## 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

## tabOS

tabOS is a Chrome extension that reframes your browser's new tab as a small operating system for your work. Rather than being a one-trick tab manager, it bundles tab and group management with documents, notes, feeds and AI into a single surface. You install it from the Chrome Web Store, and from then on every new tab is a dashboard where you lay your open work out in the open instead of hunting through a strip of tabs.

The tab management layer is thorough: drag and drop to save or close tabs and groups, create and rearrange groups, layer groups into folders, discard tabs to free memory, pin and move tabs, and view everything in grid, column, list or tree layouts. Alongside it sits a real productivity stack — create documents with Markdown and syntax highlighting, take quick notes, run to-do lists and store code snippets and images, all without leaving the browser. There is also a feeds section for RSS, YouTube and Reddit.

The AI side is where tabOS leans into the ChatGPT branding. You can assemble custom-prompted AI helpers, chat with AI, use Vision AI for image recognition, and select among ChatGPT 3.5, 4.0 and Turbo. A sharing and collaboration layer supports shared folders, shared documents and live sessions, with global, open-tab and fuzzy search to find anything across tabs, bookmarks and cloud files. Pricing is freemium: a Free Plan covers the core, while Pro and AI Plus plans add extra cloud storage, AI sorting and automatic daily backups. It is developed by Aconiti interfaces AB, the same independent studio behind tabExtend, and is not an official Google product.

**Pricing & Plans:** tabOS uses a freemium model with in-app purchases. The Free Plan unlocks the core workspace features and can be started with an anonymous account. Pro and AI Plus plans add extra cloud storage, AI sorting capabilities and automatic daily backups; exact prices are shown in the Chrome Web Store and in-app.

- **Tab and group management:** Manage tabs and tab groups, drag and drop to save or close them, discard tabs to free resources, and organise everything in grid, column, list and tree views.
- **Documents and notes:** Create and edit documents, take notes, manage to-dos, store code snippets and use Markdown with syntax highlighting directly in the new tab.
- **AI helpers and assistants:** Assemble custom-prompted AI helpers, chat with AI, use Vision AI for image recognition and choose among ChatGPT 3.5, 4.0 and Turbo models.
- **RSS, YouTube and Reddit feeds:** Create and subscribe to RSS feeds, and follow YouTube and Reddit feeds, all from inside your new tab.
- **Search and organisation:** Search across tabs, bookmarks and cloud files with global, open-tab and fuzzy search, and keep data safe with automatic daily backups on paid plans.

**Strengths:** Combines tab management, documents, notes, feeds and AI in one surface; Solid tab workflow with groups, folders, discarding and multiple view layouts; Free Plan covers the essentials, with paid tiers for storage and AI sorting; Includes collaboration features like shared folders and documents

**Limitations:** Pro and AI Plus tiers are needed for extra cloud storage and AI sorting capabilities; It is a full workspace system, so there is more to learn than a simple tab-grouping add-on; AI features depend on the ChatGPT models the extension exposes, whose availability and behaviour can change
