## 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

## TextSight

Most AI-detector sites stop at a percentage. TextSight is built as a workflow instead: you detect, you fix the flagged sentences with the built-in humanizer, and you re-run the check in the same tab to see whether the score actually improved. That loop is the core of the product, and it is why detection and rewriting live under one roof rather than in two separate subscriptions.

Under the hood there is a multi-model detector trained on output from ChatGPT, Claude, Gemini, Llama and Mistral, a 0–100 Humanization Score, and a rewrite engine that only touches the passages you flag. Around that core sit roughly twenty smaller writing utilities — grammar, readability, paraphrasing, summarisation, translation — plus a Chrome extension and add-ons for Word and Google Docs.

TextSight is unusually forthcoming about the limits of detection. It published a benchmark of 1,180 human-written academic papers from 2018, before GPT-3 existed, and reports a 5.85% false-positive rate on that corpus, with the dataset, analysis script and methodology downloadable. The company explicitly labels this its own testing rather than independent third-party validation, and tells educators to treat any score as one signal rather than proof.

**Pricing & Plans:** Freemium. The free tier gives 3 actions a day (around 1,000 words per scan without an account, ~1,500 with one; 260 words per humanization) using the same detector as paid plans. Starter is $9.99/mo, Pro $19.99/mo, Business $39.99/mo and Enterprise $79.99/mo, with annual billing discounting roughly 63%. Lower tiers include 20 daily actions and 40,000 humanizer words a month; Pro adds file upload and 5,000 API calls; higher tiers add team seats, bulk scanning, SSO and more API volume. No card is required to start, and plans can be changed or cancelled from settings.

- **Sentence-level AI detection:** Every sentence gets its own AI confidence score and colour code inside your text, so you can see which lines to fix instead of reacting to one blunt overall verdict. Sentence-level detail starts on the Starter plan.
- **Humanization Score:** A 0–100 score that rises as your writing becomes more natural, recomputed on every scan so you can watch the number move as you edit.
- **Targeted AI humanizer:** The humanizer rewrites only the passages that read as AI-written, keeping your meaning and tone. Free accounts get around 260 words per rewrite; paid plans add thousands of words a month plus Advanced, Business and Casual modes.
- **Detect, humanize, recheck in one place:** Detection, rewriting and re-scoring happen in one window. After a humanize pass you recheck the same text and compare the before-and-after AI percentage side by side.
- **Writing toolset and integrations:** About 20 supporting tools cover grammar, readability, paraphrasing, summarisation and translation, with a Chrome extension for right-click scanning of any text in your browser and add-ons for Word and Google Docs.

**Strengths:** Detection, humanizing and rechecking all happen in one window with no copy-paste between tabs; The free tier runs the same detector as the paid plans, so accuracy is not paywalled; Sentence-level flags point at specific lines rather than giving a single opaque score; The company publishes its own false-positive benchmark, dataset and methodology

**Limitations:** \"Humanization Score\" and AI probability are its own detector's numbers, so they are not an independent verdict; Heavy users (bulk files, folder libraries, team seats) must move to mid or top tiers; Detector accuracy is calibrated mainly on English text; other languages are weaker; False-positive testing is self-run and the vendor explicitly says it is not third-party validation
