, tackling complex, multi-step reasoning problems, orchestrating tool-using agents that call APIs and external services, grounding responses in real-time web search results, producing structured outputs for reliable data extraction, and handling large contexts of up to 1.1M tokens. Its 1.1M-token context window means you can pass in entire documents, codebases, or conversation histories without losing context.
As of Oct 1, 2026, OpenAI: GPT-6.1 Sol Pro costs $0.300 per 1M input tokens and $1.50 per 1M output tokens on Qubax, versus $1.00 / $5.00 on OpenRouter (70% less on input). A typical 1,000 chat requests (2K tokens in, 500 out) come to about $1.35. 2 independent compute providers currently serve it, so requests fail over automatically. Pay with USDC, USDT, BTC, ETH or 200+ other coins — no credit card required.
