## 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

## InterviewPrep AI

InterviewPrep AI is a Chrome extension that turns a normal video call into an interview practice and support environment. Once installed, it layers an AI interview copilot onto Google Meet, Zoom, Microsoft Teams and comparable platforms, listening to the conversation and producing live transcription, structured notes and coaching as you go.

The extension leans on three ideas. First, real-time feedback: as you answer practice questions, the AI evaluates your responses and suggests improvements, closing the gap between rehearsal and readiness. Second, tailored simulations: it generates industry-specific questions so a software engineer and a sales candidate are not drilling the same generic list. Third, personal insight: it offers tips on delivery, structure and how to organise scattered thoughts into a coherent answer, plus a helper that captures coding questions from an active editor.

It is a third-party tool. The listing is published by an independent developer and marketed under the InterviewPrep AI name; it is not made by Google, Zoom or Microsoft, even though it runs inside those platforms. At review time the extension had around 3,000 users with a 4.6-star average from 21 ratings and a June 2026 update, indicating a maintained but still growing product. It is free to install with in-app purchases, and browser-based delivery means it is best suited to candidates interviewing on supported meeting platforms.

**Pricing & Plans:** InterviewPrep AI is free to install from the Chrome Web Store and offers in-app purchases for extra capability. Exact upgrade prices were not verifiable at review time — check the listing and the developer's site for current terms.

- **Real-time answer feedback:** The AI evaluates your spoken answers as you practise, giving constructive notes so you can tighten responses before the real interview.
- **Tailored practice simulations:** Generates industry- and role-specific questions to recreate realistic interview scenarios for technical, behavioural or situational rounds.
- **Live transcription and summaries:** Works alongside Google Meet, Zoom and Microsoft Teams, capturing the conversation and turning it into structured, reviewable notes.
- **Coding challenge support:** A one-click helper captures coding questions from an active editor so you can get support during technical practice.
- **Multi-device session access:** Share a session to follow the same practice run from a phone or tablet as well as your desktop.

**Strengths:** Runs inside the meeting platforms candidates already use, with no separate app to learn; Combines live transcription, real-time feedback and practice question generation in one extension; Lightweight install (about 2 MB) with a solid 4.6-star rating at review time; Multi-device session sharing is handy for reviewing practice on a phone or tablet

**Limitations:** Feedback quality depends on audio transcription accuracy, which can degrade with poor microphones or heavy accents; It is a browser extension, so it is tied to supported meeting platforms and Chrome rather than working everywhere; In-app purchases are required to unlock the full experience, and we could not verify exact pricing at review time
