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.
Free AI captions for every image you post
Upload a photo and let the AI read its content and produce caption text that fits the picture rather than generic filler.
Generate captions in over twenty languages, including English, Spanish, Portuguese, German, French, Chinese, Japanese, Korean, Arabic, Hindi, and Vietnamese.
Choose the target network, such as Instagram or Facebook, so tone and formatting match where the post will appear.
Generated captions can be copied immediately and pasted into the social app of your choice.
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.
AI captions and edits that turn raw footage into viral shorts in minutes
AI captions for your photos in seconds, in 14+ languages
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
