Vercel
Pros
- Zero-config deployment for Next.js with instant rollbacks
- Preview deployments for every pull request
- Vercel AI SDK provides excellent streaming and tool-calling abstractions
- Edge Functions run in 30+ regions with <50ms cold starts
- Simple and predictable pricing model
- Built-in analytics, speed insights, and web vitals monitoring
Cons
- No GPU access for running self-hosted AI models
- Function duration limits (300s Pro) can be tight for long AI inference
- Limited to web applications (no general-purpose compute)
- Vendor lock-in for Next.js-specific features (ISR, middleware)
- Can get expensive at high traffic volumes compared to self-managed
Best for
Web-based AI applications using API-based models (OpenAI, Anthropic, Gemini). Best for teams that want instant deploys, preview URLs, and the Vercel AI SDK for streaming responses.
AWS
Pros
- GPU instances (P4d, P5) for self-hosted AI model inference
- SageMaker for training and deploying custom ML models
- AWS Bedrock provides managed access to Claude, Llama, Titan models
- Full infrastructure control (VPCs, security groups, IAM)
- Lambda supports longer execution times (15 min) for complex AI tasks
- Most comprehensive cloud platform with 200+ services
Cons
- Complex pricing that is difficult to predict
- Steep learning curve with overwhelming number of services
- Deployment requires significant DevOps knowledge
- No zero-config deployment experience like Vercel
- Cold starts on Lambda can be 1-5 seconds
Best for
AI applications that need GPU access for self-hosted models, custom ML training via SageMaker, or full infrastructure control. Best when you have DevOps expertise and need services beyond web hosting.
Verdict
Choose Vercel for AI web apps that call API-based models (OpenAI, Anthropic) — you get zero-config deploys, preview URLs, and the excellent Vercel AI SDK for streaming. Choose AWS when you need GPUs for self-hosted models, SageMaker for custom ML training, or full infrastructure control. Most AI startups should start on Vercel and move specific workloads to AWS only when they need GPU compute or self-hosted inference.
Frequently Asked Questions
Can I deploy AI apps on Vercel?
Yes. Vercel is excellent for AI apps that use API-based models (OpenAI, Anthropic, Gemini). The Vercel AI SDK provides streaming, tool calling, and structured output helpers. The limitation is that Vercel has no GPU access, so you cannot run self-hosted models.
Is AWS cheaper than Vercel for AI apps?
It depends on scale and architecture. For small-to-medium web apps calling AI APIs, Vercel is often cheaper due to simpler pricing and no DevOps overhead. For GPU-intensive workloads or high-traffic apps, AWS can be more cost-effective but requires DevOps expertise to optimize.
Can I use Vercel with AWS together?
Absolutely. A common pattern is deploying your Next.js frontend on Vercel while running GPU inference, ML pipelines, or heavy backend processing on AWS. Vercel serverless functions call your AWS-hosted model endpoints. This gives you the best of both worlds.
Does Vercel support long-running AI tasks?
Vercel serverless functions have a max duration of 300 seconds on Pro plans (900s Enterprise). For longer AI tasks, use background functions, queue systems, or offload to AWS Lambda (15 min max) or EC2 for unlimited duration.
