Custom LLM Applications

Your Data, Your Intelligence

Generic ChatGPT can't access your proprietary knowledge, comply with your industry regulations, or integrate with your systems. We build custom LLM solutions that understand your business, protect your data, and deliver 90%+ accuracy on domain-specific tasks.

Why Generic AI Falls Short for Enterprises

You've tried ChatGPT. it's impressive. But it can't help with your actual business needs:

Can't Access Your Proprietary Data

ChatGPT's training ended in 2023. It doesn't know your internal policies, product docs, customer data, or industry-specific terminology.

Can't Comply With Your Regulations

Data sent to OpenAI's servers poses HIPAA/GDPR risks. No audit trail, no data governance, no control over where data is processed.

Can't Integrate With Your Workflows

ChatGPT is standalone—it can't pull from Salesforce, update records, trigger actions, or work within Slack, Teams, or your custom apps.

Hallucinates on Specialized Topics

Generic AI makes up plausible-sounding but incorrect answers on niche topics, can't cite sources, and confidence doesn't match accuracy.

Real Examples of the Gap:

Generic ChatGPT

  • Legal: ""Find precedent cases..."" → May cite non-existent cases
  • Healthcare: Protocol questions → Potentially outdated info
  • Internal: ""How do I submit expenses?"" → ""I don't have access""

Result: can't help with your actual work

Custom LLM

  • Legal: Searches your case DB with exact citations
  • Healthcare: Your approved clinical guidelines + research
  • Internal: Step-by-step from your wiki + link to form

Result: Accurate, sourced answers in seconds

Custom LLMs Built on Your Knowledge

We build intelligent AI systems that understand your business:

1

RAG (Retrieval Augmented Generation)

The Gold Standard for Accuracy

  • Index your Confluence, SharePoint, Google Drive, Slack, and databases into a vector database
  • Every answer includes citations and sources—if info isn't in your data, AI says "I don't know"
  • 90%+ accuracy on domain-specific queries, updates automatically as documents change
  • Perfect for: Internal knowledge management, customer support, legal research, technical documentation
2

Fine-Tuned Models

Custom Models for Your Domain

  • Train GPT-4, Claude, or open-source models on 500-5,000 examples from your business
  • Model learns your patterns, terminology, writing style, and format requirements
  • Deploy to your infrastructure—cloud, on-premise, or air-gapped
  • Perfect for: Legal drafting, medical notes, financial reports, code generation matching your standards
3

AI Agents & Workflows

Multi-Step Task Automation

  • Research agents that search multiple sources and synthesize findings
  • Contract review agents: extract terms, compare to playbook, flag deviations, route for approval
  • Analysis agents that process data and generate insights automatically
  • Technologies: LangChain, LangGraph, tool use, function calling, memory management
4

Private & Secure Deployment

Your Data Never Leaves Your Control

  • Deployment options: Cloud (your AWS/GCP/Azure), on-premise, VPC isolated, or air-gapped
  • End-to-end encryption, role-based access control, audit logging, PII detection
  • Model options: Azure OpenAI (your tenant), AWS Bedrock, or self-hosted Llama/Mistral

Common Questions About Custom LLMs

RAG (Retrieval Augmented Generation) is best for factual Q&A where you need sourced, up-to-date answers—it searches your documents and generates answers with citations. Fine-tuning is best when you need consistent style/format or specialized terminology—it trains the model on your examples. Most successful systems use both: fine-tune for your domain and style, RAG for factual grounding. RAG is cheaper ($50K-100K), faster to deploy, and easier to update. Fine-tuning costs more ($75K-150K) but works offline and delivers more consistent behavior.

For factual Q&A (RAG-based): 90-95% accuracy on domain-specific questions, 98%+ on simple lookup. For generation tasks: 85-90% 'acceptable without edits.' For classification: 95%+ accuracy. We achieve this through evaluation datasets with ground truth, confidence scoring (AI tells you when unsure), human-in-the-loop for low-confidence cases, and continuous monitoring. We set realistic expectations upfront—if 99%+ accuracy isn't achievable with current technology, we'll tell you.

Very common—80% of projects start with data quality issues. Our approach: Phase 1 (Data Audit) assesses completeness, quality, structure, and estimates cleanup effort. Phase 2 (Data Preparation) does automated cleaning and manual curation for critical data. Phase 3 (Continuous Improvement) monitors answer quality and identifies gaps from usage. Sometimes we recommend a 1-2 month data prep phase before building AI. We can also start with your best data and expand coverage over time.

Yes, we specialize in integration. Common integrations: Document repos (Confluence, SharePoint, Google Drive, Notion), Communication (Slack, Teams, email), Databases (SQL, NoSQL, APIs), CRM (Salesforce, HubSpot, Zendesk), File storage (AWS S3, Box, Dropbox), Authentication (SSO via Okta, Azure AD, Google). If you have APIs, we can integrate. If you don't, we can build scheduled exports, webhook listeners, custom connectors, or direct database access.

Security and privacy by design. Data Protection: Encryption at rest (AES-256) and in transit (TLS 1.3), access controls, PII detection and masking, audit logs. Deployment Options: Your cloud account (data never leaves your tenant), on-premise (never leaves your network), VPC isolated, or air-gapped. Compliance: HIPAA BAA available, GDPR data locality and deletion, SOC 2 controls. Model Privacy: Azure OpenAI stays in your tenant, self-hosted models give complete control.

Automatic or scheduled updates. Real-time: Webhook triggers when documents change, auto-reindex with 5-15 minute lag. Scheduled: Daily/weekly/monthly re-indexing, incremental updates (only changed docs). Version Control: Maintain document history, query specific versions, track when information changed. Most systems use a combination: real-time for critical docs, nightly batch for everything else.

Absolutely. We design for flexibility. Model options: OpenAI (GPT-4, GPT-3.5), Anthropic (Claude 3.5), Azure OpenAI (in your tenant), AWS Bedrock (Claude, Llama, Mistral in your AWS), or self-hosted open-source (Llama 3.1, Mistral, Mixtral). We build an abstraction layer so you're not locked into one provider—you can start with OpenAI and switch to Claude later, A/B test models, or route based on query complexity.
