🍌 BananaMind V1

A small, local, and honestly not very good 125M parameter language model — but it runs fast, fits anywhere, and it’s yours.

⚠️ Fair warning: This is a personal project model. It will hallucinate, forget things after 512 tokens, and occasionally say something completely unhinged. You have been warned.

Quick Start

ollama run banaxitech/bananamind-v1

That’s it. No GPU required.

What Is This?

BananaMind V1 is a tiny conversational model fine-tuned on the OpenAssistant oasst1 dataset. It uses the ChatML prompt format and is designed for local, CPU-friendly inference.

Modelfile

If you’re building on top of this model or tweaking settings, here’s the full Modelfile:

FROM ./BananaMind-V1.gguf

TEMPLATE """<|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
{{ .Prompt }}<|im_end|>
<|im_start|>assistant
"""

PARAMETER top_p 0.9
PARAMETER stop <|im_end|>
PARAMETER temperature 0.8
PARAMETER top_k 50

The newlines inside the TEMPLATE block must be real newlines, and stop must be set without quotes.

Usage Tips

• Keep prompts short and direct — 512 tokens goes fast
• Works best for simple Q&A and casual chat
• Don’t trust it for facts, math, or anything important
• Higher temperature = more creative (and more unhinged)

Limitations

• Forgets context quickly (512 token window)
• Makes things up with confidence
• Struggles with multi-step reasoning
• Not suitable for production use
