## 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

## Interview Solver

Interview Solver targets the practical mechanics of live technical interviews. The desktop application can screengrab any window and send the captured problem to an AI model that returns a working solution, along with an explanation of the approach and complexity notes. Voice transcription captures both your microphone and the interviewer's audio, so spoken questions in system design or behavioral rounds also produce answers.

A strong emphasis is placed on staying invisible during the interview. The app is designed to be hidden from Zoom screen sharing and browser-based recording, uses global hotkeys that don't require alt-tabbing, and is reported as invisible in the macOS Activity Monitor. A Companion mode pairs the desktop app with a phone, letting you trigger screenshots, voice capture and prompts remotely, which is useful when an assessment tool logs keystrokes on the interview laptop.

Setup starts with a free trial that needs no credit card, covering 10 minutes and 10 AI answers. Beyond that, subscriptions are simple: a monthly plan for a single interview loop or a three-month plan covering a full job search cycle. The product also ships free side utilities such as an ATS resume checker, a STAR method builder and a salary lookup.

**Pricing & Plans:** Free trial with no credit card: 10 minutes and 10 answers, everything included. Paid plans are $59 per month for one interview loop, or $149 every three months (about $50/month) for a full interview cycle.

- **Invisible during screen sharing:** The desktop app is designed to remain hidden from Zoom and browser-based screen recording, with moveable overlays and no visible taskbar presence.
- **Screengrab solving:** Capture any window containing a coding problem and receive a complete solution with syntax highlighting, approach notes and complexity analysis.
- **Live voice transcription:** Transcribes both your voice and the interviewer's audio so spoken system design and behavioral questions can be answered in the moment.
- **Companion mode and mobile:** Pair the desktop app with a phone for remote screenshots, prompts and answers, or use the browser-based mobile mode with no installation.
- **Undetectable global hotkeys:** Trigger answers without alt-tabbing or moving the mouse, so your on-screen behavior stays consistent during the call.

**Strengths:** Purpose-built for coding interviews with full LeetCode-style coverage and syntax highlighting; Desktop app design avoids the screen-sharing blindness of browser-extension copilots; Mobile mode works without installing anything, just a phone browser; Free trial requires no credit card and includes the full feature set

**Limitations:** Using an AI copilot in a proctored interview may violate employer or assessment-platform rules; The monthly single-loop plan is costly if a job search spans several months; It requires the desktop app for screenshot and hotkey features, so mobile alone is more limited
