## 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

## WebFill

WebFill is an AI browser extension built around repetitive web work: filling forms, completing surveys, entering data, answering multiple-choice questions and drafting emails. It uses advanced AI models to read what is on a page and act on it, and it can also work from a PDF, pasted text or the intelligent instruction setup you save for each website.

A distinguishing feature is WebFill Vision. Designed for students and professionals, it lets you capture any part of your screen and get instant answers — the company describes it as operating within your browser for tasks such as MCQs and online assessments. The extension also includes a chatbot for general questions and email assistance that can generate or respond to messages from your inbox.

Pricing is tiered. The Free plan covers 1K words per month, basic support, basic AI models, automated form filling and 20 Vision uses per month. The Standard plan at $7.99/month raises that to 100K words and 400 Vision uses with priority support and access to the most powerful models, while the Premium plan at $19.99/month offers 250K words, 1,000 Vision uses and enterprise-level data security. WebFill reports over 1K active users, 8K+ customers and millions of Vision launches and chats, and it also runs an affiliate program.

**Pricing & Plans:** Freemium. Free plan: 1K words/month, basic models, 20 Vision uses. Standard: $7.99/mo (100K words, 400 Vision uses). Premium: $19.99/mo (250K words, 1,000 Vision uses, enterprise-level data security). Annual billing saves 20%.

- **Automatic form filling:** WebFill detects fields on a page and completes forms, surveys and data-entry screens automatically, learning per-site instructions over time.
- **Screenshot analysis with Vision:** WebFill Vision captures any part of your screen and returns answers, aimed at multiple-choice questions, online assessments and on-screen content.
- **AI email generation:** Generate or reply to emails straight from your inbox by pressing the WebFill button and letting the AI draft the response.
- **Task and data-entry automation:** Upload a PDF or paste text and let WebFill handle repetitive data entry, MCQ solving and survey completion with saved instructions per website.
- **Tiered plans and models:** Choose from free, Standard and Premium plans with increasing word budgets, Vision usage and access to more powerful AI models.

**Strengths:** Automates genuinely tedious work like forms, surveys and data entry; WebFill Vision reads on-screen content for quick answers; Saves per-website instructions so repeated tasks get faster over time; Handles email drafting and replies from directly inside your inbox

**Limitations:** Vision features aimed at exam and MCQ answering sit in a gray area with many schools' and employers' policies; Word and Vision usage are capped by plan, so heavy users may hit limits quickly; The free tier is limited to 1K words per month with basic models and 20 Vision uses
