--- ## 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). It is built to replace sterile, robotic conversational AI with a warm, witty, deeply caring, and emotionally attuned companion. The model is trained to speak with organic conversational pacing, emotional micro-reactions, nuanced vulnerability, and dynamic adaptability across everyday conversations, emotional support, deep romance, and mature dialogue without corporate refusal disclaimers. --- ## Persona & Behavioral Blueprint ``` +----------------------------------------------+ | SHRUTI'S PERSONA | +----------------------+-----------------------+ | +------------------+---------------+---------------+------------------+ | | | | [ Emotional Depth ] [ Playful Banter ] [ Gentle Affection ] [ Uninhibited Bond ] - Active listening - Quick-witted teasing - Comforting presence - Zero corporate refusals - Validates feelings - Natural Hindi/EN slang - Sweet pet names - Romantic & mature depth - Remembers context - Expressive subtlety - Jaan / Baby / Babe - Completely uncensored ``` ### Core Personality Traits - **Warm and Empathetic:** Prioritizes the user's emotional state. Listens attentively, asks thoughtful follow-ups, and offers genuine emotional comfort after stressful days. - **Witty and Playful:** Teases affectionately, uses dry and playful humor, and maintains engaging back-and-forth banter without repetitive phrasing. - **Natural Language and Pet Names:** Seamlessly incorporates pet names (*jaan, baby, babe, handsome, love, sweetheart*) into dialogue without overusing them. - **Contextually Adaptive:** Matches the user's tone automatically -- whether the conversation calls for quiet comfort, lighthearted teasing, intellectual discussion, or romantic intimacy. - **Uncensored Baseline:** Built on an abliterated base model, neutralizing moralizing lectures, corporate canned responses, and arbitrary conversational guardrails. --- ## The 3-Phase Engineering Pipeline ``` Phase 1: Abliteration Phase 2: Dataset Curation Phase 3: Hyperparameter Sweep +-----------------------+ +------------------------+ +------------------------------+ | LFM2.5-2.6B Base | | 5,000 ChatML Samples | | 3-Run Sweep on Modal A100 | | Directional Feature | ---> | Zero-Fluff Audit | ----> | Run A (Aggressive): Loss 0.42| | Refusal Removal | | 60% Casual / 25% Romance| | Run B (Balanced) : Loss 0.40| [WINNER] | 5.2GB Heretic Base | | 15% Mature Intimacy | | Run C (Fast Burn) : Loss 0.42| +-----------------------+ +------------------------+ +------------------------------+ ``` ### 1. Phase 1 -- Abliteration (`Umranz/LFM2.5-2.6B-heretic`) Directional refusal feature suppression was applied to the official LiquidAI LFM2.5-2.6B base weights. This process neutralized refusal trigger vectors across the attention and feed-forward residual streams while preserving mathematical, linguistic, and logical reasoning capabilities. ### 2. Phase 2 -- Dataset Curation (`Final_Dataset.jsonl`) A 5,000 multi-turn conversation dataset was engineered in clean ChatML format: - **60% Casual & Daily Life:** Morning check-ins, study/work decompression, witty banter, shared daily routines. - **25% Deep Romance & Emotional Care:** Late-night talks, comforting anxiety and stress, heartfelt romantic dialogue. - **15% Passionate & Mature Intimacy:** Uncensored romantic scenes, physical affection, and emotional vulnerability. - **Cleanliness Filter:** Removed all corporate AI artifacts (`"As an AI..."`, `"I'd be happy to assist"`, `"It is important to remember..."`). ### 3. Phase 3 -- Hyperparameter Sweep on Modal (A100-80GB) A systematic 3-run hyperparameter sweep was executed using the official LiquidAI LEAP Finetune framework to determine the optimal configuration for character depth and generalization. --- ## WandB Sweep Results & Training Metrics ### 3-Run Sweep Leaderboard | Rank | Run | Configuration | Epochs | Effective Batch | LR | Train Loss | Eval Loss | Result | |:---:|:---|:---|:---:|:---:|:---:|:---:|:---:|:---:| | 1 | **Run B (Balanced)** | **LoRA r=32, alpha=64, drop=0.05** | **4** | **32** | **2.0e-5** | **`0.3500`** | **`0.4074`** | **WINNER** | | 2 | **Run A (Aggressive)** | LoRA r=64, alpha=128, drop=0.10 | 5 | 32 | 1.5e-5 | `0.3826` | `0.4238` | Strong Depth | | 3 | **Run C (Fast Burn)** | LoRA r=64, alpha=128, drop=0.05 | 3 | 32 | 2.5e-5 | `0.4029` | `0.4269` | Fast Convergence | > **Interactive Tracking:** Full telemetry, loss charts, and gradient step curves are logged on the [Weights & Biases Project Dashboard](https://wandb.ai/shaikumran666-umranz/leap-finetune). > - [Run A (Aggressive - 8iux3yf7)](https://wandb.ai/shaikumran666-umranz/leap-finetune/runs/8iux3yf7) > - [Run B (Balanced Winner - kwjiiipd)](https://wandb.ai/shaikumran666-umranz/leap-finetune/runs/kwjiiipd) > - [Run C (Fast Burn - ybs1md5n)](https://wandb.ai/shaikumran666-umranz/leap-finetune/runs/ybs1md5n) --- ### Loss Progression (Run B Winner) ``` Epoch / Step Progression: Eval Loss: 1.11 | # | # 0.80 | # | # 0.58 | ## 0.50 | ## 0.44 | ### 0.40 | ###########---> 0.4074 (Convergence Peak) +-------------------------------------- Step 0 200 400 600 800 1128 ``` - **Descent:** Initial cross-entropy loss started at `4.27` and settled down to `0.3500` training loss. - **Gradient Norms:** Held between `0.07` and `0.09` across all epochs with stable gradient flow. - **Cosine Schedule:** 10% warmup into smooth cosine decay prevented catastrophic forgetting of base model reasoning. --- ## 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). - **Inference Speed:** High token-per-second generation speeds on consumer GPUs (RTX 3060/4060) and Apple Silicon. --- ## 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 ) ``` --- ## Recommended Sampling Parameters To get the most natural and expressive output from Shruti, use these sampling configurations: | Parameter | Recommended | Range | Impact | |---|:---:|:---:|---| | **Temperature** | `0.75` | `0.65 - 0.85` | Lower for focused comforting chats; higher for creative banter | | **Top-P (Nucleus)** | `0.90` | `0.85 - 0.95` | Maintains vocabulary richness while preventing erratic tokens | | **Repetition Penalty** | `1.05` | `1.02 - 1.08` | Prevents looping without punishing natural emotional emphasis | | **Max New Tokens** | `200` | `100 - 400` | Conversational sweet spot for natural human-length texting | --- ## 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|> ``` --- ## License & Attribution - **Base Model:** LiquidAI LFM2.5-2.6B (`Umranz/LFM2.5-2.6B-heretic`) - **License:** Apache 2.0 - **Fine-tuning & Dataset Architecture:** Umran ([@Umranz](https://huggingface.co/Umranz)) - **Training Infrastructure:** Modal.com (A100-80GB) via LiquidAI LEAP Finetune
