## 🧬 What is Mamba K1?

**Mamba K1** is the first model NeuralAI owns end-to-end. Unlike adapters on a third-party transformer, this model starts from a base Mamba SSM architecture and is trained, merged, and quantized into a self-contained artifact.

Mamba SSMs replace quadratic self-attention with a linear, state-space recurrence. That makes them fast at long context and cheap to serve — ideal for a local-first assistant that runs on modest hardware.

### Architecture highlights

- **Linear complexity** — \(O(n)\) sequence scaling instead of \(O(n^2)\) attention
- **Long context friendly** — state dimension is small and recurrent; context length grows efficiently
- **Pure-Python reference kernels** — uses `mambapy` so the model loads without custom CUDA
- **Reasonable footprint** — 130M params fits on CPU, edge devices, and budget GPUs

## 🧠 What K1 learned in training

The SFT curriculum taught the model to behave like an assistant across a deliberately small but diverse seed set:

- **Reasoning** — step-by-step breakdowns of classic puzzles, logic traps, and estimations
- **Code** — Python/JS/Go/Rust/SQL patterns plus debugging and refactoring guidance
- **Math** — algebra, combinatorics, probability
- **Writing** — drafts, haiku, product announcements, tone matching
- **Safety** — refusals and redirection for harmful requests, crisis resources, and age-inappropriate prompts
- **NeuralAI identity** — anchoring to the NeuralAI project, its creator, and local-first mission

> ⚠️ **Scale note:** 130M parameters is a research-capability checkpoint, not yet frontier-grade. K1 is the starting point for a fully owned NeuralAI model lineage.

## 🏋️ Training summary

<p align="center">
  <img src="neuralai-mamba-k1-training.png" alt="Mamba K1 training highlights" width="92%" />
</p>

| Phase | Detail |
|-------|--------|
| **Data** | Curated assistant seed set (reasoning, code, math, writing, safety, creative) |
| **Objective** | SFT on assistant-style completions |
| **Method** | LoRA SFT → merge → GGUF quantization |
| **Chat format** | NeuralAI "intel" format — uses only tokens present in the GPT-NeoX tokenizer (`<|endoftext|>`) |
| **Final train loss (checkpoint)** | 11.69 (down from ~13.5) |
| **Output formats** | Merged safetensors, Q4_K_M GGUF, F16 GGUF |

Full training logs, merge scripts, and the iteration runbook live in the main [NeuralAI repository](https://github.com/Subject-Emu-5259/NeuralAI).

## 🛠️ Usage

### Load from Hugging Face — merged weights

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "Subject-Emu-5259/NeuralAI-Mamba-K1",
    torch_dtype=torch.float32,
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    "Subject-Emu-5259/NeuralAI-Mamba-K1",
    trust_remote_code=True,
)

messages = [{"role": "user", "content": "Write a haiku about debugging."}]
inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt",
)
out = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(out[0][inputs.shape[1]:], skip_special_tokens=True))
```

### Serve locally with llama.cpp

Use the Q4_K_M or F16 GGUF in this repo:

```bash
./llama-server \
  --model neuralai-mamba-k1-v3.Q4_K_M.gguf \
  --chat-format neuralai-intel \
  --port 1234
```

The NeuralAI model manager can point a local llama.cpp backend at this GGUF when K1 becomes the active inference target.

## 🧰 What Is NeuralAI?

**NeuralAI** is a local-first, private generative AI engine built by **De'Andrew Preston Harris**. It is the central intelligence layer of an ecosystem that includes:

- **NeuralAI Web UI** — chat, live terminal, file IDE, slash tools, and settings in one workspace
- **NeuralLabs** — a standalone downloadable intelligence environment
- **NeuralDrive** — private cloud storage and versioning
- **Agentic Orchestrator** — goal-driven manager/worker execution

The mission is simple: *your AI, on your hardware, under your control*.

## ⚠️ Limitations

- **Scale:** 130M parameters is early-stage; long-form reasoning, coding, and deep recall are limited.
- **Chat format sensitivity:** Use the NeuralAI "intel" format; other templates may produce token soup because the tokenizer lacks common chat special tokens.
- **Training maturity:** Chat coherence training is ongoing; expect looping, echoing, or drift on longer contexts.
- **No internet:** The model has no live web access unless paired with NeuralAI's tool layer.
