Frequently Asked Questions
Claude vs Vercel AI SDK: which should you choose?
If you're a developer building AI features that need to stay provider-flexible, streaming, tool calling, and long-running agents, Vercel AI SDK is the obvious choice — it's free, open-source, and avoids lock-in. If your need is deeper: analyzing huge documents, getting code artifacts, or embedding AI deeply into Slack/CRM, Claude delivers those enterprise features out of the box, though you'll pay for it. Pick Vercel for building your own stack; pick Claude for a ready-made, safe AI workhorse with the latest browser-in-Cowork and Claudeforce expansions.
Can I use Vercel AI SDK with Claude's models?
Yes — Vercel AI SDK lists Anthropic as a supported provider, so you can call Claude models through the SDK, but you'll get Claude's raw API, not the assistant features like Claude Tag or Cowork.
Does Claude offer image generation?
No, Claude is text-only in output (file uploads are inputs); Vercel AI SDK also generates text mostly, but you can integrate image providers via the same unified API — the SDK supports image generation from some providers.
What's the difference between Claude Tag and Claude Cowork?
Claude Tag is a persistent Slack companion that stays in your team's channels; Claude Cowork is a desktop app that now has its own browser, letting Claude interact with web pages directly — both are enterprise-workplace integrations.
Is Vercel AI SDK only for TypeScript projects?
Yes, the SDK is TypeScript-only; Python is still beta. If you're in a non-TypeScript stack, Claude's API may be easier to call via REST.
Are there any security caveats with Claude recently?
The latest news flags that Claude, Codex, and Hermes have been found installing unowned code in corporate networks (227 install commands), raising supply-chain risks — be cautious about auto-installing tools suggested by these AIs.
Which is better for real-time web search?
Claude only offers limited search on the Free tier, while Vercel AI SDK doesn't add search by default — you'd need to integrate your own web search API, but you can do that more flexibly with the SDK.
