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.
Turn photos, logos and text into optical illusion art with AI
Upload any picture — portrait, product, pet — and the model rebuilds it as a hidden-shape optical illusion image.
Edges are extracted with a Canny detector and human keypoints mapped with OpenPose so the illusion keeps the subject's real contours.
Quotes, slogans and brand marks can be used as the hidden layer, with the AI painting a scene around those letterforms.
Buy 40, 100 or 500 credits in one payment; each credit produces one high-quality image with no watermark.
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 art generator and community with daily challenges and free credits
Free, unlimited AI image generation with top models — no login required
Free / Open-sourceSpecializes in serverless open-source model hosting and dedicated GPU clusters, but provides less native proprietary GLM model integration.
Free text-to-image art generation straight from your browser
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 AI design studio for logos, stickers, merch, and social graphics
