AI API price calendar

What your AI API bill does over the next few months from changes providers have already announced: 91 model shutdowns and 7 scheduled price changes between September 1, 2026 and March 31, 2027, across OpenAI, the Gemini API, Azure and Amazon Bedrock. Checked September 29, 2026. List prices; runs in your browser; we don't receive your numbers.

Your workload, month by month

Add the models you use with your monthly tokens. After a shutdown, a model is billed at the provider's named replacement; scheduled price changes apply from their date. Worked example: 2 announced changes take it from $987 to $1,780 a month.

Example workload — replace with yours.

ModelInput tokens / mo (M)Output tokens / mo (M)% cached inputAfter Oct 23, 2026

Up to 8 models. Find your monthly token counts on the OpenAI usage dashboard or Claude Console usage.

Output tokens after a migration: 0%Newer models can produce more or fewer tokens for the same task. We assume the same count unless you change this.Monthly cloud bill (AWS/Azure/GCP), optional

From announced changes alone, this workload goes from $987/mo in Oct 2026 to $1,780/mo in Mar 2027 (+80.4%).

Methodology and limits

Sources. Prices are list prices in USD per 1M tokens from each provider's pricing page. Dates and named replacements come from each provider's deprecation or retirement page. Every row shows its source, a short quote from that page, and the date we last checked it. A weekly job re-reads every source page and flags any row whose quote no longer matches, for a person to review.
Replacements. The replacement shown is the one the provider names, not our recommendation. Quality and behavior can differ. The calculator's optional "your pick" is yours, and is labeled that way.
Token counts. We assume the same token counts after a migration unless you move the output-token slider — tokenizers and reasoning tokens differ between models.
The math. Monthly cost per model =input × (1 − cached share) × input rate + input × cached share × cached rate + output × output rate, with rates per 1M tokens. When a provider publishes no cached-input price, the input rate is used for cached tokens. A change that lands mid-month is prorated by calendar days: an event on day d of a month with Ddays bills old × (d − 1) ÷ D + new × (D − d + 1) ÷ D that month. Percent changes on event pages use a blended price of (3 × input + 1 × output) ÷ 4.
Not included. Discounts, committed-use or enterprise agreements, batch pricing, regional or data-zone pricing, and prices for Azure OpenAI and Amazon Bedrock (their dates are listed). Image, audio, realtime, embedding and fine-tuned models are listed but not priced.
Soft dates. Dates marked "at least through" (a promotion) or "not before" (Google lists earliest possible shutdown dates) are shown but never applied in the forecast.
Aliases. If you call an alias (for example o4-mini) rather than a dated snapshot, check which snapshot it points to.
Privacy. Calculations run in your browser. We don't receive your numbers. Analytics counts page views and button clicks only.
Other trackers. Shutdown dates are also listed byTokenGauge, benchr and llmlatency.dev. This page adds scheduled price changes, the cloud-billed routes, and your workload's total.

FAQ

What does the AI API price calendar show?

Every announced AI API model shutdown and scheduled price change from September 1, 2026 to March 31, 2027: OpenAI, Google's Gemini API, and the Azure (Microsoft Foundry) and Amazon Bedrock routes. Each row has the provider's named replacement, the price before and after where both are published, the official source, a short quote from it, and the date we last checked.

Why does the same model retire on different dates?

Because the date depends on which bill the model is on. OpenAI, Azure and Amazon Bedrock each publish their own schedule. For example, o3-mini shuts down on the OpenAI API on October 23, 2026 but on Azure on November 19, 2026, and the named replacement differs too.

Is the replacement shown the cheapest option?

No. It is the replacement the provider names, not our recommendation. Quality and behavior can differ, and a cheaper model may suit you better. The calculator lets you set your own pick, labeled as yours.

How is the monthly cost forecast calculated?

Each model costs input × (1 − cached share) × input rate + input × cached share × cached rate + output × output rate, using list prices per 1M tokens. After a shutdown the model is billed at the named replacement's price; a change that lands mid-month is prorated by calendar days. Discounts, batch and regional pricing are not included.

Do you see the numbers I enter?

No. The calculator runs in your browser and we don't receive your numbers. A shared result link contains the numbers you entered, so only share it where you're comfortable. Analytics counts page views and button clicks only.

How current is the data?

Rows were last checked on September 29, 2026, and every row shows its own check date. A weekly job re-reads each official source page and flags any row whose quote no longer matches, for review.

List prices, USD, directional. AI API price calendar rows are transcribed from each provider's official pages and checked on the date shown; confirm with the provider before relying on a number.Checked 2026-09-29.
