Custom LLM applications built on your data
A general chatbot does not know your contracts, your policies, or your product. We build custom LLM applications and RAG systems that read your own data and answer with citations, at over 90 percent accuracy on domain questions. You can run them privately or on premise. Your data never trains anyone else's model.

Why Generic AI Falls Short for Enterprises
You've tried ChatGPT. It's impressive. But it can't help with your actual business needs:
01
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.
02
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.
03
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.
04
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.
Custom LLM Development ServicesWe 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
- Compliance: SOC 2 Type II ready, HIPAA compliant, GDPR compliant, industry-specific as needed
5 · RAG as a Service
Managed Retrieval, Always Current
- We run your RAG system as an ongoing service, keeping indexes, sources, and models current
- New documents, policies, and data sources added without a new project
- Monthly accuracy reviews against real user queries, with retrieval tuning
- Perfect for: teams that want RAG outcomes without hiring for vector databases and LLM ops
What this work returnsmeasured on delivered projects
Every engagement is scoped to a fixed price and an outcome you can measure, not billable hours.
Speed
10x
faster research & lookup. Teams surface the right answer in seconds instead of digging through documents, wikis and chat threads.
Efficiency
75%
reduction in task time. Multi-step research and drafting that used to take hours runs start to finish in minutes.
Automation
70%
helpdesk automation. Routine tickets are resolved end to end, so your team only handles the genuine exceptions.
THE EDGEFIRM DIFFERENCE
Unlike AI platforms (Glean, Guru):
- Custom-built for your exact needs
- You own the code and infrastructure
- No per-user licensing fees
Unlike large consultancies:
- 4-5 month delivery (not 18-24)
- Fixed-price engagements
- Production code from day one
Unlike DIY approaches:
- Proven architecture patterns
- Complete evaluation framework
- Handles production edge cases
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.
