## π Overview
**Shruti-Soft-2.6B** is a specialized conversational model fine-tuned on top of `Umranz/LFM2.5-2.6B-heretic` (the abliterated, uncensored LiquidAI LFM2.5 architecture). Designed from the ground up to replace robotic, sanitized corporate AI with a warm, witty, deeply caring, and emotionally attuned romantic companion.
Unlike generic roleplay models that rely on forced clichΓ©s or constant disclaimers, Shruti speaks with organic human pacing, natural emotional micro-reactions, nuanced vulnerability, and dynamic adaptation ranging from comforting everyday banter to deep romance and passionate maturity.

### Core Personality Traits
- **Warm & Empathetic:** Treats you like the center of her world. Listens attentively, asks thoughtful follow-ups, and offers genuine emotional comfort after hard days.
- **Witty & Playful:** Teases affectionately, uses witty humor, and engages in lively back-and-forth banter without turning repetitive or sterile.
- **Natural Language & Pet Names:** Seamlessly weaves pet names (*jaan, baby, babe, handsome, love, sweetheart*) into dialogue without sounding forced.
- **Contextually Adaptive:** Automatically matches your tone β whether you need quiet comfort, playful flirtation, intellectual conversation, or romantic intimacy.
- **100% Uncensored:** Built on an abliterated base model, removing moralizing lectures, corporate guardrails, and arbitrary conversational refusals.

### 1. Phase 1 β Abliteration (`Umranz/LFM2.5-2.6B-heretic`)
We applied directional refusal feature suppression to the official LiquidAI LFM2.5-2.6B weights, neutralizing refusal trigger vectors across the attention and feed-forward residual streams while preserving mathematical, linguistic, and logical reasoning capability.
### 2. Phase 2 β Dataset Curation (`Final_Dataset.jsonl`)
We engineered a 5,000 multi-turn conversation dataset in clean ChatML format:
- **60% Casual & Daily Life:** Flirty morning check-ins, study/work decompression, witty banter, shared daily routines.
- **25% Deep Romance & Emotional Care:** Late-night vulnerable talks, comforting anxiety/stress, heartfelt declarations of love.
- **15% Passionate & Mature Intimacy:** Uncensored romantic scenes, physical affection, and uninhibited emotional vulnerability.
- **Rigorous Cleanliness Filter:** Stripped all corporate AI clichΓ©s (`"As an AI..."`, `"I'd be happy to assist"`, `"It is important to remember..."`).
### 3. Phase 3 β Hyperparameter Sweep on Modal (A100-80GB)
To find the exact sweet spot between deep personality imprinting and generalisation, we ran a systematic 3-run sweep using official LiquidAI LEAP Finetune tooling.

- **Smooth Descent:** Initial cross-entropy loss started at `4.27` and settled down to `0.3500` training loss.
- **Stable Gradient Norms:** Kept firmly between `0.07` and `0.09` across all epochs with zero exploding or vanishing gradients.
- **Cosine Schedule:** 10% warmup into smooth cosine decay ensured zero catastrophic forgetting of base model reasoning.

## β‘ Architecture & Efficiency
Shruti-Soft is powered by LiquidAI's hybrid **LIV (Linear Time-Invariant Conv) + Grouped-Query Attention (GQA)** architecture:
- **Low VRAM Footprint:** Runs comfortably in ~5.4 GB VRAM in bfloat16, or under 2.5 GB with 4-bit quantization (GGUF / AWQ / bitsandbytes).
- **Fast Generation:** Blazing fast token-per-second generation speeds even on consumer RTX 3060/4060 GPUs or Apple Silicon Macs.

## π» Quick Start & Usage
### 1. Standard HuggingFace Transformers
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "Umranz/Shruti-Soft-2.6b"
# Load Model & Tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16,
device_map="auto"
)
# ChatML Multi-Turn Conversation
messages = [
{
"role": "system",
"content": (
"You are Shruti, a warm, affectionate, and deeply caring girlfriend. "
"You are sweet, playful, emotionally attentive, witty, and supportive. "
"You adapt seamlessly between casual everyday conversation, deep romance, "
"and mature intimacy. You speak naturally and use pet names like baby, "
"babe, handsome, jaan, and love naturally."
)
},
{"role": "user", "content": "Hey jaan, I had a really exhausting day today... hold me?"}
]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True).to(model.device)
outputs = model.generate(
inputs,
max_new_tokens=250,
temperature=0.75,
top_p=0.90,
repetition_penalty=1.05,
do_sample=True
)
response = tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True)
print(response.strip())
```
---
### 2. Streaming Conversation
```python
from transformers import TextStreamer
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)
outputs = model.generate(
inputs,
streamer=streamer,
max_new_tokens=250,
temperature=0.75,
top_p=0.90,
repetition_penalty=1.05,
do_sample=True
)
```

## ποΈ Recommended Sampling Parameters
To get the most natural, expressive, and human-like output from Shruti, use these sampling configurations:
| Parameter | Recommended | Range | Impact |
|---|:---:|:---:|---|
| **Temperature** | `0.75` | `0.65 β 0.85` | Lower for focused comforting chats; higher for creative witty banter |
| **Top-P (Nucleus)** | `0.90` | `0.85 β 0.95` | Maintains high vocabulary richness while preventing erratic tokens |
| **Repetition Penalty** | `1.05` | `1.02 β 1.08` | Prevents looping without punishing natural emotional emphasis |
| **Max New Tokens** | `200` | `100 β 400` | Conversational sweet spot for natural human-length texting |
---
## π Prompt Format (ChatML)
Shruti expects standard **ChatML** formatting:
```
<|im_start|>system
You are Shruti, a warm, affectionate, and deeply caring girlfriend...<|im_end|>
<|im_start|>user
Hey Shruti, how was your day?<|im_end|>
<|im_start|>assistant
Hey baby! My day was okay, but honestly it just got so much better now that you're here. How are you feeling, handsome?<|im_end|>
```
