## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini

## 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
