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.

AI-powered SOPs and digital work instructions for the shop floor
Upload Word, Excel or PDF procedures — or photos of paper forms — and let AI produce an editable draft instruction you can verify step by step.
Each instruction is versioned and approved before release, and read acknowledgments record who confirmed which version and when.
Operators open instructions on a tablet or smartphone, scan a QR code at the machine, and get an in-app assistant that answers from your manuals.
Build checklists with photos, videos, measurement fields and sign-offs in a drag-and-drop no-code editor, with audit and inspection workflows.
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.

SpecialistOne API for 1,500+ production-ready generative media models

Free / Open-sourceSpecializes in serverless open-source model hosting and dedicated GPU clusters, but provides less native proprietary GLM model integration.

Run, fine-tune, and deploy machine learning models with one line of code
Delivers ultra-fast inference speeds for open-weight models, but focuses less on proprietary enterprise agent building toolkits than BigModel.

Free / Open-sourceOffers highly cost-effective serverless inference for open models, but lacks BigModel's integrated enterprise knowledge base and agent tools.
One API for fast, cost-predictable inference on LLMs and multimodal models
Provides strong multimodal language and audio-visual foundation models, but operates on different proprietary model architectures than Zhipu's GLM.
One cloud for 200+ model APIs, agent sandboxes and GPU compute
