## 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

## Perplexity Comet

Comet is a standalone web browser built by Perplexity around an AI assistant. Instead of treating AI as a separate site you visit, Comet embeds it in the browsing experience, so the assistant already knows which page you are looking at and can act on it. You can ask about an article you are reading, have a long page summarized, or hand off a task and let the assistant carry it out.

The browser is pitched as a personal assistant that handles more than chat. It can research a topic, draft an email reply that reflects your schedule, build a small website, put together a study plan, compare how different outlets cover a story, or help with shopping. Because it lives in the browser, these tasks run against the real web rather than a sandboxed chat window.

Comet is available for Mac, Windows, iOS, and Android, and can be set as your default browser. It sits within Perplexity's freemium model: you can start free and unlock more advanced AI capability through paid subscription tiers. Privacy and safety controls are managed in the browser settings, and Perplexity publishes guidance on how browsing data is handled.

**Pricing & Plans:** Freemium with paid options. Comet itself is free to download across Mac, Windows, iOS, and Android. Advanced AI capabilities and higher usage limits are tied to Perplexity's paid subscription tiers, which are billed separately.

- **AI that understands the page:** The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
- **Agentic task execution:** Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
- **Cross-platform availability:** Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
- **Perplexity search built in:** Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.
- **Default browser and privacy controls:** Set Comet as your default browser and manage privacy and safety settings as you browse.

**Strengths:** The assistant sees the page you are on, so answers are grounded in your actual context; Handles real tasks like drafting email, building simple artifacts, and research, not just Q&A; Available across desktop and mobile platforms; Brings Perplexity's answer engine into the browser by default

**Limitations:** Requires switching from your current browser to get the full experience; Best features depend on a Perplexity account and subscription tier; Agentic automation is powerful but should be supervised on sensitive tasks
