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.

Write end-to-end test automation in plain English, no code required
Build and maintain end-to-end tests using free-flowing plain English. testRigor interprets your instructions exactly as written and executes them, with no coding required.
Tests adapt to UI changes automatically, so you spend far less time fixing broken selectors and scripts. Customers report near-zero maintenance versus Selenium and Appium.
Cover web, iOS and Android mobile, native Windows desktop, API, email, SMS, phone calls, 2FA, and mainframe testing from a single tool.
Generate tests directly in testRigor or through Claude Code using MCP and Skills, and import existing manual test cases to get started quickly.
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
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language
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.

Ship with confidence: one system of record for manual, automated, and CI tests
One API for fast, cost-predictable inference on LLMs and multimodal models
