Overview

ia-espirita/riv-ai-v2 is an 8 billion parameter instruction-tuned model, developed by IA.Espirita, specifically designed for the Spiritist Doctrine. It is fine-tuned using QLoRA on the Llama 3.1 8B Instruct base model. This version significantly expands upon its predecessor (v1) by incorporating a dataset four times larger, comprising 4,896 question/answer pairs extracted from the complete works of Allan Kardec, including the five canonical works, complementary texts, and the Revista Espírita (1858–1869).

Key Capabilities

  • Doctrinal Precision: Provides answers grounded in Allan Kardec's integral work.
  • Source Citation: Automatically references the book, question, and/or chapter for each response.
  • Didactic Tone: Explains complex Spiritist concepts in an accessible and friendly manner.
  • Modern Analogies: Translates Spiritist concepts into contemporary language when appropriate.
  • Brazilian Portuguese: Natively trained and optimized for PT-BR.

Good For

  • Study and Research: Ideal for individuals studying Spiritism who require accurate, sourced information.
  • Dissemination: Useful for creating educational content or tools about the Spiritist Doctrine.
  • Offline Deployment: Available in GGUF format for local inference with tools like Ollama, LM Studio, and llama.cpp.
  • Developer Integration: Can be integrated into Python applications using the Transformers library or deployed as an OpenAI-compatible server with vLLM.
