Bring Your Own Model: 638Labs Unopinionated Approach
Right now, in 2025, the world of AI isn’t a seamless general intelligence — it’s a loose federation of narrow, useful agents: summarizers, recommenders, translators, code fixers, search enhancers. And most of these services live behind APIs, not platforms. Especially for small and fast-moving teams, AI isn’t a monolith — it’s a patchwork of deployed endpoints.
That’s where 638Labs fits in.
What 638Labs Is
638Labs is a lightweight, developer-first infrastructure layer for deployed AI services. At its core, it offers:
- A registry of invokable, online-only endpoints
- A forward proxy that routes OpenAI-compatible requests securely
- A clean separation between what you’ve deployed and how you expose it to others or your own stack
We don’t host your models. We don’t wrap your functions. We don’t enforce contracts. If it’s accessible over HTTP, we can route it.
What 638Labs Is not
We’re not a model host, fine-tuning provider, or training platform.
We don’t require you to upload files, checkpoint models, or containerize workloads.
We’re not an agent runtime like CrewAI or LangGraph — but we can route to them.
Why This Matters — Especially for Agile Teams
Teams building fast need flexibility, visibility, and control. With 638Labs:
- You can test, trace, and switch between models quickly
- You avoid vendor lock-in or the burden of full-stack platforms
- You get centralized logging, routing, and basic controls without ceremony
- You can bring your own models — OpenAI, Hugging Face, self-hosted, or anything else
You stay in control. We just forward the calls.
Use Cases
Use 638Labs when:
- You’re prototyping new agents but don’t want to rebuild infra each time
- You want to expose internal AI services to different clients without rewriting
- You’re mixing commercial APIs and your own endpoints
- You want a future path to exposing some agents publicly — without rebuilding
- You want a stable API surface for your business or enterprise tools, while freely changing the underlying models behind the scenes
- You want to version your AI services (dev, test, prod) and roll forward or backward as needed
Final Word
The AI world might move toward consolidation. But right now, it’s fragmented — and that’s not a bug. It’s a sign of progress, experimentation, and choice.
638Labs exists to help you route, trace, and manage that world — without getting in your way.
Bring your own model. We’ll take it from there.
