## 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

## Multilingual.top (Langsany)

Multilingual.top is a free, browser-based AI translation platform. Today that domain serves Langsany, a translator whose defining idea is privacy by architecture: instead of sending your sentences to cloud servers, it runs open-source Opus-MT neural models locally through WebAssembly. That means confidential contracts, medical notes, or internal emails can be translated without uploading them anywhere, and you can even verify it yourself in your browser's Network tab.

The tool spans far more than plain text. It handles whole documents and e-books (PDF, Word, PowerPoint, Excel, EPUB) while preserving layout and chapters, translates images and scanned PDFs using on-device OCR, and transcribes audio and video with Whisper to produce bilingual SRT or VTT subtitles with timestamps kept intact.

It is completely free, with no account, subscription, or daily quota. The main practical trade-offs are a 5,000-character limit per text request, a slower first run on older phones while the model downloads and compiles, and routing through English when translating between two non-English languages. Once the model is cached, translation works offline and responds instantly.

**Pricing & Plans:** Free: no account, subscription, or daily quota. Text translation is limited to 5,000 characters per request. Offline use requires the neural model and page resources to stay cached, and clearing site data removes the downloaded models.

- **Free text translation:** Type or paste text and translate it instantly in your browser, with automatic language detection, up to 5,000 characters per request and no daily quota.
- **Document & e-book translation:** Translate EPUB, PDF, Word, PowerPoint, and Excel files while keeping chapters, layout, and formatting intact.
- **Image & OCR translation:** Read text from images and scanned PDFs with on-device OCR and draw the translation back onto the picture.
- **Subtitle & speech translation:** Transcribe audio and video with Whisper in the browser and produce bilingual SRT or VTT subtitles that preserve timestamps.
- **Private, on-device engine:** AI processing happens locally with open-source Opus-MT neural models, so your content never leaves your device and works offline once cached.

**Strengths:** Completely free with no account, quota, or subscription; Strong privacy: translation runs on-device with no content uploads; Covers text, documents, images, subtitles, and speech in one tool; Works offline after the language model is cached

**Limitations:** Text translation is capped at 5,000 characters per request, so long articles must be split; First use on an older or low-memory device is slow while the model downloads and compiles; Translation between two non-English languages routes through English, which can soften nuance; Quality is a step below large cloud models for subtle, high-stakes writing
