Pricing context and trust

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

Latest snapshot Jul 21, 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 Usable signal Stored history is deep enough to use trend language with more confidence. 44 stored points across 113 days. 7d, 30d, and 90d windows are already ready. No tracked window is currently blocked by missing depth. The latest stored comparison already shows a sharp move input move.
Cached pricing $0.025 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.

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.

GPT-5 Mini API pricing FAQ

Short answers for cost, monthly estimates, user-scale planning, and cheaper alternatives.

Site FAQ
How much does GPT-5 Mini cost? Current price

GPT-5 Mini currently costs $0.250 per 1M input tokens and $2.00 per 1M output tokens in the latest stored snapshot.

What is the monthly cost for GPT-5 Mini? Quick Estimate

The built-in quick estimate uses 2k input + 1k output, 20% cache hit, 300k requests / month and returns $723.00 per month. Use Calculate Cost to adjust token counts, request volume, cache ratio, batch mode, and budget.

Can GPT-5 Mini support 100 users? Workload fit

A 100-user estimate depends on how many requests each user sends and how large the prompts and responses are. This page lists context window and output limit; the calculator link is prefilled with GPT-5 Mini so you can model real traffic.

Is there a cheaper alternative to GPT-5 Mini? Similar Models

Use the Similar Models section above to open a shortlist in compare, then move to calculator once your workload assumptions are set. The page does not guess a winner from price alone because cached input, output mix, and batch mode can change the result.
