## 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

## T&C Reader — Know What You Agree To

T&C Reader addresses a familiar problem: almost nobody reads the terms and privacy policies they agree to. The extension scans the policy on whatever site you are visiting, produces an A–F letter grade, and breaks that grade into four sub-scores covering data protection, legal compliance, readability and fairness. Instead of vague warnings, it points to the specific sentence behind each finding so you can verify the judgment yourself.

The extension flags a wide set of common red flags, including data selling, forced arbitration, class-action waivers, auto-renewal traps, trials that convert into charges, no-refund policies, AI training on your content, and broad rights over user posts. You can also ask direct questions such as "Can I get a refund?" or "Do they sell my data?" and receive short answers quoted from the policy. Summaries and answers are available in English, Amharic, Arabic, French, Spanish, Italian, German and Portuguese, and a small badge appears on sign-up forms and policy pages so you know a grade is available before you click accept.

T&C Reader is free and works immediately after installation with no account. Privacy is treated as a first principle: browsing history is not stored, grade lookups send only a bare domain, and analysis runs on public policy text. Users who prefer their own provider can supply a Google Gemini, OpenAI or Claude API key, which is encrypted in the browser and never transmitted to the developer. The extension also strips hidden text designed to trick AI reviewers and derives grades from fixed rules applied to cited text rather than model sentiment. It explains policies but is not legal advice.

**Pricing & Plans:** Free. No account or payment required to use the full feature set; an optional account syncs settings, checked sites and chat history across devices.

- **A–F policy grading:** Every Terms or Privacy page gets a letter grade split into four scores: data protection, legal compliance, readability and fairness.
- **Red flags explained simply:** Detects and explains data selling, forced arbitration, class-action waivers, auto-renewal, no-refund terms and AI training on your content.
- **Proof for every claim:** Tap any finding to see the exact sentence — or jump straight to it on the page — so grades are verifiable rather than opaque.
- **Ask the policy anything:** Ask questions like "Do they sell my data?" and get short answers that quote the policy directly.
- **Bring your own AI key:** Optionally use your own Google Gemini, OpenAI or Claude key, encrypted locally and never sent to the developer.

**Strengths:** Free with no account or sign-in required for core features; Every claim is backed by a link to the exact source sentence; Local processing discipline — no browsing history stored, only bare domains sent; Works with your own Gemini, OpenAI or Claude key if you prefer

**Limitations:** Coverage depends on the extension correctly detecting a policy page; Not legal advice, so high-stakes contracts still warrant professional review; Requires an account to sync settings and chat history across devices
