## 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

## Doclingo

Doclingo is an online translation platform focused on content that ordinary translators handle badly: formatted documents, scans and images. Instead of returning a wall of plain text, it rebuilds the translated content inside the original page structure — headers, columns, tables and image captions stay where they were. PDF, Word, Excel, PowerPoint and image files such as PNG, JPG and WEBP are all supported, so contracts, research papers, product manuals and design drawings come back in a form you can still use.

The service pairs a layout engine with selectable AI translation engines, which means you can pick a model per job and watch your usage. OCR handles scanned pages and text baked into images, and every result can be reviewed in a bilingual view that places the translation under or beside the source. A built-in editor lets you fix terminology, and a glossary feature keeps recurring industry terms consistent across long projects. For collaborators and developers there is also a batch translation API.

Beyond the core document flow, Doclingo ships a browser extension for Chrome and Edge that translates WhatsApp and Telegram Web messages in place, a dedicated image translation mode with strict-layout and readability-first options, and a document chat that lets you ask questions about an uploaded file. There is a genuinely free tier with no signup required for standard translations, plus a paid PDF Pro track aimed at high-fidelity restorations and heavy OCR workloads, so the tool serves both occasional students and professional localization teams.

**Pricing & Plans:** Freemium-style with a no-signup free tier for standard document translation and a paid 'PDF Pro' tier for high-fidelity restoration, advanced OCR and larger volumes; an enterprise/API option exists. Check the site for current plan limits.

- **Layout-preserving translation:** Translated text is redrawn into the original document structure, keeping columns, tables, headings and images in place instead of producing a stripped-down text dump.
- **OCR for scans and images:** Recognises text in scanned PDFs, screenshots, photos, menus and posters, then translates it and puts it back into the image at the same position, size and colour.
- **Bilingual side-by-side output:** Read the source and the translation together, which makes reviewing terminology in contracts and academic papers far faster than flipping between files.
- **Wide format and language support:** Handles PDF, Word, Excel, PowerPoint and common image formats across 90+ languages, with batch processing for multiple files at once.
- **Browser extension for chat translation:** The Chrome/Edge extension translates WhatsApp Web and Telegram Web messages inline and can translate your own replies before sending them.

**Strengths:** Layout and formatting are genuinely preserved, which is the main weakness of most free translators; OCR handles scanned documents and text inside images, not just clean digital files; Free tier works without creating an account, lowering the barrier to trying it; Extras like bilingual view, glossary, online editing and chat translation make it a workspace rather than a one-shot converter

**Limitations:** Very large or complex files can take a while to process, and heavy OCR use pushes you toward the paid tier; The browser extension is desktop-only and cannot be installed on phones; Translation quality still varies by language pair and by which AI engine you select
