## 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

## Maildep

Maildep combines conventional mail server hosting with agentic AI processing. Each mailbox is a normal IMAP/SMTP account that works with familiar clients such as Outlook, Gmail, Thunderbird, and Spark, complete with SPF, DKIM, DMARC, TLS/SSL, spam filtering, and auto-discovery. What sets it apart is what happens when mail arrives: the server runs it through a large language model to summarize the message and pull out embedded reports, meetings, tasks, invoices, and bills, and it can generate draft replies too. Maildep estimates this automation can save staff roughly two hours a day.

The platform is deliberately model-agnostic. You supply your own API keys for OpenAI, Azure, Anthropic, or DeepSeek, or wire in models from Groq, SambaNova, OpenRouter, and even a self-run Ollama instance. Usage of those APIs is free of charge on Maildep's side; if you would rather not manage your own keys, you can buy token plans that are shared across your mailboxes. Administrators get per-mailbox toggles, custom prompts, ignore lists, and performance and token-usage reports so AI behavior stays under control.

Hosting is delivered from six data centers across the US, UK, EU, Japan, Singapore, and India so you can keep data within a chosen jurisdiction. Plans range from a low-cost tester mailbox up to large multi-domain business accounts, and for organizations that want full control there is a semi-self-hosted small-business tier and a fully self-hosted, Kubernetes and container-based installation with a management control panel and a year of maintenance.

**Pricing & Plans:** Freemium with a free trial and paid tiers. Mailbox hosting runs from $0.50/month (5 GB Tester) through $2.5/month (Starter, 25 GB), $12.5/month (Professional, 120 GB), and $75/month (Ultimate, 700 GB), with a 15-day free trial and no payment required to start. Small-business semi-self-hosting is $150/month and full self-hosting is $1,500 per installation. AI token plans are sold separately ($1 for 2M, $3 for 5M, $8 for 10M tokens), while using your own API keys is free; 200,000 free ChatGPT tokens are included per mailbox. Extra storage is $1/GB per month and region changes cost $80.

- **AI-connected IMAP and SMTP hosting:** Standard business email with IMAP/SMTP, SPF, DKIM, DMARC, TLS/SSL, spam filtering, and automatic mail server discovery that works with Outlook, Gmail, Thunderbird, and Spark.
- **Automatic extraction on arrival:** Incoming messages are automatically summarized and mined for reports, meetings, tasks, to-dos, and invoices and bills as they arrive.
- **Bring your own AI model:** Point mailboxes at OpenAI, Azure, Anthropic, DeepSeek, Qwen, Groq, SambaNova, OpenRouter, or your own Ollama models, using your own API keys.
- **Six regional data centers:** Choose from six data centers in the US Central, United Kingdom, European Union, Japan, Singapore, and India.
- **Granular mailbox-level controls:** Enable or disable AI per mailbox, add custom prompts, maintain an ignore list, and review AI model performance and token usage reports.

**Strengths:** True business email hosting, not just an AI layer on someone else's mailbox; Model-agnostic: use your own OpenAI, Azure, Anthropic, DeepSeek, or local Ollama keys; Automatic summarization and extraction of reports, meetings, tasks, and invoices on arrival; Six regional data centers for jurisdictional control, plus fully self-hosted option

**Limitations:** AI features require you to supply your own API key (OpenAI, Azure, Anthropic, DeepSeek, etc.) or buy token plans separately; Setup assumes you can manage DNS records for your own domain and understand mail server concepts; Self-hosting and small-business tiers carry significant up-front commitments ($150/month or $1,500 per installation); Regional data center changes and extra storage incur additional fees, which can add up
