GPT-6.1 Sol Pro

openai/gpt-6.1-sol-pro

GPT-6.1 Sol Pro is the same GPT-6.1 Sol model, OpenAI's near-Astra GPT-6 tier, served in OpenAI's pro reasoning mode rather than as different weights. Pro mode spends more model work on each request before returning a single final answer, which OpenAI says can improve reliability on difficult tasks such as complex optimization, high-value code review and deep analysis. It increases latency and token usage, so standard GPT-6.1 Sol remains the default for routine work.
