For 1,500 input + 500 output tokens across 200,000 requests/month. That's 233× the cheapest tracked option (Ling-2.6-flash, $6.00/mo).

Where it fits
- Long inputs — a 1.0M-token window holds roughly 1,571 pages of text at once.
- Multimodal prompts — accepts image input alongside text.
- Quality-first tasks where capability matters more than rate — a first-party flagship rather than a budget pick.
Watch for
These notes are derived from price, context and modality — structural facts, not measured quality. Measured cost-to-finish-a-task lives on the real-cost index.

How to read GPT-4.1's pricing
Two numbers decide most of the bill: $2.00/1M for input (everything you send — prompt, context, attachments) and $8.00/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 4.0× the input rate here, so the shape of your workload — how much it reads versus writes — matters as much as the headline figure. This is the provider's first-party list price, reconciled against the routed market each run.

What is GPT-4.1's context window?
