Supported questions move forward.
The model sees the relevant approved context, then produces an answer grounded in those sources.
Bast Platform
Build governed AI on infrastructure you control.
Deploy Bast hosted, in your private cloud, or on premises. Ground every answer in approved knowledge and keep the route back to its source.

One governed system
Four layers. One inspectable route.
The platform connects the place it runs, the knowledge it can use, the controls that shape the route, and the experience people finally see.
- 01
Infrastructure
Run where your operating constraints require: Bast hosted, private cloud, or on premises.
- 02
Data
Turn raw source material into structured knowledge the system can reason over.
- 03
Orchestration
Select relevant, approved knowledge before generation and preserve the path through the system.
- 04
Application
Deliver grounded information in the form the person needs, with its evidence still attached.
Proof before output
An answer is only one valid outcome.
When approved knowledge supports a response, Bast keeps the source route visible. When nothing supports it, the system refuses before the model guesses.
The route stays inspectable.
Source, ontology, version, and routing remain tied to the delivered response.
A clean no beats a confident guess.
If nothing supports the answer, Bast stops instead of filling the gap with fluency.
Your control
Your data. Your decisions. Your operating boundary.
- Your IP stays yours.Your knowledge never trains someone else’s model.
- Auditable.Reconstruct an answer from its source, version, and route.
- Traceable.Keep provenance with the response, from context to source page.
- Governed.Apply scope and eligibility before generation, not after.
- Deployable your way.Use Bast hosted, a private cloud, or your own premises.
