## 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

## Selection GPT

Selection GPT is a lightweight Chrome extension designed to remove friction from reading and studying online. Instead of copying text into a separate chat window, you simply highlight a passage on any web page and use the extension's floating controls to send it to ChatGPT. The extension ships with one-click buttons for the two most common tasks - generating a concise summary and producing a review quiz - plus a custom prompt option for anything else you need.

A defining characteristic of Selection GPT is that it is bring-your-own-key. Rather than bundling a paid AI subscription, it asks you to paste an OpenAI API key obtained from platform.openai.com. That means requests are billed directly by OpenAI at standard API rates, and you decide how much you want to spend. The developer states that the tool does not collect or sell your data, and the extension itself is only about 14 KB, so it stays out of the way.

The trade-off of this approach is that it is aimed at users comfortable managing an API key and OpenAI account. There is no paid tier, no account on the developer's side, and no bundled credits. For students, researchers, and professionals who already have an OpenAI key, it is a fast, private, and inexpensive way to add instant comprehension and self-testing tools to everyday browsing.

**Pricing & Plans:** Free extension. You pay OpenAI directly for API usage based on your own OpenAI account.

- **One-click summaries:** Highlight any passage and generate a concise summary without leaving the page.
- **Review quiz generator:** Turn selected text into a quick quiz to test your understanding of the material.
- **Custom prompts:** Ask ChatGPT your own questions or give instructions about the selected text.
- **Bring your own OpenAI key:** Use your personal OpenAI API key so requests are billed at standard API rates.
- **Lightweight and privacy-minded:** About 14 KB with no declared data collection or third-party selling.

**Strengths:** Simple, focused workflow with one-click actions; No subscription - you pay only for the OpenAI usage you make; Very small footprint with no declared data collection; Works on almost any web page text

**Limitations:** Requires you to set up and manage your own OpenAI API key; Only available on Chrome-based browsers; Feature set is basic compared with paid all-in-one assistants
