## 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

## DetectGPT - Detect ChatGPT Content

DetectGPT adds an AI-content check directly to your browsing workflow. Once installed, you can open the extension on any page and it will scan the visible content for signs of machine authorship, or you can copy a block of text, right-click, and choose "Scan with DetectGPT" for a targeted check. There is also a manual paste area inside the extension for quick one-off checks.

The original tool was trained to recognise output from widely used natural language models, including ChatGPT, GPT-3.5, GPT-3, GPT-J, GPT-NEO and GPT-2. Its published figures cite accuracy around 94% on raw GPT-3 output, and it openly states that detection is not perfect — false positives and missed detections are possible, so results are best read as probabilities over a larger sample rather than as proof about a single paragraph.

The extension needs no account or sign-up and is free to install, which makes it easy to drop into a quick verification routine: checking a guest post before publishing, reviewing copy submitted by a freelancer, or sanity-checking content you find while researching. Because it is a browser extension, it fits naturally into editorial and SEO workflows where content is reviewed in tabs rather than in a separate dashboard.

**Pricing & Plans:** Free to install and use as a browser extension; no account or sign-up required. The developer, Originality.ai, also sells paid AI-detection and plagiarism-checking services separately.

- **One-click page scanning:** Open the extension on any site and it scans the page's content for signs of AI authorship without extra setup.
- **Right-click text checks:** Select a passage, right-click, and choose "Scan with DetectGPT" to test just the text you care about.
- **No account needed:** Install and start scanning immediately — there is no sign-up, login, or credit system to manage.
- **Trained on popular models:** Built to recognise output from widely used models including ChatGPT, GPT-3.5, GPT-3, GPT-J, GPT-NEO and GPT-2.
- **Human-readable guidance:** The listing also explains manual tells of AI text — repetitive structure, flat tone, and factual slips — to aid your own judgement.

**Strengths:** Free to install with no account, login, or usage credits required; Works directly in the browser on live pages rather than requiring copy-paste into a separate site; Backed by Originality.ai, a company specialising in AI detection and plagiarism checking; Flexible checking options: full-page scan, right-click selection, or manual paste

**Limitations:** Detection is not conclusive — the developer notes possible false positives and missed cases; The extension listing has not been updated since April 2023, so its model coverage may lag newer AI writers; Best treated as a signal, not proof, when making decisions about a piece of content
