the rag framework just made retrieval an agent's job. ragflow 0.27.2, out september 10, refactors agentic rag and stabilizes a raptor mode that keeps hierarchy from losing semantics.
retrieval stopped being a lookup.
Context
RAGFlow's v0.27.2 release notes say it was released on Sep 10, 2026. Among new features, the notes say Agentic RAG was refactored, which the notes say significantly improves reasoning speed and benchmark performance, and the 0.27 entry lists four thinking modes: Low, Medium, High and Ultra. The same page carries an older entry saying RAPTOR's AHC mode, introduced in v0.25.3, was stabilized by building individual document trees and merging them hierarchically, and an earlier entry saying GraphRAG and RAPTOR were deprecated in the UI in favour of Knowledge Compilation.
The improvement from the refactor is the vendor's claim with no numbers in that line. The RAPTOR stabilization appears under an older release entry and not under v0.27.2's list, so the note's pairing of it with 0.27.2 is partly misattributed, and the page mixes existing and new features. The release line gives no mechanism detail, so retrieval an agent's job and retrieval stopped being a lookup are the author's framing.
Watch next
- Benchmark numbers for the refactor.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
