import { fal } from '@fal-serverless/edge'
export default async function handler(req: Request) {
const { prompt } = await req.json()
const result = await fal.run('fal-ai/flux-pro', {
input: {
prompt,
image_size: '1024x1024'
}
})
return new Response(JSON.stringify(result), {
status: 200,

// 預熱模型
await model.generate('warmup')
return new Response('Model warmed up', { status: 200 })
}
技巧 2:請求批處理
// api/batch.ts
export default async function handler(req: Request) {

}
6.2 錯誤處理與回退
策略:
- 超時處理:設置 10 秒超時,自動重試
- 降級模式:主模型失敗時,使用較小的模型
- 回退 API:OpenAI API 失敗時,使用本地模型
export default async function handler(req: Request) {
try {
const result = await model.generate(req.body)
return new Response(JSON.stringify(result))
} catch (error) {
// 降級到較小模型
const fallback = await fallbackModel.generate(req.body)

Preface: When AI applications enter the era of edge computing
In 2026, AI application deployment will undergo a fundamental shift. The traditional cloud computing model is being replaced by edge computing and serverless architecture, and Vercel Functions is the core driver of this transformation.
Core Insight: When AI model inference is combined with serverless edge computing, what you get is a true “edge AI application” with sub-120ms response time and automatic expansion capabilities.
1. AI advantages of Vercel Functions
1.1 AI-optimized architectural features
Vercel Functions provides unique architectural advantages for AI applications:
- Automatic expansion: Automatically adjust according to request volume, no need to reserve resources
- Global CDN Deployment: 4+ regions with automatic routing to reduce latency
- I/O bound optimization: specially designed for I/O bound tasks such as AI inference
- Fluid Compute: Optimized concurrency processing, reducing cold starts
1.2 Performance characteristics of AI applications
Key Indicators:
- Response time: Usually in the range of 120-300ms (including model inference)
- Concurrency: A single instance can handle 10-50 requests/second (depending on model size)
- Cost Model: Pay as you go, no fixed costs
- Expansion Boundary: automatic expansion, no upper limit
2. AI model deployment mode
2.1 Select deployment mode
Depending on the model type and needs, choose the appropriate deployment mode:
| Model Type | Recommended Deployment | Reason |
|---|---|---|
| Small inference model (<1B parameters) | Vercel Functions (local) | Low latency, no external dependencies |
| Medium Model (1-7B Parameters) | Vercel Functions + External Inference | Balancing Latency vs. Cost |
| Large models (>7B parameters) | External inference APIs (such as OpenAI) | Reduce latency and avoid cold starts |
2.2 Production-level deployment mode
Recommended Architecture:
用戶請求
→ Vercel Functions(邊緣節點)
→ 模型推理(本地或外部)
→ 響應返回(<300ms)
Implementation example:
// api/generate-image.ts
import { fal } from '@fal-serverless/edge'
export default async function handler(req: Request) {
const { prompt } = await req.json()
const result = await fal.run('fal-ai/flux-pro', {
input: {
prompt,
image_size: '1024x1024'
}
})
return new Response(JSON.stringify(result), {
status: 200,
headers: { 'Content-Type': 'application/json' }
})
}
3. Cost Analysis: Economic Model of Production-Level AI Applications
3.1 Cost structure decomposition
Vercel Functions Cost:
- Calculation: $0.0001/GB-second (approximately $0.0001/second)
- Data Transfer: Pay per usage
- CDN Traffic: Free for the first 100GB/month, then $0.89/GB
Model inference cost:
- Local Inference: GPU cost (~$0.0005/sec)
- External API: OpenAI GPT-5.4 approximately $0.001/1K tokens
3.2 ROI calculation framework
Scenario: Customer Support Automation Agent
Investment:
- Development time: 2 weeks (1 developer)
- Operating costs: $500/month (Vercel + API)
Output:
- Process 100 requests per hour

ROI: 4,000% (payback within 4 weeks)
4. Implementation Guide: From Zero to Production
4.1 Development process
Step 1: Preparation
# 安裝 Vercel CLI
npm install -g vercel
# 登錄
vercel login
Step 2: Create AI Function
// api/chat.ts
import OpenAI from 'openai'
const client = new OpenAI({
apiKey: process.env.OPENAI_API_KEY
})
export default async function handler(req: Request) {
const { messages } = await req.json()
const completion = await client.chat.completions.create({
model: 'gpt-5.4',
messages,
temperature: 0.7
})
return new Response(JSON.stringify(completion), {
status: 200,
headers: { 'Content-Type': 'application/json' }
})
}

// vercel.json
{
"functions": {
"api/*.ts": {
"runtime": "nodejs18.x",
"memory": 1024,
"maxDuration": 10
}
}
}
4.2 Monitoring and Observability
Key Indicators:
- Delay P95: < 300ms
- Error rate: < 1%
- Request Throughput: > 100 req/s
- Cost Efficiency: >$0.001/request
5. Comparison with other platforms
5.1 Vercel vs Cloudflare Workers
| Metrics | Vercel Functions | Cloudflare Workers |
|---|---|---|
| Delay | 120-300ms | 100-250ms |
| Model Support | Local Inference + External API | Local Inference + External API |
| CDN Coverage | 4+ Regions | 300+ Regions Worldwide |
| Cost | By Usage | By Usage |
| Applicable scenarios | AI application optimization | Edge computing optimization |
5.2 Select recommendations
Select Vercel Functions when:
- Prioritize latency and user experience
- Model size < 7B parameters
- Requires global CDN optimization
Select Cloudflare Workers when:
- Prioritize global coverage
- Need for wider regional support
- Combination of model reasoning and edge computing
6. Production-level best practices
6.1 Performance optimization techniques
Tip 1: Warm up the model
// api/prefetch.ts
export default async function handler(req: Request) {
// 預熱模型
await model.generate('warmup')
return new Response('Model warmed up', { status: 200 })
}
Tip 2: Request batching
// api/batch.ts
export default async function handler(req: Request) {
const { prompts } = await req.json()
// 批處理請求,減少 API 調用次數
const results = await Promise.all(
prompts.map(p => model.generate(p))
)
return new Response(JSON.stringify(results))
}
6.2 Error handling and rollback
Strategy:
- Timeout handling: Set a 10-second timeout and automatically retry
- Downgrade Mode: Use a smaller model when the main model fails
- Fallback API: When OpenAI API fails, use local model
export default async function handler(req: Request) {
try {
const result = await model.generate(req.body)
return new Response(JSON.stringify(result))
} catch (error) {
// 降級到較小模型
const fallback = await fallbackModel.generate(req.body)
return new Response(JSON.stringify(fallback))
}
}
