What is Portkey?
Portkey is a hosted (or self-hosted) AI gateway that routes requests across providers with fallbacks, caching, and load balancing, adds guardrails and PII checks, and logs everything for observability and cost analysis, with prompt management on top.
Key features
- Routing, fallbacks, retries, and semantic caching
- Guardrails for input and output including PII detection
- Full request logging with cost and latency analytics
- Prompt templates with versioning
- Virtual keys and budget controls
Pros
- Guardrails and observability in the same hop as routing
- Hosted option means no infrastructure
- Good enterprise controls
Cons
- Another vendor in the request path
- Pro pricing adds up alongside model spend
- Overlaps with observability tools you may already run
