## BigModel

BigModel is Zhipu AI's developer-facing platform, offering API access to the company's GLM series of large language models and a broad set of multimodal capabilities. Instead of juggling separate vendors, teams can call text generation, vision-language understanding, OCR, speech recognition, speech synthesis, image generation, and video generation endpoints from one account and one set of credentials.

Beyond raw model access, the platform targets application builders. It includes an agent framework, MCP service support, knowledge-base tooling for retrieval-augmented generation, model fine-tuning workflows, and a model playground for quick testing in the browser. There are also adjacent offerings such as an AI coding assistant and visual/low-code building experiences aimed at teams that want to ship without heavy ML engineering.

For organizations with stricter requirements, BigModel supports private instance deployment and on-premise options, alongside token-based pay-as-you-go and enterprise contracts. This makes it a fit for both individual developers prototyping on a budget and enterprises that need data to stay inside their own infrastructure.

**Pricing & Plans:** BigModel follows a freemium, token-based model: new users typically receive free trial credits, then pay-as-you-go for API usage by tokens consumed. Larger volumes, private instance deployment, and on-premise installations are arranged through contact-for-pricing enterprise agreements. Always confirm current rates on the official pricing page.

- **GLM text and multimodal APIs:** Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
- **Agent and MCP support:** Build tool-using agents and expose or consume MCP services to connect models to external systems.
- **Knowledge base and RAG tooling:** Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
- **Fine-tuning and playground:** Tune models on your data and prototype prompts interactively in the browser before shipping.
- **Private and on-premise deployment:** Run models in a private instance or on your own hardware for data-residency and compliance needs.

**Strengths:** Broad model coverage, from LLMs to vision, speech, and video, under one platform; Officially backs the GLM family, so model documentation and updates are first-party; Supports private and on-premise deployment for strict data requirements; Includes agent, knowledge-base, and fine-tuning tooling beyond raw API access

**Limitations:** Pricing and documentation are primarily Chinese-first, which can slow English-only teams; Some enterprise capabilities require sales contact rather than transparent self-serve pricing; Token costs can grow quickly for high-volume multimodal workloads

## UserAPI.ai

Midjourney has no official public API, so teams that want image generation inside their own products usually need a workaround. UserAPI.ai fills that gap as an independent, unofficial API: it accepts a prompt and returns generated images, exposing the familiar Midjourney methods as REST endpoints you can call from your backend.

There are two ways to generate. With your own Midjourney account you add a Discord token once and pay Midjourney for your plan; UserAPI access costs $0.04 per request or $25 per month, and this route is cheaper above a few hundred images a month and supports speed mode and multiple accounts. With UserAPI Cloud you need no Midjourney subscription and no Discord token — Generations run on UserAPI's accounts at $0.08 per image, with failed tasks refunded automatically, which is a fast way to test.

The service supports the core Midjourney toolkit: Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint. It ships documentation, code examples for Python, Node.js and PHP, and no-code integrations for n8n and Make.com. It is explicitly not affiliated with Midjourney Inc., so evaluate the account and reliability risks of unofficial access before building it into production.

**Pricing & Plans:** UserAPI.ai offers a free pack of 50 requests with no card. Using your own Midjourney account costs $0.04 per request or $25 per month (or $67.50 per quarter and $246 per year), while UserAPI Cloud runs on UserAPI's accounts at $0.08 per image, a 60% discount off the $0.20 launch rate, starting from $3 (about 37 images), with failed tasks refunded automatically.

- **Full Midjourney method coverage:** Call Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint through a REST API for scripted image generation.
- **Cloud generation without Discord:** Generate without a Midjourney subscription or Discord token by running on UserAPI Cloud accounts, with failed tasks refunded automatically.
- **Multi-account admin panel:** Manage multiple image generation accounts, schedules and keys from a single admin panel.
- **Code examples and no-code integrations:** Ready code samples for Python, Node.js and PHP, plus official integrations for n8n and Make.com automations.
- **Free pack and flexible plans:** Start with a free pack of 50 requests and move to pay-per-request or monthly plans as volume grows.

**Strengths:** Brings Midjourney image generation into your own app without an official API; Cloud option works with no Midjourney subscription and no Discord token; Covers the main Midjourney methods, including Inpaint, Blend and Animate; Code examples for Python, Node.js and PHP plus n8n and Make.com integrations

**Limitations:** It is an unofficial API and is not affiliated with Midjourney, so it depends on platform behavior it does not control; Using your own Midjourney account still requires a Midjourney subscription and a Discord token; Because it relies on Discord accounts, automated usage carries account-risk considerations; Cloud pricing is per image and can add up at high volume
