## 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

## re:write

re:write is a small, focused writing assistant delivered as a Chrome extension. Its purpose is narrow and practical: when you are drafting an email, a chat message, or a short document, you can send the text to re:write and get back a polished version. It also checks grammar, so it improves both phrasing and correctness rather than only swapping words around.

Unlike full-featured AI writing suites, re:write leans on a browser extension approach. There is no sprawling editor to learn and no plan tiers to compare — you install it, invoke it where you write, and accept the improved text on the spot. That makes it best suited to people who spend their day in web apps like email clients and messaging tools and want a quick cleanup button rather than a whole new writing environment.

Under the hood, the extension is built on the ChatGPT API and described as using a GPT-3.5-turbo-era model. That keeps it responsive and cheap to operate, though it means re:write is not competing on the bleeding edge of writing quality. The project is positioned as free, and its website keeps things simple, with a download link, a description, and a handful of user testimonials rather than a deep feature list.

**Pricing & Plans:** Free. The website presents re:write as free to download and use, with no paid plan advertised and no pricing page. Because newer API costs could change over time, confirm current terms on the site; no price figures are published.

- **One-click rewriting in place:** Highlight or focus text and re:write produces a cleaner, better-worded version without you leaving the tab or app you are writing in.
- **Grammar checking:** Alongside rewriting, the extension checks grammar so phrases and sentences come out correct, not just differently phrased.
- **Powered by the ChatGPT API:** re:write is powered by the ChatGPT API, giving you access to a capable large language model directly from your browser.
- **Chrome extension convenience:** Sent as a lightweight Chrome extension, it lives in your browser and is available on any page or text field you are working in.
- **Free to use:** The tool is offered at no cost, which makes it easy to keep installed for daily email and message drafting.

**Strengths:** Completely free with no advertised plan tiers; Fast, one-click rewriting that works inside the browser tab you're already using; Also checks grammar, not just rephrasing; Powered by the ChatGPT API, so output quality is a clear step above basic synonym tools

**Limitations:** Only distributed as a Chrome extension, so it is not usable in Firefox, Safari, or as a standalone web app; Built on an older GPT-3.5-turbo-era API, so output quality is below the latest generation of writing models; Minimal controls — one-click rewriting leaves little room for tone, length, or audience tuning; The marketing site is thin, with no changelog, changelog page, or documentation for advanced use
