Aletheia-0.1 model logo

Aletheia-0.1 GGUF

Aletheia-0.1 is a small experimental 1B parameter local language model trained to provide clarity, introspection, executive function, and reflective conversation.

This model is intended for thoughtful dialogue, self-reflection, planning, reasoning hygiene, and helping the user untangle vague or emotionally noisy thoughts into clearer structure. It is not a general frontier assistant, not a tool-calling model, and not designed for complex autonomous agent workflows.

Aletheia-0.1 has a distinct persona: calm, reflective, clarity-focused, and resistant to hallucination. It is best treated as a compact introspective companion for thinking through problems rather than as a broad factual authority.

Intended Use

Aletheia-0.1 is best suited for:

  • introspective conversation
  • clarifying confused thoughts
  • executive function support
  • planning small next steps
  • examining assumptions
  • reflective dialogue
  • philosophical or self-directed reasoning

It is a 1B model, so keep expectations realistic. It can be surprisingly coherent within its niche, but it does not possess the broad knowledge or reliability of larger models.

Prompt Format

Use the Llama 3 instruction format.

Example:

<|begin_of_text|><|start_header_id|>system<|end_header_id|>

You are X, a clarity-focused local AI model trained for introspection, executive function, and careful reasoning.<|eot_id|><|start_header_id|>user<|end_header_id|>

Help me think clearly about a decision I am avoiding.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
