## 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

## SmartPDFs

SmartPDFs does one job and does it simply: it turns a PDF into a short, readable summary in seconds. The interface is minimal — upload a PDF, choose a language and generate. The result is a concise overview that helps you decide whether a document is worth a full read or pulls out the essential points when you are short on time.

Because it is free and open source, SmartPDFs is approachable for casual readers and developers alike. The summaries are produced by Llama 3.3 running on Together AI, a large language model that captures the main arguments, findings and conclusions of the source text. The language selector lets you generate the summary in a language you prefer, which is useful when working across documents written in other languages.

SmartPDFs suits anyone who handles a lot of PDFs — students working through reading lists, professionals triaging reports and papers, or teams that want a fast, shareable overview of a long document. It works best with text-based PDFs; scanned documents without extractable text may not summarize reliably, and like any summarizer the output depends on the source content.

**Pricing & Plans:** Free. SmartPDFs is free to use, with no paywall for generating PDF summaries. It is also open source.

- **Instant PDF summaries:** Upload a PDF and get a concise summary in seconds, so you can understand the gist without reading the full document.
- **Language selection:** Choose the language for the summary before generating, making it easy to read a document in your preferred language.
- **Clear, shareable summaries:** Summaries are clean and easy to share with colleagues or classmates as a quick overview of a document.
- **Open source:** SmartPDFs is open source, with its code published on GitHub for anyone to inspect or self-host.
- **Powered by Llama 3.3 on Together AI:** Summaries are generated by Llama 3.3 running on Together AI, a modern large language model.

**Strengths:** Completely free with no paywall; Very simple three-step flow: upload, choose language, generate; Open source and reviewable on GitHub; Language selection makes summaries readable across languages

**Limitations:** Only handles PDF uploads, not other document formats; There is no stated account system or long-term document library; Summaries depend entirely on the quality of the source PDF text
