Managed models mean the platform provides the models and bills you per token; BYOK (“bring your own keys”) means you connect your own provider account, your provider bills you directly, and the platform adds a small fee — a choice that comes down to cost structure, control, and how you want the data path to run.
Every enterprise AI platform eventually asks a version of this question: do you want to use our models, or plug in your own provider account? It sounds like a billing detail and it’s actually a decision about cost structure, control, and procurement — one worth making deliberately rather than defaulting into.
Here’s the trade-off, grounded in how Insulin actually offers both, so you can decide which fits your organization.
The two models
Insulin supports both paths, and you choose the model per agent:
- Managed (Suger-provided). You use Insulin’s hosted models and pay per token, at each model’s rate — shown in the console before you run. No API keys to manage, and every hosted model is available immediately.
- BYOK (bring your own keys). You connect your own provider account. Your provider bills you directly for the tokens, and Insulin adds a small, flat platform fee on top — the pricing page states it as a flat rate per million tokens, the same on every model, for input and output alike.
The mechanics matter less than what each optimizes for, which is where the decision actually lives.
When managed models win
Reach for managed models when you want the least friction and the fewest moving parts. There are no keys to provision, rotate, or secure; every model is available the moment you want to try it; and the per-token rate is visible before you commit to a run. For a team getting started, or one that values simplicity over squeezing the rate, managed is the path of least resistance and least operational overhead.
It’s also the better default when your usage is modest or spiky — you pay for exactly what you use, with nothing to reconcile against a separate provider bill.
When BYOK wins
BYOK earns its keeping when you already have a provider relationship worth preserving. The clearest case is committed-use discounts: if your organization has negotiated rates with a model provider, BYOK lets you keep them — your provider bills you at your rate, and you pay only Insulin’s flat per-million-token fee on top. At scale, that can beat paying a marked-up per-token rate.
There’s also a control argument. With BYOK the token spend runs through your own provider account, under your own agreements and controls, which some security and procurement teams prefer for governance reasons — the model usage sits inside a vendor relationship you already manage rather than a new one. If you already have the provider account, the keys, and the discount, BYOK turns them into leverage.
The decision
It comes down to three questions:
- Cost: Do you have committed-use discounts worth preserving? If yes, BYOK likely wins at volume. If no, managed’s transparent per-token rate is simpler.
- Control: Does your security or procurement team want model spend inside an existing provider relationship? That favors BYOK.
- Overhead: Do you want zero keys to manage and every model available instantly? That favors managed.
Because the choice is per agent, it isn’t all-or-nothing: you can run managed models for quick, low-volume agents and BYOK for the high-volume workloads where your negotiated rate pays off. Start managed to move fast, and move specific workloads to BYOK as the economics justify it.
Frequently asked questions
What is BYOK for enterprise AI? BYOK (“bring your own keys”) means connecting your own model-provider account to the platform. Your provider bills you directly for token usage, and the platform adds a small flat fee on top — versus managed models, where the platform provides the models and bills you per token.
Is BYOK cheaper than managed models? It can be, at volume, if you have committed-use discounts with a provider — BYOK preserves your negotiated rate and you pay only a flat per-million-token platform fee. Without a discount, managed models’ transparent per-token rate is often simpler and comparable.
Why choose managed models? For the least friction: no API keys to provision, rotate, or secure; every hosted model available immediately; and the per-token rate shown before you run. It’s the simplest path, and it fits modest or spiky usage where you just pay for what you use.
Why choose BYOK? To preserve committed-use discounts and to keep model spend inside a provider relationship your security and procurement teams already govern. If you have the account, the keys, and the negotiated rate, BYOK turns them into leverage at scale.
Do I have to pick one for everything? No. In Insulin the model choice is per agent, so you can run managed models for quick, low-volume agents and BYOK for high-volume workloads where your negotiated rate pays off. Start managed and move workloads to BYOK as the economics justify.
Takeaways
- Managed models: the platform provides them, you pay per token at a rate shown before you run. Least friction, no keys.
- BYOK: connect your own provider account, they bill you, and the platform adds a flat per-million-token fee — preserving any committed-use discounts.
- Decide on cost (do you have discounts?), control (should spend sit in an existing provider relationship?), and overhead (do you want zero keys?).
- The choice is per agent, so mix: managed for quick low-volume agents, BYOK where your negotiated rate pays off.
