**Yes, awesome-gpt-image-2 can be used with other AI models, but requires modifying the back-end API client ([`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)), updating the model registry ([`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js)), and adapting response handling to match the new provider's schema.**

The `freestylefly/awesome-gpt-image-2` repository is architected around OpenAI's GPT-Image-2.5 family (Sunburst and Flare), but its modular design allows developers to swap in alternative image generation services with targeted code changes. While the model list is currently hard-coded to OpenAI endpoints, the separation between front-end UI and back-end API forwarding makes provider substitution feasible without a complete rewrite.

## Current Architecture and OpenAI Integration

### Hard-Coded Model Dependencies

Out of the box, the application expects specific OpenAI model identifiers defined in **[`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js)**. This registry maps model names to official OpenAI documentation URLs and drives the front-end model selector:

```javascript
// src/image25/cases.js
export const models = {
  sunburst: 'https://developers.openai.com/api/docs/models/gpt-image-2.5-sunburst',
  flare:    'https://developers.openai.com/api/docs/models/gpt-image-2.5-flare',
};

```

The front-end ([`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx)) reads this object to populate the UI, while the back-end expects these identifiers when routing requests.

### API Request Flow

The request pipeline follows a strict path: the front-end sends payloads to **[`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)**, which uses the OpenAI SDK to forward requests to OpenAI's image generation endpoints. Because **[`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)** directly instantiates the OpenAI client and expects OpenAI-specific request shapes and response formats, swapping providers requires intentional modification at this layer.

## Integrating Other AI Models: Step-by-Step

To use awesome-gpt-image-2 with other AI models, modify these four specific components:

### 1. Replace the API Client in [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)

The back-end endpoint must be refactored to use the target provider's HTTP API instead of the OpenAI SDK. Replace the OpenAI SDK instantiation with an HTTP client like `axios` or `fetch`, updating the endpoint URL, authentication headers, and payload structure:

```javascript
// api/me.js - Modified for a fictional "MyAI" service
import axios from 'axios';

export async function generateImage(req, res) {
  const { prompt, model } = req.body;
  
  const response = await axios.post('https://api.myai.com/v1/images/generate', {
    prompt,
    model: model === 'sunburst' ? 'myai-sunburst' : 'myai-flare',
  }, {
    headers: { 
      Authorization: `Bearer ${process.env.MYAI_API_KEY}` 
    },
  });
  
  res.json({ image_url: response.data.url });
}

```

### 2. Update the Model Registry in [`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js)

Add entries for the new provider's model IDs so the UI can display them in the selector. The key  becomes the value sent to the back-end, while the URL can point to the provider's documentation:

```javascript
// src/image25/cases.js - Adding a custom provider
export const models = {
  sunburst: 'https://developers.openai.com/api/docs/models/gpt-image-2.5-sunburst',
  flare:    'https://developers.openai.com/api/docs/models/gpt-image-2.5-flare',
  myai:     'https://api.myai.com/docs/models/myai-sunburst',
};

```

### 3. Adapt Response Handling in Front-End Components

If the new provider returns a different JSON schema, update the parsing logic in **[`src/apimartClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/apimartClient.js)** or any component consuming the generated image URL. The front-end currently expects `image_url`, but you can implement fallback logic for alternative field names:

```javascript
// src/apimartClient.js - Handling multiple response formats
export async function fetchGeneratedImage(payload) {
  const resp = await fetch('/api/me', { 
    method: 'POST', 
    body: JSON.stringify(payload),
    headers: { 'Content-Type': 'application/json' }
  });
  const data = await resp.json();
  
  // Support both OpenAI-style and custom provider responses
  return data.image_url ?? data.imageLink ?? data.url;
}

```

### 4. Configure Environment Variables

Add the new provider's API key to **`.env.example`** and your actual environment configuration. The back-end reads credentials via `process.env`, so define a new variable (e.g., `MYAI_API_KEY`) and reference it in [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js) instead of `OPENAI_API_KEY`.

## Alternative Approach: Using a Proxy Service

If you want to avoid modifying the source code directly, deploy a **proxy service** that translates OpenAI-style requests to the target provider's format. Configure [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js) to point to your proxy URL instead of the OpenAI API. The proxy handles authentication transformation, payload mapping, and response reformatting, allowing the front-end to remain unchanged while supporting alternative models.

## Summary

- **awesome-gpt-image-2 supports other AI models**, but integration requires deliberate code changes rather than configuration toggles.
- **Modify [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)** to replace OpenAI SDK calls with the target provider's HTTP API, handling authentication and payload differences.
- **Update [`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js)** to register new model IDs for the UI selector.
- **Adapt [`src/apimartClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/apimartClient.js)** if the new provider returns image URLs in differently named fields.
- **Use environment variables** (`.env.example`) to store new provider API keys securely.

## Frequently Asked Questions

### Is awesome-gpt-image-2 restricted to OpenAI models only?

No, but it is designed for OpenAI's GPT-Image-2.5 by default. The hard-coded model registry in [`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js) and the OpenAI SDK usage in [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js) create a dependency that must be manually refactored to support other providers like Midjourney, Stability AI, or custom services.

### What is the minimum code change required to swap the AI provider?

At minimum, you must edit **[`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js)** to replace the OpenAI SDK instantiation with HTTP requests to your new provider's endpoint, and update the environment variables for authentication. If the response schema differs from `{ image_url: string }`, you must also modify the front-end consumer in [`src/apimartClient.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/apimartClient.js).

### Will the UI break if I add non-OpenAI models?

The UI will not break as long as you maintain the contract between [`src/image25/cases.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/image25/cases.js) (model registry) and [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js) (back-end handler). The front-end simply displays whatever models are listed in the registry and sends the selected key to the back-end. Ensure the back-end can handle the new model identifiers and return the expected response format.

### Can I support multiple AI providers simultaneously?

Yes, but you must implement provider-specific branching logic in [`api/me.js`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/api/me.js). For example, check the modelId from the request body and route to the appropriate SDK or HTTP client (OpenAI, MyAI, etc.) based on that value. Update the model registry to include all supported providers, and ensure each returns a consistent response format that the front-end can consume.
