Cloud LLM Setup Guide

RimSynapse Core provides seamless integrations with three of the most powerful frontier model providers: OpenAI, Google Gemini, and Anthropic Claude. It also includes a completely free, built-in image provider (Pollinations.ai) that requires no setup whatsoever!

This guide will walk you through how to generate the API keys necessary to enable the frontier text and vision models.

🎨 Free Image Generation (No Setup Required!)

Before diving into API keys, you should know that RimSynapse Core already has a fully integrated, open, and free image generation provider: Pollinations.ai.

  • Cost: 100% Free
  • API Key: None required!
  • Setup: None! It is hardwired into the Core and is ready to generate pictures for your Factions and World News events the moment you install the mod.

1. OpenAI (GPT-4o, GPT-4-Turbo)

OpenAI provides industry-leading reasoning, vision, and text generation. It operates on a Pay-As-You-Go model. You must load your account with at least $5.00 in credits to use the API.

OpenAI API Keys Dashboard

Steps to Generate an API Key:

  1. Navigate to the OpenAI API Keys Dashboard.
  2. Log in with your OpenAI account.
  3. On the left-hand sidebar, click API Keys.
  4. Click the black Create new secret key button in the center.

2. Google Gemini (Gemini 1.5 Pro)

Google Gemini offers a massive context window and lightning-fast vision capabilities. Google currently offers a generous Free Tier for Gemini, allowing you to use it without paying a dime (subject to rate limits)!

Google AI Studio Dashboard

Steps to Generate an API Key:

  1. Navigate to Google AI Studio.
  2. Log in with your Google account.
  3. Click the Get API key button on the left sidebar.
  4. Click the white Create API key button in the top right.

Copy API Key

  2. Paste this key into the Google Gemini Key field in the RimSynapse Provider Settings window.

3. Anthropic Claude (Claude 3.5 Sonnet)

Anthropic's Claude 3.5 Sonnet is arguably the best overall model for RimSynapse right now, balancing high-speed responses with top-tier intelligence. Anthropic uses a Pay-As-You-Go model, meaning you will need to add a small amount of billing credits to use the API.

Steps to Generate an API Key:

  1. Navigate to the Anthropic API Console.
  2. Log in with your email or Google account.
  3. If this is your first time, you may need to verify a phone number and add a minimum balance of $5 to your billing account.
  4. Click the black Create key button in the top right.
  5. Name your key something recognizable like "RimSynapse" and click Create.

Copy Anthropic Key

  1. Copy the generated API key immediately (it starts with sk-ant-).
  2. Paste this key into the Anthropic Claude Key field in the RimSynapse Provider Settings window.

Security Reminder

Never share your API keys. If you accidentally paste your API key in a public Discord server or GitHub issue, the provider will automatically detect it, revoke the key, and you will have to generate a new one.

4. ElevenLabs (TTS Audio)

ElevenLabs provides the gold standard in AI speech synthesis for immersive roleplay. They offer an incredible Free tier (10,000 characters per month) if you create an account, making it perfect for trying out high-quality game voices.

ElevenLabs Signup

Steps to Generate an API Key:

  1. Navigate to ElevenLabs.
  2. Create an account or log in.
  3. If presented with a subscription pricing page during signup, you can simply click Skip at the bottom to remain on the free tier. ElevenLabs Skip Subscription
