## Deep Search

Deep Search replaces the tedious ritual of opening a dozen browser tabs whenever you need to understand a person. Instead of jumping between LinkedIn, a Google results page, a GitHub account and a company team page, you start with a single name and optionally add context such as employer, city or job title. The tool then proposes candidate matches so you can confirm you are looking at the right individual, especially with common names.

Once a match is confirmed, Deep Search compiles a structured profile: current and previous roles, companies, most likely city and region, education and alumni mentions, plus news articles, podcast appearances, talks and other web mentions. Everything is condensed into a short AI summary with inline links, so each assertion can be traced back to the public page it came from. A follow-up chat lets you ask targeted questions about a person's projects, background or public statements without starting the research over.

Deep Search presents itself as a tool for recruiters sourcing passive candidates, founders preparing for investor and partner conversations, analysts mapping a market, and journalists doing pre-interview research. Lookups are private — the people you search are not notified — and the site repeatedly notes that it is for research only, not for regulated screening decisions such as employment, credit, housing or insurance.

**Pricing & Plans:** Paid subscription. The site advertises plans starting at $7.99 per week, with higher tiers available; exact limits and feature splits should be confirmed on the vendor's own pricing page before purchase.

- **Name-based search with candidate matching:** Enter a name, add optional context like company or location, and pick the right person from a list of matching profiles before generating anything.
- **AI-enriched structured profiles:** Roles, companies, career arcs, likely location, education and web mentions are assembled into one readable dossier rather than scattered across sites.
- **Fully sourced claims:** Each statement in the summary is linked to the public page it came from, so you can verify facts instead of trusting an opaque model output.
- **Follow-up research chat:** Ask clarifying questions about a person's projects, roles or public statements and get answers grounded in the collected sources.
- **Private lookups:** Searches do not notify the subject, and the product is positioned as open-web research rather than contact or surveillance data mining.

**Strengths:** Consolidates a multi-tab manual research process into a single search and summary; Sources are linked, which makes verification possible instead of taking an AI summary on faith; Candidate disambiguation helps with common names and false matches; Lookups stay private and the subject is never notified

**Limitations:** Not a background check service and not FCRA-compliant, so it cannot be used for regulated screening decisions; Quality depends entirely on how much public web presence a person has — thin profiles yield thin results; Subscription-only with weekly pricing, and no permanent free tier advertised on the homepage

## 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
