## CAVEDUCK

CAVEDUCK is a character-chat platform built around the idea that the user, not a fixed protagonist, drives the story. You pick from a large catalogue of AI companions or design your own, then hold open-ended conversations that unfold as roleplay, romance, fantasy adventure, or whatever premise the character carries.

Creating a character means defining more than a name and an avatar. You set personality traits, background, a scenario that frames the first meeting, and a greeting message that shapes the tone of the conversation. CAVEDUCK also offers World and Scenario frameworks so characters can share a common setting, which makes multi-character storytelling and consistent worldbuilding possible.

Discovery is a big part of the experience. The home feed surfaces featured, recent, trending, and popular characters alongside curated picks from official creators and rising talent, and tags help you find a specific vibe quickly. A Store provides premium characters, subscriptions, and credit options on top of the free experience. CAVEDUCK hosts mature roleplay categories with age-gating and published terms, and operates from a registered US address with support and policy pages for privacy, refunds, and DMCA complaints.

**Pricing & Plans:** CAVEDUCK follows a freemium model with a free trial. Core chat is available without payment, while a Store offers premium characters, subscriptions, and credit purchases for additional features and content.

- **Custom character creation:** Build companions with defined personality, backstory, scenario, and opening message so chats follow your premise.
- **Large character library:** Browse featured, trending, popular, and recent characters, plus curated selections from official and rising creators.
- **Worlds and scenarios:** Go beyond single characters with World and Scenario frameworks that set shared settings and premises for roleplay.
- **Character store and premium options:** A Store with premium characters and credit-based options sits alongside free chat, so you can explore before spending.
- **Discovery and community features:** Tag-based discovery, activity feeds, and mature content categories with age restrictions and published policies.

**Strengths:** Deep character creation with personality, backstory, scenario, and greeting controls; Large, well-organised library with featured, trending, and curated character feeds; World and Scenario tools enable consistent, multi-character storytelling; Free trial and freemium access let you explore before paying

## 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
