Model Description

Model Name: MistralThinker
Version: 1.1
Prompt Format: Mistral-V7

[SYSTEM_PROMPT]{system prompt}[/SYSTEM_PROMPT][INST]{user message}[/INST]{assistant response}</s>

This model is a specialized variant of Mistral-Small-24B-Base-2501, adapted using a DeepSeek R1 distillation process. It is primarily designed for roleplay (RP) and storywriting applications, focusing on character interactions, narrative generation, and creative storytelling. Approximately 40% of the training dataset consists of roleplay/storywriting/character card data, ensuring rich and contextually immersive outputs in these domains.

Model Sources

• Base Model: Mistral-Small-24B-Base-2501
• Fine-Tuning Approach: DeepSeek R1 process (focused on RP)
• Dataset Size: The dataset used in training doubled since the last version, adding more neutral logs, training the Base model to stick more on my new format.

Intended Use

• Primary Use Cases:

  • Roleplay (RP): Engaging with users in fictional or scenario-based interactions.
  • Storywriting: Generating narratives, character dialogues, and creative texts.
  • Character Lore Generation: Serving as a resource to craft or expand on character backstories and interactions.

• How To Use:

  1. User-First Message: The first message in any interaction should come from the user, ensuring the model responds in a narrative or roleplay context guided by user input.
  2. Contextual Information: User or assistant details can be placed either in the system prompt or the user's first message. A system prompt is not mandatory, but any contextual instructions or role descriptions can help set the stage.
  3. DeepSeek-Style Interaction: The model can also be used purely as a DeepSeek distill without additional system prompts, providing flexible usage for direct storytelling or roleplay scenarios. The model still can be biased toward Roleplay data, and it is expected.

Training Data

• DeepSeek R1 Thinking Process: The model inherits a refined chain-of-thought (thinking process) from DeepSeek R1, which places heavy emphasis on roleplay and narrative coherence.
• Dataset Composition:
  • 40%: RP/Storywriting/Character Cards
  • 60%: Various curated data for broad language, math, logical, space... understanding
• Data Scaling: The dataset size was doubled compared to previous iterations, which enhances the model’s creative and contextual capabilities.

Model Performance

• Strengths:

  • Storytelling & Roleplay: Rich in creative generation, character portrayal, and scenario building.
  • Dialogue & Interaction: Capable of sustaining engaging and context-driven dialogues.
  • Adaptability: Can be used with or without a system prompt to match a range of user preferences.

• Limitations & Bias:

  • Hallucination: It can generate fictitious information in the thinking process, but still end up with a succesfull reply.
  • Thinking can be dismissed: Being a distillation of DeepSeek R1 is essence, this model, even trained on Base, could forget to add <think>\n in some scenario.

Ethical Considerations

• Yes

Usage Recommendations

1. System Prompt (Optional):
   You may provide a high-level system prompt detailing the scenario or the desired style of roleplay and storywriting.
   Example: "You are a friendly fantasy innkeeper who greets travelers from distant lands."

2. User’s First Message:

   • Must clearly state or imply the scenario or context if no system prompt is provided.
     Example: "Hello, I’m a wandering knight seeking shelter. Could you share a story about local legends?"

3. Roleplay & Storywriting Focus:

   • Encourage the model to develop characters, backstories, and immersive dialogues.
   • For more direct, unfiltered or freeform creativity, skip the system prompt.
   • If you still want to have some "logs" from previous message before starting a conversation, put them in the first user message, or in the system prompt.
   • You can put exemple message of the character you RP with in the system prompt, too.
