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.
One REST API for LLMs, image generation and speech models
One API covers language models like Mistral and Llama, Stable Diffusion image generation, Whisper speech-to-text and text-to-speech.
TextSynth uses its own inference code rather than off-the-shelf stacks to run faster on standard GPUs and CPUs, aiming to reduce cost per request.
A browser playground lets you try each model, tweak parameters and evaluate output quality before writing any integration code.
Everything is exposed over HTTP, so it can be wired into existing apps, scripts or internal tools without a heavy SDK.
