## 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

## Defained

Defained targets the everyday friction of working with large language models: prompts that live scattered across documents, notes and chat history. Instead of hunting for text and pasting it in, you keep a structured prompt library and pull any entry into the active chat window with one click. The extension sits alongside ChatGPT, Gemini, Claude and Perplexity, so it fits into your existing workflow rather than replacing it.

The organizational layer is deliberately simple. You can link a Google Sheet as your prompt source, which means edits happen in a spreadsheet you already control, and you can search, filter by category and mark favourites once the library grows. A template gallery of 50+ prompts gives new users something useful before they build their own collection.

Defained is a free-to-install Chrome extension published by LM Media. It is a focused productivity utility rather than a full prompt-engineering suite, so it suits people who mainly want fast reuse of prompts across several chat tools.

**Pricing & Plans:** Defained is free to install from the Chrome Web Store, with a built-in gallery of 50+ free prompts. The listing is categorized as freemium. No paid tiers are advertised on the store page.

- **One-click prompt insertion:** Pick any stored prompt and send it straight into the active ChatGPT, Gemini, Claude or Perplexity input field without copying and pasting.
- **Google Sheet prompt library:** Connect a Google Sheet so your prompt library stays editable in a familiar spreadsheet and syncs with the extension.
- **Search, filters and favourites:** Search your prompt collection, filter entries by category and star the ones you rely on most.
- **50+ free prompt templates:** Start quickly with a built-in gallery of more than 50 ready-made prompts that require no setup.
- **In-context overlay:** Runs as a lightweight browser extension panel, so the prompt manager sits next to the AI chat you are already using.

**Strengths:** Removes repetitive copy-pasting across four major AI chat tools; Prompt library can be managed in a familiar Google Sheet; Includes 50+ free templates for immediate use; Lightweight extension that stays inside the tools you already use

**Limitations:** No user ratings yet on the Chrome Web Store listing; Prompt library connection depends on a Google Sheet workflow, which some users may find limiting; Last update was July 2024, so feature velocity appears slow; Only works inside supported chat interfaces rather than any web app
