# Function: createGmicloudV3Middleware()

> **createGmicloudV3Middleware**\<`TTags`>(`options`): `LanguageModelV3Middleware`

Defined in: [gmicloud/src/ai-sdk/language-model-middleware/v3/language-model-v3-gmicloud-billing-middleware.ts:91](https://github.com/narevai/ai-billing/blob/main/packages/gmicloud/src/ai-sdk/language-model-middleware/v3/language-model-v3-gmicloud-billing-middleware.ts#L91)

Creates a V3 billing middleware for the GMI Cloud provider (`@ai-sdk/gmicloud`).
Deducts cache-read tokens from prompt tokens before billing — GMI Cloud charges only non-cached input at
the prompt rate, and cached tokens separately at the cache-read rate.

## Type Parameters

### TTags

`TTags` *extends* `JSONObject`

The shape of the tags object, extending DefaultTags.

## Parameters

### options

[`GmicloudV3MiddlewareOptions`](/docs/sdk/ai-billing/reference/gmicloud/typedoc/interfaces/GmicloudV3MiddlewareOptions)\<`TTags`>

Billing options; see [GmicloudV3MiddlewareOptions](/docs/sdk/ai-billing/reference/gmicloud/typedoc/interfaces/GmicloudV3MiddlewareOptions). A `priceResolver` is required.

## Returns

`LanguageModelV3Middleware`

A V3 billing middleware instance for GMI Cloud.

## Example

```ts theme={null}
import { createGmicloud } from '@ai-sdk/gmicloud';
import { wrapLanguageModel } from 'ai';
import { createGmicloudV3Middleware } from '@ai-billing/gmicloud';
import {
  consoleDestination,
  createObjectPriceResolver,
  type ModelPricing,
} from '@ai-billing/core';

const gmicloud = createGmicloud({ apiKey: process.env.GMI_CLOUD_APIKEY });

const customPricingMap: Record<string, ModelPricing> = {
  'deepseek-ai/DeepSeek-V4-Flash-0731': {
    promptTokens: 0.1 / 1_000_000,
    completionTokens: 0.3 / 1_000_000,
  },
};

const priceResolver = createObjectPriceResolver(customPricingMap);

const billingMiddleware = createGmicloudV3Middleware({
  destinations: [consoleDestination()],
  priceResolver,
});

const wrappedModel = wrapLanguageModel({
  model: gmicloud('deepseek-ai/DeepSeek-V4-Flash-0731'),
  middleware: billingMiddleware,
});
```
