Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026β€”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 endpointsβ€”`deepseek-flash` and `deepseek-v4-pro`β€”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 [Profile (Markdown)](https://openaitools.app/tool/deepseek.md) ## Messaging Assistant πŸš€ Messaging Assistant πŸš€ keeps its feature list short and practical. The first function is reply generation for WhatsApp: place your cursor in a conversation, press Ctrl+Q, and the extension proposes a message you can send or edit. If you would rather not trigger it manually every time, the settings include an auto-generation toggle. The second function is rewriting: select any text on a page, press Alt+R or use the right-click menu item, and the selection is rephrased to sound better and shorter. Architecturally it is unusually simple, and the developer is open about it. According to the listing, the extension stores and reads none of your data and has no backend at all β€” it talks directly to the OpenAI API. That removes a middle server from the picture, though it does mean the extension needs your own API access or a key configured in its settings to function, and it also means the quality of the output depends on the model you point it at. The listing notes the prompts are optimized for English but will still work for other languages. The extension is published by Growing Pies, last updated in December 2024, is free to install, and had a very small install base at the time of review. Treat it as a handy utility rather than a supported commercial product: there are no ratings yet, so there is little independent feedback to go on. **Pricing & Plans:** Free to install with no in-app purchases listed. If the extension connects directly to the OpenAI API, any API usage costs are billed by OpenAI under your own account. - **WhatsApp reply generation:** Press Ctrl+Q inside a WhatsApp Web conversation to have an AI-drafted reply appear, ready to send or edit. - **Optional auto-generation:** Turn on auto-generation in the extension settings if you want replies suggested without pressing the shortcut each time. - **Selected-text rewriting:** Highlight any text and press Alt+R, or right-click and choose 'Rewrite Selected Text', to get a clearer, more concise version. - **No backend, direct API calls:** The developer states the extension has no server of its own and communicates straight with the OpenAI API, with no data stored or read. - **Keyboard-first and low friction:** Two shortcuts and one context-menu item cover the whole feature set, so there is no interface to learn. **Strengths:** Free to install with no in-app purchases listed; Two genuinely useful shortcuts: reply generation and text rewriting; Developer states there is no backend and no data storage, only direct OpenAI API calls; Works on WhatsApp Web without needing a separate app or account **Limitations:** Very low install count and no user ratings, so reliability is hard to verify independently; Last updated December 2024, so it may lag behind changes in WhatsApp Web; Direct OpenAI API usage means you likely need your own key and to pay API costs; Prompts are tuned for English; other languages may produce weaker results [Profile (Markdown)](https://openaitools.app/tool/messaging-assistant.md) ## Frequently Asked Questions ### How do DeepSeek and Messaging Assistant πŸš€ compare in monthly traffic?
