## 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

## GoPDF

GoPDF is a web-based document platform aimed at people who need to handle PDFs without installing desktop software. The core toolset covers the routine jobs: editing text and images in place, filling and signing forms, adding or removing pages, headers and footers, search and replace, merging, protecting, cropping, and running OCR on scanned files. Conversion is handled both ways, including PDF to Word, PDF to JPG and HTML to PDF.

On top of those utilities, GoPDF adds AI features. AI Chat with PDF lets you ask questions about a document instead of reading it end to end, and the AI quiz builder turns source material into tailored questions — useful for teachers, trainers and students. An invoicing tool rounds out the set for small businesses that want to create and manage invoices alongside their documents.

Everything runs in the browser with no installs and no sign-up required for basic tasks, and there are mobile apps for converting PDFs on the go. The company states that files are protected with SSL encryption and are not stored beyond your session, and support is advertised as available around the clock. A free plan covers core features while premium plans unlock advanced tools and higher usage limits.

**Pricing & Plans:** Freemium. A free plan covers basic PDF tools with no installs or sign-up, while premium plans unlock advanced features and higher usage limits. The site also lists a refund policy, and pricing details are on the GoPDF pricing page.

- **AI chat with PDF:** Ask questions about a document and get answers drawn from its content, so long reports and contracts do not need to be read line by line.
- **Full editing and signing:** Modify text and images directly, add pages, headers and footers, use search and replace, and fill or sign forms with manual or image signatures.
- **Convert, compress and merge:** Convert between PDF, Word, JPG and HTML, shrink oversized files, merge or split documents and remove excess pages.
- **AI quiz builder and invoicing:** Generate tailored quizzes from source content and create, manage and send invoices from the same platform.
- **OCR and document protection:** Run OCR on scanned PDFs to make text searchable, and protect or crop documents before sharing them.

**Strengths:** Wide toolset that covers editing, conversion, signing, OCR and compression in one place; AI features such as PDF chat and quiz generation add real value beyond basic utilities; Works entirely in the browser with no installation and no sign-up for basic tasks; SSL encryption and session-based file handling are stated as defaults

**Limitations:** Advanced tools and higher limits sit behind premium plans, so heavy users will need to pay; Feature depth per individual tool is smaller than dedicated single-purpose desktop software; No offline workflow, since everything depends on the browser and an internet connection
