A typical prompt of 500 input tokens with a 500-token answer costs $0.0050 (0.5¢) on o3. That means $1 buys about 200 prompts. Longer prompts and answers cost proportionally more.

With 500 input and 500 output tokens per request, o3 costs $5.00 per 1,000 requests. Input tokens are $2.00 per million and output tokens $8.00 per million.

o3 is more expensive than Mistral Medium 3.5 — about 1.1x more for the same request. o3 costs $2.00/$8.00 per million tokens (input/output) vs Mistral Medium 3.5's $1.50/$7.50.

o3 accepts text, images and PDFs, writes up to 100,000 tokens per response, has a knowledge cutoff of June 2024 and always reasons before answering. Its context window is 200K tokens.
