## 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

## Text Assistant

Text Assistant is a Chrome extension for people who want OpenAI's models available anywhere they read or write on the web. Rather than switching to a chat tab, you select text on the page and invoke the extension to get explanations, grammar and spelling corrections, or a ready-to-send reply.

Its most distinctive feature is chart creation: you can select structured text and have the model return a chart, which turns pasted numbers or lists into a quick visual without a spreadsheet. The other parts of the workflow cover comprehension and writing quality, so it works as a general-purpose reading and drafting aid.

Text Assistant is bring-your-own-key. You sign up for an OpenAI API key, paste it into the extension settings, and then pay OpenAI for what you use. The extension itself is free, published by an individual developer, and last updated in 2023, so its feature set is simple rather than expansive.

**Pricing & Plans:** Free to add from the Chrome Web Store. Access to the AI features requires your own OpenAI API key, and OpenAI bills you directly for usage.

- **Explain selected text:** Highlight any confusing passage and ask the model to explain it in plain language.
- **Proofreading and suggestions:** Get grammar, spelling, and clarity suggestions on a selection so your writing reads correctly.
- **Reply generation:** Generate a natural-language reply to a message or email based on the text you selected.
- **Chart creation:** Turn selected data or list text into a simple chart to visualize it quickly.
- **Bring your own API key:** Your OpenAI API key is entered in the extension settings so all requests run through your own account.

**Strengths:** Explains, proofreads, replies, and charts from a single selection; Works on any web page without leaving the tab; Free extension with no subscription of its own; Simple setup: add your OpenAI key and start selecting text

**Limitations:** Requires an OpenAI API key and a separate OpenAI account/billing; Last updated in April 2023 and still at version 0.2; No user ratings and a modest install base; English-only interface and limited built-in formatting options
