Microsoft unveiled Rayfin and Web IQ to make Fabric a governed AI backend runtime and to ground agents on live web data with lower token costs.
With Rayfin, Microsoft is pitching a code-first backend for Microsoft Fabric: define databases, APIs, business logic, identity, and access policies in code, then deploy to a managed runtime that inherits governance from day one.
Web IQ gives agents real-time web grounding (pages, news, images, video) optimized to reduce token use and latency. It already underpins Copilot and ChatGPT grounding and aims to replace brittle DIY stacks for multi-step retrieval.
Upstream, teams are reworking specs and context for agents moving at machine speed; Allstacks’ new workspace is a sign of that shift DevOps.com.
Fabric with Rayfin centralizes backend, data, and governance so agent apps don’t sprawl across ad hoc runtimes.
Web IQ cuts token and latency overhead in web grounding, which dominates multi-step agent costs.
-
terminal
Build a small agent using Web IQ vs your current RAG/search stack; compare tokens, latency, and answer quality on 5–10 step tasks.
-
terminal
Prototype a CRUD + policy service with Rayfin on Fabric; verify inherited identity, access, audit, and data locality behaviors.
Legacy codebase integration strategies...
- 01.
Map current identity, data domains, and policy-as-code to Fabric equivalents; check parity and gaps before migrating workloads.
- 02.
Run a TCO model: Fabric + Web IQ vs your stitched stack (egress, token spend, orchestration maintenance).
Fresh architecture paradigms...
- 01.
Default to Fabric + Rayfin for new agent backends to avoid platform sprawl and get governance on day one.
- 02.
Design agents spec-first with a shared context workspace to reduce rework as autonomy increases.
