## 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

## InterviewFox AI

InterviewFox AI is built around a simple premise: during a live interview you should not have to split attention between talking and operating software. The assistant listens to the interviewer's audio, recognizes the question, reads the intent, and produces a structured answer drawn from your own resume and uploaded background material, so the response sounds like you rather than a generic template. A dedicated coding mode extends this to algorithms, dry runs, system design, and implementation questions, writing code and explaining the approach in a form you can narrate out loud.

Its most distinctive feature is dual-device mode. Rather than drawing an invisible overlay on the same display you screen-share, InterviewFox pairs your computer with your phone so the answers appear on the second device while your interview screen stays clean. That design decision is aimed at candidates who worry that hidden desktop overlays are easy to detect. Around the live assistant sits a preparation layer that runs over WhatsApp or SMS: a chat agent that optimizes resumes, drafts cover letters, runs mock interviews, and gives strategic feedback, then feeds that context back into live sessions and post-interview reviews.

The product works across common meeting and assessment platforms including Zoom, Google Meet, Microsoft Teams, LeetCode, HackerRank, and CodeSignal, and it advertises support for 35+ interview languages. Pricing is a straightforward candidate subscription rather than an enterprise contract. This is a third-party, independent tool: it is not built by or endorsed by any video-conferencing provider, coding assessment vendor, or employer, and using assistance in a proctored or honesty-bound interview is the user's own responsibility.

**Pricing & Plans:** Freemium. A free tier lets you start and evaluate the assistant. Paid plans are billed as a single recurring charge: approximately $49/month billed monthly, $39/month billed quarterly, or $29/month billed annually. Higher-priced tiers unlock broader model access; all paid tiers include dual-device mode, unlimited interview sessions, screenshot analysis, and context uploads. Credit packs are available after login.

- **Real-time answer generation:** Recognizes live interview questions, interprets the intent behind them, and produces professional, resume-tailored answers in milliseconds.
- **Dual-device mode:** Pairs your computer and phone so AI answers render on the second screen and never appear on the display you are sharing with an interviewer.
- **AI coding interview assistant:** Generates code, walks through the reasoning, and helps with dry runs, algorithms, and system design questions in technical interviews.
- **WhatsApp and SMS prep agent:** A chat-based coach that optimizes resumes, writes cover letters, runs mock interviews, and reviews performance before and after interviews.
- **Broad platform and language support:** Works alongside Zoom, Google Meet, Microsoft Teams, LeetCode, HackerRank, CodeSignal and more, with assistance available in 35+ interview languages.

**Strengths:** Dual-device separation keeps AI guidance off the shared interview screen, which is a real differentiator against invisible-overlay tools.; Answers are grounded in your uploaded resume and knowledge base rather than being generic.; Covers the full loop: preparation, live answers, coding rounds, and post-interview review.; Prep agent works over WhatsApp and SMS, so practice fits into normal messaging habits.

**Limitations:** Subscription cost is meaningful for candidates interviewing only occasionally.; Usage in proctored or honesty-bound interviews may breach employer or platform rules and is the user's responsibility.; Answer quality depends heavily on the quality of the resume and context you upload.
