# MOTHER CORE V3

Sovereign UK reasoning + **agentic** model by **MediaStream AI (MSAI)**. V3 is a
~6.9B custom transformer trained on a 2.4M-record curriculum spanning reasoning,
multi-step tool-calling, RAG, document/code generation, and safety — served via
`trust_remote_code`.

## Eval (105-task agentic benchmark)

| Version | Score | Degeneration |
|---|---|---|
| V2 (chunk 0600) | 51 / 105 (49%) | — |
| **V3 (chunk 1550)** | **81 / 105 (77%)** | low |

+30 tasks over V2; clean tool-call termination. Training ongoing toward 80%+.

## Architecture

Custom `MotherCoreModel` (requires `trust_remote_code=True`):

## Inference

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
R = "MediaStreamAI/MOTHER_CORE_V3"
tok = AutoTokenizer.from_pretrained(R, trust_remote_code=True)
m = AutoModelForCausalLM.from_pretrained(R, trust_remote_code=True,
                                         torch_dtype=torch.bfloat16, device_map="auto").eval()

def ask(q, n=256):
    ids = tok(f"Question:\n\n{q}\n\nAnswer:", return_tensors="pt").input_ids.to(m.device)
    out = m.generate(ids, max_new_tokens=n, do_sample=False,
                     repetition_penalty=1.2, no_repeat_ngram_size=4, pad_token_id=tok.pad_token_id)
    return tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True).strip()

print(ask("What is the capital of Scotland?"))   # Edinburgh is the capital of Scotland.
```

**Agentic loop:** the model emits a single `TOOL_CALL tool(args)`; your runtime runs
it and feeds the result back as a separate `tool` turn (`TOOL_RESULT {...}`); the
model then continues. Use greedy decoding; keep `repetition_penalty≈1.2`.

## Limitations & safety
- Some file-format routing still imperfect; arithmetic should be checked.
- Non-weapon posture: observation + human-in-the-loop only; refuses forgery,
  fraud, phishing, and destructive actions.
- Knowledge fixed at training time — verify before acting.
