$30.00/1M in · $60.00/1M out · 8K context. That's cheaper than 3% of the 298 models we track, by output price. Here's what it costs, how its price has moved, and where it fits.

cost at a typical workload
$15,000 / mo

For 1,500 input + 500 output tokens across 200,000 requests/month. That's 2500× the cheapest tracked option (Ling-2.6-flash, $6.00/mo).

Where it fits

  • Quality-first tasks where capability matters more than rate — a first-party flagship rather than a budget pick.

Watch for

  • Small 8K-token context — not for long documents or large codebases.
  • Output at $60.00/1M is among the priciest tracked — output-heavy or reasoning-heavy workloads add up fast.
  • Text-only — no image, audio, or file input.

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's pricing

Two numbers decide most of the bill: $30.00/1M for input (everything you send — prompt, context, attachments) and $60.00/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 2.0× 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.

Frequently asked questions

How much does GPT-4 cost per million tokens?

GPT-4 is priced at $30.00 per 1M input tokens and $60.00 per 1M output tokens (first-party list price) as of the 2026-06-15 snapshot. Output is the figure that usually drives the bill. Enter your own token volumes in the cost calculator for a monthly estimate.

What is GPT-4's context window?

GPT-4 has a 8K-token context window — roughly 12 pages of text. Prompt, attachments, conversation and the model's own output all share that budget, and every token you send is billed at the input rate.
