OpenRouter announced that the GPT‑6.1 Sol Pro model is now available through its API. The model is the same as GPT‑6.1 Sol but runs with `reasoning.mode` set to `pro`, which aims for higher‑quality answers on difficult prompts. It is offered in batch mode, meaning users can submit many requests at once. The pro mode uses more compute, so the cost per token is higher. The model can handle up to 1,050,000 tokens of context.

## The facts

- Model: GPT‑6.1 Sol Pro (batch)
- Context window: 1,050,000 tokens

## Why it matters

The larger context window and higher‑quality reasoning let developers tackle more complex, data‑heavy tasks with fewer API calls.
