Six GenAI Paradigms We Build With

From fine-tuned LLMs to production RAG pipelines — we match the right generative AI technique to your enterprise use case.

LLM Fine-Tuning & RLHF

Adapting large language models to your domain and tone through supervised fine-tuning, instruction tuning, and reinforcement learning from human feedback. We use parameter-efficient methods (LoRA, QLoRA) to cut compute costs while achieving state-of-the-art domain accuracy — without leaking your data to third-party APIs.

LoRA / QLoRA RLHF Instruction Tuning DPO

Retrieval-Augmented Generation (RAG)

Building knowledge-grounded AI systems that retrieve relevant context from your document corpus before generating answers — dramatically reducing hallucination and keeping responses factually anchored to your enterprise data. We design chunking strategies, embedding pipelines, rerankers, and hybrid search for production-grade accuracy.

Vector Search Reranking Hybrid Retrieval

Text-to-Image & Diffusion Models

Deploying and fine-tuning diffusion-based image generation systems — Stable Diffusion, ControlNet, and custom LoRA adaptations — for brand-consistent visual content, product imagery, synthetic training data generation, and creative workflows. We handle both cloud-hosted and on-premise deployments with safety filters.

Stable Diffusion ControlNet Image LoRA

Multi-Modal AI (Vision + Language)

Building systems that reason across images, documents, and text simultaneously — enabling document understanding, visual question answering, image captioning, and product analysis at scale. We work with vision-language models (VLMs) including GPT-4V, LLaVA, and Idefics for enterprise document and media pipelines.

VLMs Document AI Visual QA

Code Generation & AI Pair Programming

Deploying code-specialized LLMs for test generation, code review automation, legacy migration, API documentation, and developer productivity tools — integrated into your CI/CD pipeline or IDE. We fine-tune on your codebase to produce context-aware suggestions aligned to your team's conventions and patterns.

Prompt Engineering & Chain-of-Thought

Systematically designing, testing, and optimizing prompt pipelines — including chain-of-thought reasoning, few-shot exemplars, constitutional AI constraints, and agentic tool-use patterns — to maximize reliability and accuracy without fine-tuning. We build prompt management systems with version control and A/B evaluation frameworks.

Use Case Definition

We start by mapping the exact generative AI opportunity to measurable business outcomes — defining what gets generated, for whom, and under what constraints. This scoping prevents over-engineering and ensures every subsequent decision is anchored to business value rather than technical novelty.

  • Stakeholder workshops to identify high-ROI generative AI use cases
  • Input/output specification: what goes in, what must come out
  • Accuracy, latency, and safety requirements defined upfront
  • Build vs. API vs. fine-tune decision framework
Step 02 of 05

Data Curation & Preparation

The quality of generative AI output is bounded by the quality of the data it learns from. We collect, clean, deduplicate, and structure your enterprise data — documents, logs, code, customer interactions — into training and retrieval corpora with PII scrubbing, format normalization, and quality scoring baked in.

  • Document ingestion pipelines with format normalization (PDF, DOCX, HTML)
  • PII detection and anonymization for compliance-safe training sets
  • Chunking strategy design for optimal retrieval in RAG systems
  • Instruction dataset construction with quality filtering
Step 03 of 05

Model Selection & Fine-tuning

We select the optimal base model — open-source or proprietary — and apply the minimum necessary adaptation: from zero-shot prompting to full fine-tuning with RLHF, depending on the accuracy gap. Every experiment is benchmarked against domain-specific evaluation suites before any training cost is committed.

  • Model sizing: balancing inference cost against capability requirements
  • LoRA and QLoRA fine-tuning with multi-GPU training infrastructure
  • RAG pipeline construction: embeddings, vector DB, reranker stack
  • Prompt engineering and chain-of-thought optimization
Step 04 of 05

Safety & Hallucination Testing

No generative AI system ships without passing a systematic safety battery. We run hallucination benchmarks, adversarial red-teaming, bias audits, and output consistency tests — then implement factual grounding mechanisms, refusal training, and confidence thresholds to prevent unsafe or inaccurate generations reaching end users.

  • Hallucination rate measurement against ground-truth knowledge
  • Adversarial prompt injection and jailbreak resistance testing
  • Bias and toxicity screening across demographic dimensions
  • Factual consistency scoring with citation verification for RAG
Step 05 of 05

Production Deployment & Guardrails

Deployment is a system engineering challenge, not just model serving. We build vLLM or TGI-based inference stacks with autoscaling, output guardrails, input sanitization, rate limiting, audit logging, and cost monitoring — ensuring the system stays safe, fast, and cost-efficient as usage grows.

  • vLLM / TGI inference serving with autoscaling and batching
  • Output guardrails: topic filtering, PII redaction, length enforcement
  • Audit logging of all generations for compliance and review
  • Cost monitoring dashboards with token budget alerting

Real-World Impact

GenAI Problems We've Solved

Enterprise generative AI deployments across industries — each delivering measurable productivity and quality gains from day one.

Enterprise Knowledge Assistant

Finance / Legal

Core Challenge

Knowledge workers in finance and legal spend 30–40% of their time searching internal documents, policies, and case precedents for answers that exist somewhere in the organization but cannot be surfaced quickly. Generic LLM chatbots hallucinate facts and cite non-existent precedents.

Who Benefits

Law firms, financial institutions, compliance teams, and insurance companies that need accurate, cited answers from their proprietary document corpus — with full audit trails and source attribution for every response.

AI Content Creation Platform

Media

Core Challenge

Media companies need to produce high volumes of on-brand written and visual content across formats and languages — at a scale and speed that human teams alone cannot maintain, while preserving editorial quality and brand voice consistency.

Who Benefits

Publishing houses, marketing agencies, e-commerce platforms, and media companies that need a production-grade content pipeline for articles, product descriptions, ad copy, and social media — with human-in-the-loop review workflows.

Code Review & Generation

Software Dev

Core Challenge

Engineering teams lose significant velocity on code review bottlenecks, repetitive boilerplate generation, and legacy code documentation — tasks where AI assistance can provide 60–80% of the effort while keeping engineers focused on architecture and complex logic.

Who Benefits

Software development teams, platform engineering groups, and tech companies that want a codebase-aware AI assistant integrated into their IDE and CI/CD — fine-tuned on their own repositories to produce contextually appropriate suggestions.

Customer-Facing GenAI Chatbot

Retail

Core Challenge

Retail customer service teams face high volumes of repetitive queries — order status, product recommendations, returns — that frustrate customers when handled by rigid rule-based bots but are too costly to handle entirely through human agents at scale.

Who Benefits

Retailers, e-commerce platforms, and consumer brands that need a conversational AI layer handling tier-1 customer queries with personalized, product-aware responses — integrated with their CRM, order management, and inventory systems.

Frequently Asked

Generative AI Questions

Answers to the questions engineering leaders, CTOs, and product teams ask before starting a GenAI engagement with Presear Softwares.

Ask Our GenAI Team
Can you host the model on our own servers?
Yes — on-premise and private cloud deployment is a first-class option for all our GenAI systems. We containerize models using Docker and Kubernetes, deploy inference servers (vLLM, TGI) on your GPU infrastructure, and never require your data to leave your network. For air-gapped environments, we support fully offline deployments with open-source models like LLaMA 3 and Mistral. Data residency and sovereignty requirements are handled by design, not afterthought.
How do you prevent hallucinations in production?
Hallucination mitigation is a layered strategy. For knowledge tasks, RAG grounds every response in retrieved source documents — and we implement citation verification to flag when the model's answer diverges from its sources. For fine-tuned models, we run calibration benchmarks and implement confidence thresholds. At the output layer, we add factual consistency classifiers that can block or flag low-confidence generations before they reach users. No single technique eliminates hallucinations; the combination of grounding, fine-tuning, and post-generation checks gets rates low enough for production.
What's the difference between RAG and fine-tuning?
RAG retrieves relevant documents at inference time and injects them as context — it's best for keeping a model current with your knowledge base without retraining. Fine-tuning adjusts the model's weights on your data — it's best for teaching a specific style, tone, task format, or domain vocabulary that prompting alone can't achieve. Most enterprise systems need both: fine-tuning for behavior and format, RAG for factual grounding. We evaluate the accuracy gap with your target task before recommending either, since fine-tuning has significant compute and data costs that aren't always justified.
Do you support custom LLMs built from scratch?
We can — but we almost never recommend it. Training a domain-specific LLM from scratch requires billions of tokens of high-quality domain text and millions in compute. The more practical and cost-effective path is fine-tuning an existing open-source model (LLaMA, Mistral, Falcon) on your data, which achieves domain specialization at a fraction of the cost. We reserve from-scratch training recommendations for genuinely unique modalities or languages with no existing foundation model coverage. We'll always tell you which approach makes economic sense for your situation.
How do you handle data privacy for training?
Data privacy is designed in from the start. We implement PII detection and anonymization before any data enters a training pipeline, use differential privacy techniques where regulatory requirements demand it, and ensure training data never leaves your designated environment. For API-based systems (GPT-4, Claude), we configure zero data retention settings with the provider. We produce data handling documentation that satisfies GDPR Article 30 record-keeping requirements and assist with DPA addendums if your providers require them.
