## 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

## GmailMate

GmailMate takes the friction out of everyday emailing. Once installed in Chrome, it adds AI reply generation to the Gmail web interface, so a user reading a message can produce a polished, context-appropriate response in a couple of clicks. The extension offers tone presets such as friendly, casual, and professional, which makes it practical for the very different registers people need when writing to friends, colleagues, or clients.

Beyond single replies, GmailMate supports review of your own drafts — improving wording and personalization — and a reusable signature block that is appended automatically. Users who deal with a backlog can select several messages and generate replies to them in one pass, which turns a tedious inbox session into a short review-and-send routine.

The product is a small, focused utility rather than a full email platform. It is hosted on the Chrome Web Store under the developer Sai Charan Sudi, and by the developer's own disclosure it does not collect or sell user data. Because it relies on third-party model access, output quality depends on the ChatGPT service you are signed into, and you should still review any AI-drafted message before sending it.

**Pricing & Plans:** Freemium. The extension is free to install from the Chrome Web Store; the listing does not publish a paid tier, so any cost is limited to whatever ChatGPT access you already use.

- **AI reply generation:** Draft replies to the email you are reading directly inside Gmail, with no copy-pasting into a separate chat window.
- **Tone presets:** Choose between friendly, casual, professional and other styles so the same message can be reshaped for different recipients.
- **Draft review and polish:** Run your own written email through the assistant to improve clarity, wording and personalization before sending.
- **Signature block:** Save a standard signature once and have it appended automatically to outgoing mail.
- **Multiple replies at once:** Select several messages in your inbox and generate responses for all of them in a single pass.

**Strengths:** Free to install and very small, so it adds no noticeable browser overhead; Tone presets make it easy to match the register of the person you are writing to; Handles several emails at once instead of one reply at a time; Developer declares no collection or sale of user data

**Limitations:** Requires a working ChatGPT session, so it inherits that service's availability and limits; Extension has been updated only rarely, and recent reviews are limited; Generated text still needs a human read-through before it goes out
