## 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

## Ghostly Chat

Ghostly Chat, at ghostly.chat, is a self-serve chatbot builder aimed at people who want an assistant on their website without writing code or paying per message. Its defining choice is a bring-your-own-key model: you supply your own OpenAI API key for GPT-3.5, GPT-4 or GPT-4o, and Ghostly charges only for the bot infrastructure, so you stay in control of how much AI you consume. Setup is designed to take about five minutes.

Training and customisation are the core of the product. You upload the material your bot should know — PDF, text and Markdown files, plus URLs for Ghostly to scrape — and you can always go back and adjust which files the bot is trained on. To shape behaviour you edit the system prompt, set predefined responses, and configure a welcome message. Appearance is just as flexible: pick a colour theme, set your primary colours, add your logo and switch between dark and light themes so the widget blends into your site.

Once configured, you embed the widget on your website and can offer it in multiple languages with easy translations. The pricing structure is deliberately not per-message: a free plan covers one chatbot, a bring-your-own-key setup, 30,000 characters of knowledge and website links, while paid Basic and Pro tiers raise the chatbot count, character allowance and website-link limits and remove the 'Powered by Ghostly' badge. All plans use your own OpenAI key.

**Pricing & Plans:** Ghostly Chat uses a freemium model built around your own OpenAI API key, so you pay only for bot infrastructure. There is a Free plan ($0, 1 chatbot, 30,000 characters, website links, GPT-3.5/GPT-4/GPT-4o), and paid Basic and Pro tiers that increase chatbots, character limits and website links and remove the Ghostly branding. Check the pricing page for current figures.

- **Bring your own API key:** Connect your own OpenAI key for GPT-3.5, GPT-4 or GPT-4o so you control AI usage costs — Ghostly only charges for the bot infrastructure.
- **Train on your own data:** Upload PDF, text and Markdown files and add website URLs; you can revisit and change the files your bot is trained on at any time.
- **Customise behaviour:** Shape exactly how your bot responds with a configurable system prompt, predefined responses and welcome messages.
- **Brand the widget:** Adjust the colour theme, logo and primary colours, and choose dark or light mode so the chatbot fits your website.
- **Easy embed and translations:** Embed the chatbot on your site with simple configuration and offer it to visitors in multiple languages.

**Strengths:** No-code setup that takes about five minutes; Bring-your-own-key pricing avoids unpredictable per-message charges; Train on PDFs, text, Markdown and website URLs, and adjust later; Full control over system prompt, appearance, themes and translations

**Limitations:** Requires your own OpenAI API key, so you manage an OpenAI account separately; Usage costs depend on OpenAI's pricing rather than a flat all-in fee; Knowledge limits on lower tiers are measured in characters and can run out quickly
