# Resolving AI Image Generation Timeout on Vercel

## Problem Description

When using AI image generation models (such as `gpt-image-1`) on Vercel, you may encounter timeout errors. This occurs because AI image generation typically requires more than 1 minute to complete, which exceeds Vercel's default function execution time limit.

Common error symptoms include:

- Function timeout errors during image generation
- Failed image generation requests after approximately 60 seconds
- "Function execution timed out" messages

### Typical Log Symptoms

In your Vercel function logs, you may see entries like this:

```plaintext
JUL 16 18:39:09.51 POST 504 /trpc/async/image.createImage
Provider runtime map found for provider: openai
```

The key indicators are:

- **Status Code**: `504` (Gateway Timeout)
- **Endpoint**: `/trpc/async/image.createImage` or similar image generation endpoints
- **Timing**: Usually occurs around 60 seconds after the request starts

## Solution: Enable Fluid Compute

For projects created before Vercel's dashboard update, you can resolve this issue by enabling Fluid Compute, which extends the maximum execution duration to 300 seconds.

### Steps to Enable Fluid Compute (Legacy Vercel Dashboard)

1. Go to your project dashboard on Vercel
2. Navigate to the **Settings** tab
3. Find the **Functions** section
4. Enable **Fluid Compute** as shown in the screenshot below:

5. After enabling, the maximum execution duration will be extended to 300 seconds by default

### Important Notes

- **For new projects**: Newer Vercel projects have Fluid Compute enabled by default, so this issue primarily affects legacy projects
