Key Takeaways
- 1Tying your codebase to a single AI provider is a massive technical debt trap.
- 2Use an abstraction layer like the Vercel AI SDK to unify your AI calls.
- 3Swapping from OpenAI to Anthropic should take exactly one line of code.
- 4Centralize your model calls using an AI Gateway to manage rate limits and routing.
- 5Write your generation logic once and decouple it from the underlying LLM.
Stop marrying your codebase to OpenAI. OpenAI drops a new model on a Tuesday. Anthropic counters with Claude 3.5 Sonnet on Thursday. Google forces a new Gemini into the mix by Friday.
If you rewrite your API calls every time the leaderboard changes, you are burning cash and dev cycles. Hardcoding provider SDKs is a technical debt trap.
The only architecture that survives the model wars
At Kyto, we refuse to hardcode vendor SDKs. We use the Vercel AI SDK to build a standardized wrapper over every major provider.
You write your prompt, your tools, and your streaming logic exactly once. Swapping from GPT-4o to Claude takes seconds, not a two-week sprint.
- Unified APIWrite a single `generateText` function and use it everywhere in your app.
- Provider agnosticSwitch between `@ai-sdk/openai` and `@ai-sdk/anthropic` without refactoring your core logic.
- Streaming out-of-the-boxSend text to the frontend chunk by chunk. Stop fighting with manual Server-Sent Events.
Your code should not care who generates the text. It should only care that it is fast, cheap, and accurate.
Stop talking, show the code
Let's build a simple generation script. Install the core library and your specific providers. If you need OpenAI and Anthropic, just run `npm install ai @ai-sdk/openai @ai-sdk/anthropic`.
- Import the core functionGrab `generateText` from the `ai` package.
- Select your providerImport `anthropic` from `@ai-sdk/anthropic`.
- Execute the callCall `generateText({ model: anthropic('claude-3-5-sonnet-latest'), prompt: 'Fix my life' })`.
- Swap providers laterChange that model string to `openai('gpt-4o')`. No structural changes. No rewritten types.
Use an AI Gateway
Want to avoid provider SDKs altogether? Use Cloudflare or Vercel's AI Gateway. Import `gateway` from the `ai` package and pass `gateway('anthropic/claude-3-5-sonnet')`. One single endpoint to rule them all.
Stop building AI features that break next month.
Kyto builds provider-agnostic AI infrastructure for companies that want reliable systems, not technical debt.
Book a technical callFrequently Asked Questions
Why shouldn't I just use the official OpenAI SDK?
Because OpenAI won't always win. When Anthropic or Google drops a faster, cheaper model, a unified API lets you switch providers in seconds, not sprints.
What is the Vercel AI SDK?
An open-source TypeScript library that gives you a single, unified interface to interact with OpenAI, Anthropic, Google, and local models.
