GPT-5 Nano

Official-first sourcing stays preferred. Verified fallback only appears when official pages block crawlers, and the history signal badge shows whether this trend view is still warming up or already usable.

Display currency

Current prices, reference costs, recent deltas, and history values switch to the selected display currency when FX is available.

Using USD display for price cards and history values.

At a glance

This block answers the immediate questions: where the price came from, how fresh it is, whether history is still warming up, and whether cache or batch pricing is explicitly listed.

Latest snapshot Apr 13, 22:05 Most recent stored public pricing point for this model.
Source PricePerToken OpenAI Source page Keep the source link visible so the latest stored number stays manually verifiable.
Source mode Fallback source Verified fallback is in use because the preferred official page is not consistently crawlable right now.
History signal Warming up Tracking is still warming up. 2 stored points across 14 days. 30d and 90d windows are still awaiting depth.
Cached pricing $0.0050 Cached input pricing only appears when the source exposes it clearly.
Batch discount Not listed Shown only when a provider-listed batch price is normalized. Do not mix it with realtime pricing assumptions.

Change intelligence

This strip answers the practical questions: has this model moved, how meaningful was the move, is history deep enough, and which page should you open next.

Open compare Run in calculator
Latest move No recent delta No recent delta has been detected between the latest two stored snapshots.
Stored history 2 points · 14 days First comparison. You can compare the latest move, but longer windows are still thin and may overstate short-term noise.
Strongest window 7d change looks flat This window looks stable. Use the current price card and broader history depth to decide.
Recommended next step Open compare There is enough recent context to compare this model against alternatives rather than looking at a single price card.

How to read this estimate The reference workload is a fast sanity check, not a forecast. If your prompt shape, cache ratio, or monthly traffic differs, jump to the calculator with this model preselected and adjust the assumptions there.

Latest detected changes

Compared against the previous recorded snapshot for this model.

Apr 13, 22:05

You can compare the latest move, but longer windows are still thin and may overstate short-term noise.

No delta yet Waiting for another snapshot A price change needs at least two recorded points. This model currently has too little history to show a delta or nothing has changed yet.

Trust policy This page stays official-first whenever the provider page is crawlable. If not, verified fallback or baseline states stay explicit so the source trace never over-claims a live official crawl.
Source note Fallback snapshot from PricePerToken because OpenAI official pricing pages currently return an anti-bot challenge to server-side crawlers. Source updated at 2026-04-12T09:23:55.468156Z.

When this model detail is enough

Use this page when you need a single-model read: current price, source traceability, recent change strength, and enough stored history to judge whether the latest move is actionable.

When to escalate to compare

If a recent price cut or a stable multi-point window makes this model newly competitive, move to compare so every candidate runs against the same workload assumptions.

When to escalate to calculator

If a recent price increase changes spend assumptions or history is still thin, use calculator next so you can replace the reference workload with your own traffic, cache ratio, and budget ceiling.
