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.
ChartPixel turns messy spreadsheets, surveys and webpage tables into interactive charts, written insights, forecasts and statistical tests. Upload a file, and the platform cleans and enhances the data, picks the most useful chart types, explains what each one shows, and lets you chat with your data.
Upload Excel or CSV files, or read tables from a webpage, and the platform tidies the data and picks the most insightful chart types for you.
Each chart comes with a written description, key takeaways and the supporting statistics, so findings are presentable immediately.
Ask questions of your dataset and its charts in natural language to dig into correlations and outliers without writing queries.
Run trend forecasts, statistical tests, sentiment analysis on comment fields and maps generated from postcode data.
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
SpecialistChat with your data to get analysis, charts, reports, and slides
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.
