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.
Upscale blurry photos to 4K and 8K with AI
AI models analyze the image and reconstruct detail to raise resolution while keeping textures and edges natural rather than artificially sharpened.
Purpose-built modes for standard photos, portraits, anime and art, face restoration and scratch restoration let you match the tool to the image.
Upload up to 5 images at once on the free tier, with larger batches available on paid plans for high-volume workflows.
Non-destructive cleanup tools include background removal, object removal, watermark removal, colorization, photo restoration and an AI photo editor.
Free / Open-sourceDelivers exceptional open-weight reasoning performance at very low cost, but lacks BigModel's broad enterprise multi-modal agent building suite.
