AI Options

Choose AI Option

CreatureChat™ requires an AI / LLM (large language model) to generate text (characters and chat).

Free & Local: Use open-source and free-to-use LLMs without any API fees. [Difficulty: Hard]
Bring Your Own Key: Use your own API key from providers like OpenAI or Groq. [Difficulty: Medium]
Token Shop: Supports CreatureChat™ by purchasing tokens from the developers. [Difficulty: Easy]

1. Free & Local

CreatureChat™ fully supports free and open-source LLMs. To get started:

An HTTP endpoint compatible with the OpenAI Chat Completion JSON syntax is required. We highly recommend using:
- Ollama & LiteLLM as your HTTP proxy.
- LiteLLM Features:
  - Supports over 100+ LLMs (e.g., Anthropic, VertexAI, HuggingFace, Google Gemini, and Ollama).
  - Proxies them through a local HTTP endpoint compatible with CreatureChat™.
  - Note: Running a local LLM on your computer requires a powerful GPU.
Set the local HTTP endpoint in-game:
- /creaturechat url set "http://ENTER-YOUR-HTTP-ENDPOINT-FROM-LITE-LLM"
- /creaturechat model set ENTER-MODEL-NAME
- /creaturechat timeout set 360
Additional help can be found in the #locall-llm-info channel on our Discord.

2. Bring Your Own Key

For those already using a third-party API (e.g., OpenAI, Groq):

Integrate your own API key for seamless connectivity.
Costs depend on the provider’s usage-based pricing model.
By default, CreatureChat uses the OpenAI endpoint and gpt-3.5-turbo model, known for its balance of low cost and fast performance.
Be aware that OpenAI’s developer API does not include free usage. Please review the OpenAI pricing for detailed information.
To create an OpenAI API key, visit https://platform.openai.com/api-keys, and use the + Create new secret key button.
Set the API key & model in-game:
- /creaturechat key set <YOUR-SECRET-KEY-HERE>
- /creaturechat model set gpt-3.5-turbo

3. Token Shop

Supports CreatureChat by purchasing tokens from the developers:

Easy setup with simple token packs, created for CreatureChat users.
More info is available in the #token-shop channel on our Discord.
Set the token-shop API key in-game:
- /creaturechat key set <YOUR-SECRET-KEY-HERE>

Frequently Asked Questions

CreatureChat™ server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.7). You can switch loaders with one click in the panel.

Is CreatureChat™ compatible with fabric and forge and neoforge?

CreatureChat™ officially supports fabric, forge, neoforge for Minecraft 1.21.7, 1.21.6, 1.21.5. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with CreatureChat™ – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CreatureChat™ consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
