# Enterprise Generative AI Development Company

> Custom LLM fine-tuning (LoRA/QLoRA), advanced RAG architectures with LangChain and LlamaIndex, and secure private hosting on vLLM and Ollama within isolated enterprise VPCs.

## Overview
AdaptNXT is an enterprise Generative AI development company engineering production-ready LLM systems. We help engineering and enterprise teams move beyond brittle proof-of-concepts into resilient, private, and high-throughput agentic architectures with strict data privacy guarantees.

## Core Capabilities
### Custom LLM Fine-Tuning (LoRA / QLoRA)
Parameter-efficient fine-tuning on open-source weights (Llama 3.3, DeepSeek, Mistral) for enterprise domain terminology, compliance rules, and proprietary internal processes.

### Advanced Enterprise RAG
Grounding LLMs in proprietary knowledge bases using hybrid dense/sparse vector search, Cohere re-ranking, and metadata filtering with Pinecone, Qdrant, Milvus, and PGVector.

### Agentic Workflows & Multi-Agent Systems
Orchestrating autonomous planning, tool usage, memory caches, and reasoning loops using LangChain, LlamaIndex, and CrewAI for end-to-end task execution.

### Private On-Premise & Air-Gapped Hosting
High-throughput model serving using vLLM, TensorRT-LLM, and Ollama within air-gapped VPCs or bare-metal GPU clusters with zero third-party data leakage.

## Technology Stack
Llama 3.3, DeepSeek R1/V3, Mistral, vLLM, LangChain, LlamaIndex, Qdrant, Pinecone, PGVector, NVIDIA Triton, Ray Serve

## Frequently Asked Questions
### What is the difference between RAG and LLM Fine-tuning?
RAG retrieves external domain facts at query time from a vector database, making it ideal for dynamic documents. Fine-tuning modifies internal model weights via PEFT/LoRA to adopt specialized task behaviors and stylistic patterns.

### How do you ensure enterprise data privacy?
We deploy models strictly within your private AWS/Azure/GCP VPC or local on-premise hardware using vLLM. No prompt data, tokens, or weights ever leave your security perimeter.

### What open-source models do you support for production deployment?
We specialize in Llama 3.3 (70B/8B), DeepSeek R1 and V3, Mistral NeMo/Large, and specialized embedding models like BGE and Cohere.
