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.

Unfiltered large language model inference, with a free tier and API access
No content filtering and no behavioural guidelines are applied on the provider side. mancer runs the models and returns whatever they generate, leaving the choice of what to prompt to the user.
Access a capable model at no cost for everyday use, and move to paid models when you need faster response times, larger parameter sizes or stronger general ability.
An OpenAI-compatible text-generation API means chat front-ends such as SillyTavern and other OpenAI-style clients can point straight at mancer without bespoke integration work.
Sign-up, model selection and usage are a short, three-step flow designed so you can get a key and start prompting quickly rather than working through a heavy onboarding process.
