## 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

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
