Overview

You can call supported models through a compatible API, monitor usage, and pay based on actual consumption.

Model availability, context length, and final prices may vary by model. Use the prices displayed in the console as the source of truth before starting production traffic.

Supported Model Types

AI Gateway supports multiple categories of models for common AI workloads.

Model Type	Typical Use Cases	Billing Unit
Language models	Chat, reasoning, coding, summarization, tool calling, and structured output	Input and output tokens
Long-context language models	Document analysis, large codebase analysis, and retrieval-augmented generation	Input and output tokens, sometimes tiered by context size
Claude-series models	Chat, coding, reasoning, and workflows that use prompt caching	Input tokens, output tokens, cache writes, and cache reads

Pricing

AI Gateway provides two service plans: Enterprise for production workloads and Developer for individual or experimental use. Model prices are listed in USD. Always use the unit prices displayed in the console as the source of truth.

Enterprise

Production-grade API access for enterprise workloads, with priority capacity, higher service stability, and dedicated support. Suitable for commercial applications, high-volume usage, and business-critical AI services.

Developer

Affordable API access for individual developers, testing, and non-critical workloads. Powered by shared capacity, with best-effort availability and performance that may vary depending on resource availability.

The prices below are placeholders used to illustrate each billing formula. They do not represent actual model prices.

Language Models

General language models are billed by token usage.

Usage Type	Unit Price
Input tokens	`$XX.XX` / 1M tokens
Output tokens	`$YY.YY` / 1M tokens

Billing formula:

Total cost =
  (input tokens / 1,000,000 × $XX.XX)
+ (output tokens / 1,000,000 × $YY.YY)

Tiered Context Pricing

Some language models select a pricing tier based on the total number of input tokens in a request. After the tier is selected, its input and output prices apply to the entire request.

Context Tier	Input Tokens per Request	Input Token Price	Output Token Price
Standard context	Up to the model’s tier threshold	`$XX.XX` / 1M tokens	`$YY.YY` / 1M tokens
Extended context	Above the model’s tier threshold	`$AA.AA` / 1M tokens	`$BB.BB` / 1M tokens

Standard-context formula:

Total cost =
  (input tokens / 1,000,000 × $XX.XX)
+ (output tokens / 1,000,000 × $YY.YY)

Extended-context formula:

Total cost =
  (input tokens / 1,000,000 × $AA.AA)
+ (output tokens / 1,000,000 × $BB.BB)

The exact threshold and prices vary by model and are displayed in the console.

Claude-Series Prompt Caching

Claude-series models may include prompt caching charges in addition to normal input and output token charges.

Usage Type	Unit Price
Input tokens	`$XX.XX` / 1M tokens
Output tokens	`$YY.YY` / 1M tokens
Cache write, 5-minute TTL	`$MM.MM` / 1M tokens
Cache write, 1-hour TTL	`$NN.NN` / 1M tokens
Cache read	`$ZZ.ZZ` / 1M tokens

Billing formula:

Total cost =
  (input tokens / 1,000,000 × $XX.XX)
+ (output tokens / 1,000,000 × $YY.YY)
+ (5-minute cache write tokens / 1,000,000 × $MM.MM)
+ (1-hour cache write tokens / 1,000,000 × $NN.NN)
+ (cache read tokens / 1,000,000 × $ZZ.ZZ)

Usage Notes

Check the console for the latest model list, supported parameters, context limits, and real-time prices.
For language models, estimate cost from both input and output tokens. Long prompts, retrieved documents, and tool results can increase input token usage.
For tiered-context models, the input token count determines which price pair applies to the entire request.
For cached prompts, cache writes and cache reads may appear as separate billable usage types.
Use rate limits and budget controls when integrating AI Gateway into production applications.
