The best open source models for KYC and KYB checks
For KYC and KYB checks, our top pick is Qwen3.8 27B from Qwen (Alibaba). A compact vision-language model under Apache 2.0, easy to host next to your KYC data. GLM-5.3 Flash is a close second, and DeepSeek V4.1 Flash rounds out the list.
KYC and KYB agents check identity documents, business filings, and beneficial owners, then flag mismatches for review. The inputs are images and PII, so vision and the ability to self-host matter most.
