## 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

## Protectstar

Protectstar has been building privacy software since 2004 and describes its philosophy as treating security as a human right: ad-free apps, no unnecessary data collection, and independent operation without the backing of a large corporate group. The product line covers two broad needs — keeping devices free of surveillance and malware, and making sure data that is deleted is genuinely unrecoverable.

On the protection side, Anti Spy detects stalkerware, hidden tracking apps and spy tools that run quietly in the background, and it holds dual certification from AV-TEST and DEKRA with a stated 99.87% detection rate. Antivirus AI applies on-device machine learning to catch new threats in real time on Android and Mac, and can also scan an iPhone when connected by USB to a Mac. Firewall AI, Camera Guard and Micro Guard round out the set by controlling network access and monitoring camera and microphone activity.

iShredder is the flagship erasure product. It overwrites storage according to recognised standards such as NIST SP 800-88 and DoD 5220.22-M and produces a certified erasure report, which is what makes it useful for GDPR compliance, device resale and IT asset disposal. Business and enterprise editions handle multiple devices and MDM integration, while iShredder Server covers servers and RAID arrays and a bootable edition serves government and defence requirements.

**Pricing & Plans:** Paid with free entry points. Several apps — Anti Spy, Antivirus AI, Firewall AI, Camera Guard, Micro Guard and the iShredder family — have free versions, with premium subscriptions advertised from around 1.6 to 2 US cents per day. Business, enterprise, server and defence editions are quoted individually. Purchases run through the vendor's own store as well as Google Play and the App Store.

- **Certified anti-spyware:** Anti Spy is presented as the first anti-spyware app with dual AV-TEST and DEKRA certification, with a stated 99.87% detection rate, plus dark web checks and camera/recording access monitoring.
- **On-device AI antivirus:** Antivirus AI combines a signature engine with on-device machine learning so new and unknown threats are caught in real time without sending your data to the cloud.
- **Certified secure erasure:** iShredder overwrites data using 23 algorithms based on standards from NIST SP 800-88 to DoD 5220.22-M ECE and issues a verifiable erasure report.
- **Hardware access controls:** Camera Guard and Micro Guard monitor and block camera and microphone access, while Firewall AI governs which apps can reach the network.
- **Business, server and defence editions:** Multi-device wiping, MDM integration, server and RAID array erasure and a bootable government-grade edition scale the same technology to organisations.

**Strengths:** Independent vendor with over two decades of history and a stated 8 million users; Anti Spy holds dual AV-TEST and DEKRA certification, unusual in the anti-spyware category; On-device AI processing keeps scan data local rather than in the cloud; iShredder's erasure reports are recognised by auditors for GDPR and asset disposal

**Limitations:** The product range is broad and overlapping, which makes choosing the right app confusing; Consumer subscriptions are billed per app rather than as one bundled suite; Business, server and defence pricing is only available on request
