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.
Real-time guest photo sharing and digital RSVP invitations for unforgettable events
Guests scan a QR code and their photos and videos appear on any TV, projector or tablet within seconds, tagged with their name and message.
Choose from 90+ invitation designs, collect replies, guest details and preferences, and keep everyone updated through one link.
The upload page opens in the phone's browser, so nobody has to download anything or sign up to contribute.
Approve photos before they display or let them flow and remove unsuitable ones later, backed by AI moderation for larger events.
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
AI content filtering and parental control that doesn't block the internet

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.

Detect AI-generated text and images with benchmark-tested accuracy

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
