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.
Agentic social media scheduling for 30+ channels
Write a post once and publish to every selected channel, previewing the whole schedule visually before it goes out.
Claude, ChatGPT, Claude Code, Cursor, Grok, OpenClaw and others draft, schedule and analyze posts programmatically.
Invite teammates, assign posts, and keep every channel and approval organized in a shared workspace.
Set a milestone like 100 likes and Postiz automatically posts, likes, or comments to keep engagement going.
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.

Agentic marketing platform for campaigns, creative, and social publishing
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.
