## 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

## PDNob PDF Editor

PDNob PDF Editor is aimed at people who work with PDFs daily and want the core toolset plus a layer of automation. The suite covers reading, text and image editing, annotation, page organization, forms, signing, protection and compression, and it handles batch conversion between PDF and more than 30 formats including Word, Excel, PowerPoint, EPUB, images and PDF/A while preserving the original layout.

Its AI layer is what differentiates it from a classic editor. An AI PDF agent can summarize long documents, answer questions about their contents with source-backed responses, and translate PDFs. The OCR engine, built with Tenorshare's ADRT technology, turns scans and skewed or low-quality pages into editable, searchable PDFs across 16+ languages, with automatic deskewing and denoising beforehand. Tenorshare also touts a self-developed PDFium-based engine that opens large documents quickly without lag.

The product spans Windows 10/11, macOS and an iOS app, and is available as a free download alongside a lifetime license option and team pricing. Because it belongs to the wider Tenorshare PDNob family, it pairs naturally with the company's image-to-text and image translator utilities for a document workflow that stays in one ecosystem.

**Pricing & Plans:** Freemium with a free download, a discounted lifetime license option and separate team pricing; check the official page for current tiers, discounts and regional prices.

- **AI PDF agent:** Summarize long documents, ask questions and get source-backed answers, or translate entire PDFs without leaving the app.
- **Full PDF editing:** Edit text, images, links and backgrounds, annotate, add watermarks, and organize pages by inserting, deleting, rotating, cropping or extracting them.
- **Batch conversion and OCR:** Convert between PDF and 30+ formats while keeping formatting, and turn scanned documents into editable, searchable PDFs in 16+ languages.
- **Fast engine and compression:** A self-developed PDFium-based engine opens 100+ page files quickly, and built-in compression keeps file sizes manageable for sharing.
- **Cross-platform access:** Use the Windows and Mac desktop apps or the iOS app to read, edit and manage PDFs wherever you are.

**Strengths:** Combines editing, conversion, OCR and AI assistance in a single application; OCR handles skewed and low-quality scans and outputs searchable text; Formatting is largely preserved during batch conversion; Available on Windows, macOS and iOS with a free download option

**Limitations:** The free download has functional limits, and many advanced AI and batch features sit behind the paid license; Some AI features depend on the vendor's service, so behavior may differ by region or plan; Advanced OCR on complex layouts can still need manual cleanup
