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 [Profile (Markdown)](https://openaitools.app/tool/deepseek.md) ## ReplyGPT ReplyGPT is a lightweight Chrome extension created for people who want to stay visible on social platforms but find writing comments tedious. Once installed and connected to a ReplyGPT subscription, it places AI drafting tools directly inside the interfaces you already use — Facebook, LinkedIn, X/Twitter and Quora — so a reply can be generated without leaving the page. The workflow is prompt-based: you describe the style or message you want, and the extension produces a reply that you can edit before posting. The product is aimed at social media managers, sales and marketing professionals, community builders and creators who comment at volume. Rather than replacing human judgement, it speeds up the first draft so users can focus on the parts that actually need a personal touch. The extension is published by an independent developer and distributed through the Chrome Web Store. The Chrome Web Store listing shows a small but non-zero install base and a version history reaching 2024. The publisher requires a paid ReplyGPT subscription for use, so the free element is limited to installing the extension. Specific plan pricing is published on the ReplyGPT website rather than in the store listing. **Pricing & Plans:** Freemium-style access: the Chrome extension itself is free to install, but an active subscription on replygpt.com is required to generate replies. Current plan tiers and prices are shown on the ReplyGPT website. - **AI comment generation on four platforms:** Generate context-aware comment suggestions directly on Facebook posts, LinkedIn feeds, X/Twitter threads and Quora answers. - **Prompt-driven replies:** Type a short prompt describing the tone or angle you want, and ReplyGPT turns it into a ready-to-post reply. - **In-page drafting, no tab switching:** Drafts appear inline where you are already reading, so you never have to switch tabs or copy text between tools. - **Editable before you publish:** Suggestions are inserted as editable drafts, letting you adjust wording and voice before publishing. - **Chrome-native and privacy-conscious:** A lightweight Chrome extension that follows the developer's recommended data practices and does not sell user data. **Strengths:** Speeds up comment writing across four major social platforms from one extension; Prompt-based tone control lets you match the voice of each platform; Suggestions appear inline, so no copy-pasting between apps; Editable drafts keep a human in the loop before posting **Limitations:** Requires a separate paid subscription on replygpt.com before the extension is usable; Small user base and a very limited number of reviews, so community feedback is thin; Works only inside supported sites (Facebook, LinkedIn, X/Twitter, Quora) via the Chrome browser; AI-written comments can feel generic if prompts are not specific [Profile (Markdown)](https://openaitools.app/tool/replygpt.md) ## Frequently Asked Questions ### How do DeepSeek and ReplyGPT compare in monthly traffic?
