Zhipu AI's open platform for GLM large models, multimodal APIs, and agent building
Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
Build tool-using agents and expose or consume MCP services to connect models to external systems.
Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
Tune models on your data and prototype prompts interactively in the browser before shipping.

Turn scans and PDFs into editable, searchable Markdown
The free tools run on WebAssembly inside your browser so receipts, medical records and financial documents never leave your machine.
The premium cloud model reads inline and block math and converts it to LaTeX syntax, which matters for research papers and textbooks.
Table borders and multi-column reading flow are preserved, and charts and illustrations are pulled out as separate image files.
Uploads and results are stored in an account so you can organise and run full-text search across your converted documents later.
Free / Open-sourceDelivers exceptional open-weight reasoning performance at very low cost, but lacks BigModel's broad enterprise multi-modal agent building suite.


Provides industry-leading frontier intelligence and developer ecosystems, but lacks BigModel's specialized GLM architecture and native Chinese language optimizations.

Offers massive context windows and robust multimodal Gemini APIs, but differs in model architecture and regional enterprise tooling.
#3SpecialistAggregates hundreds of global models under one API endpoint, whereas BigModel provides direct native infrastructure for Zhipu's GLM models.
Free online OCR that turns any image into editable text in seconds
