o3 Pro Pricing

Reasoning

OpenAI · 200K tokens context

o3 Pro from OpenAI costs $20.00 per 1 million input tokens and $80.00 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 $0.0200 in input charges; a 10,000-token request costs $0.2000.
