## 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

## Leetcode Wizard

Leetcode Wizard targets a specific, uncomfortable moment: the technical interview where a familiar-feeling problem turns out to be one you have never seen. The desktop app runs invisibly on top of the interview environment. After you select your programming language and input source, the model inspects the problem and returns a ranked list of candidate algorithms ordered from worst to best time complexity, followed by code in the chosen language along with edge-case tests and a complexity analysis.

Control is deliberately hands-off. Global hotkeys operate at a privileged level so they remain invisible to browsers and other software, and the window is designed not to appear in screenshots or screen-sharing captures. For proctored sessions, a companion web view can mirror all output to a phone, tablet or second laptop, letting the desktop app stay hidden while the candidate reads from another device. All model output is passed through a humanizer to reduce AI-detection signals, and the vendor reports parity testing against hundreds of real interviews, including FAANG loops, plus more than 250 mock interviews.

The product covers any problem rather than a fixed database, including questions that do not exist publicly, and supports input from platforms such as LeetCode, HackerRank, CodeSignal and Codility on the paid tier. Pricing is a single Pro subscription at €49 per month with free updates; a free trial is available, though trial input is limited to LeetCode.com. Because the tool is designed to be used undetected in assessments, candidates should weigh employer policies and platform terms before relying on it.

**Pricing & Plans:** Paid subscription. A Pro plan is listed at €49 per month and includes unlimited uses, any input source, the secondary-device web view, priority AI responses and premium support, with future updates included. A free trial exists but restricts input to LeetCode.com.

- **Algorithm suggestions in seconds:** The model inspects the problem and returns several viable algorithms sorted from worst to best time complexity, including for problems that are not published anywhere.
- **Code, tests and complexity analysis:** Pick an algorithm and receive idiomatic code for your chosen language, edge-case tests and a written complexity analysis within seconds.
- **Stealth desktop overlay:** Undetectable global hotkeys run at a privileged level, and the window is designed to stay invisible in screenshots and screen-sharing software.
- **Secondary-device web view:** Mirror every output to a phone, tablet or second laptop so you never need to open anything on the machine being proctored.
- **Humanized output:** All responses pass through a humanizer layer intended to strip patterns that AI-detection tools look for in generated text.

**Strengths:** Returns algorithms, code, edge-case tests and complexity notes in one pass; Undetectable hotkeys and a separate web view give genuine operational flexibility; Not limited to a fixed problem database, so fresh or unpublished questions are still handled; Trial available, and the Pro plan includes all future updates

**Limitations:** Explicitly positioned as interview cheating, which conflicts with most employer and platform policies; Uses a subscription rather than a one-time purchase, at €49 per month; The free trial only accepts input from LeetCode.com, so other platforms need Pro
