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.

An open-source vision model for captioning, Q&A, OCR and detection.
Generate natural-language descriptions of any image in a few lines of Python, useful for accessibility, asset tagging and cataloguing.
Ask questions in plain language about what is in a photo — objects, counts, text, context — and get concise answers back.
Read printed text, signage and documents straight from images, supporting OCR workflows without a separate pipeline.
Detect, locate and count objects and people in an image, with pointing and gaze-style understanding supported by the model family.
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.

Free / Open-sourceGoogle's family of lightweight, open-weight AI models


Ultra-fast AI inference on the LPU and LPX platform

SpecialistOne API for 1,500+ production-ready generative media models

Together AI is the AI Native Cloud — a full-stack platform for running, fine-tuning and training open-source models. It spans serverless inference APIs, dedicated endpoints, GPU clusters, post-training and storage, all backed by in-house systems research.
