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.

Generative AI music platform and browser studio for creating full vocal songs, stems, and MIDI.
Generates complete, structurally coherent songs with verses, choruses, bridges, and realistic emotional vocal delivery from either a simple mood description or custom metatagged lyrics.
Provides Premier subscribers with an in-browser multi-track production environment featuring timeline editing, audio effects, parameter automation, and direct MIDI file export for downstream DAW workflows.
Splits generated or uploaded songs into isolated vocal, drum, bass, and melodic instrument stems, using generative reconstruction to minimize phase bleed and artifacts.
Allows creators to highlight a specific time range within a track to rewrite lyrics, fix pronunciation, or regenerate a musical transition without altering the rest of the arrangement.
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.
Generates complete songs and vocals from text prompts, offering robust tools for lyrics and instrumental customization.

SpecialistExcels at separating existing audio into isolated stems rather than generating original songs from scratch.

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

Free / Open-sourceSpecializes in serverless open-source model hosting and dedicated GPU clusters, but provides less native proprietary GLM model integration.
Creates full songs and beats from text prompts, offering a straightforward alternative for quick music generation.
Matches Suno's full-song generation quality with exceptional vocal clarity, though its interface handles extension workflows differently.

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.
