o1-pro Pricing
ReasoningOpenAI · 200K tokens context
o1-pro from OpenAI costs $150.00 per 1 million input tokens and $600.00 per 1 million output tokens as of June 2026 (live OpenRouter data). The model supports a 200,000-token context window (approximately 150,000 words) with a 100K-token maximum output. A typical 1,000-token request costs $0.1500 in input charges; a 10,000-token request costs $1.5000.
