✅ Compatible with offline environments
✅ Proven for secure deployments

---

MCP (Model Context Protocol) Integration

Vayne-V1 supports MCP-based agent tooling, making it easy to integrate tool-use AI.

Works seamlessly with:

• Claude MCP-compatible agent systems
• Local agent runtimes
• JSON structured execution

---

RAG Compatibility

Designed for hybrid reasoning + retrieval.

✅ Works with FAISS, Chroma, Elasticsearch
✅ Handles long-context document QA
✅ Ideal for enterprise knowledge bases

---

Quick Start

pip install transformers peft accelerate bitsandbytes

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "PoSTMEDIA/Vayne-V1"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

prompt = "Explain the benefits of private AI for enterprise security."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_length=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

---

Use Cases

✅ Internal enterprise AI assistant
✅ Private AI document analysis
✅ Business writing (reports, proposals, strategy)
✅ AI automation agents
✅ Secure RAG search systems

---

Safety & Limitations

• Not intended for medical, legal, or financial decision-making
• May occasionally generate hallucinations
• Use human validation for critical outputs
• Recommended: enable output guardrails for production
