We've Trained Models for the World's Biggest AI Companies

DigiChum Infotech has provided RLHF (Reinforcement Learning from Human Feedback) resources to train and align large language models for enterprise clients including Apple, Alibaba, and Oracle. This isn't theoretical AI work we know what it takes to build production-grade AI systems.

Apple

Provided RLHF annotation resources for model training and alignment. Our team worked on preference labelling to improve model response quality and safety.

Alibaba

Supported model training pipelines with domain-specific annotation and RLHF feedback loops. Contributed to improving model instruction-following across multilingual datasets.

Oracle

Delivered specialised RLHF resources for enterprise AI system training. Focused on improving model behaviour in structured business and data contexts.

This experience gives us a fundamental understanding of how large language models learn, where they fail, and how to design applications that work reliably in production not just in a demo environment.

Agentic AI

AI Agents We've Built That Automate Real Workflows

Agentic AI means the system can take multi-step actions, make decisions, and complete tasks end-to-end not just answer questions. Here's what we've shipped.

Finance Automation Agent

Expense Categorisation & Monthly Report Agent

Built for a finance dashboard client an AI agent that reads raw expense data (bank statements, invoices, receipts), automatically maps each transaction to the correct accounting category (salaries, rent, vendor payments, travel, etc.), and generates a structured monthly P&L report ready for the finance team to review.

The agent handles ambiguous transactions by asking a clarification question once and remembering the answer for future similar transactions. Over time it learns the client's specific categorisation preferences. Monthly report generation that previously took a finance analyst 4-5 hours now completes in under 3 minutes.

E-Commerce Support Agent

Conversational Order Support Agent for KIC

Built for KIC, an e-commerce client a Swiggy-style conversational support agent that handles the full order support flow without human intervention. Customer types their issue (e.g. "my order is delayed"), the agent presents structured options, guides them through the resolution flow, and where possible completes the action automatically (raising a refund, escalating to delivery partner, placing a reorder).

The agent uses RAG to answer product/policy questions from KIC's knowledge base so "what is your return policy for electronics?" gets an accurate, up-to-date answer pulled from internal documents, not a hallucinated response. Handled 73% of support queries without escalation to a human agent.

HRMS Automation Agents

Employee Onboarding Agent + Offer Letter Generation Agent

Built as part of an HRMS platform two agents that handle the most time-consuming parts of HR operations.

Offer Letter Agent: HR manager enters the candidate name and role. The agent asks 6-8 structured questions (CTC components, joining date, reporting manager, probation period, variable pay structure). It drafts the offer letter, shows it for review, incorporates any changes in natural language ("make the variable 20% instead of 15%"), and sends it to the candidate via email the whole flow takes under 4 minutes.

Onboarding Agent: On day one, triggers a sequence creates accounts across connected systems (email, HRMS, project management tools), sends the welcome email with credentials, schedules week-1 check-in, assigns mandatory training modules, and notifies IT to ship the laptop. Zero manual steps from HR.

Knowledge Base AI That Answers From Your Data

We've implemented RAG pipelines for clients across e-commerce, healthcare, and enterprise connecting LLMs to internal documents, product catalogues, and knowledge bases so the AI answers accurately from real data, not hallucinations.

Our RAG implementations use a consistent production-grade architecture: documents are chunked, embedded, and stored in a vector database (Pinecone or pgvector). At query time, the most relevant chunks are retrieved and passed to the LLM as context. We add a confidence threshold below which the system escalates to a human rather than guessing.

1

Document Ingestion Pipeline

PDFs, Word docs, web pages, and structured data automatically chunked, cleaned, and embedded. Supports incremental updates (new documents sync automatically).

2

Vector Storage & Retrieval

Embeddings stored in Pinecone or pgvector. Semantic search retrieves the most relevant chunks for each query not just keyword matching.

3

LLM with Context Window

Retrieved chunks passed to GPT-4o or Claude as context. The model answers only from what's in the context with source citations.

4

Confidence & Escalation Logic

Below a confidence threshold, the system says "I don't know" or escalates never hallucinates an answer to a business-critical question.

RAG Use Cases We've Built
KIC E-Commerce Support Bot
Product catalogue + return policies + shipping FAQs indexed. Agent answers customer questions accurately from live knowledge base. 73% resolution rate without human escalation.
an EdTech platform EdTech Doubt Bot

LLM Training & RLHF

We've Trained Models for Apple, Alibaba & Oracle

DigiChum Infotech has provided specialised RLHF (Reinforcement Learning from Human Feedback) resources to some of the world's largest AI programmes. Our team has hands-on experience with what it takes to align large language models for production use.

What RLHF Work We Do

RLHF is the process of teaching language models to produce better outputs by having human annotators rank or rate responses. Our team has worked on:

Preference Labelling
Given two model responses, our annotators judge which is better more helpful, more accurate, more appropriate. This preference data trains the reward model used in RLHF.
Instruction-Following Evaluation
Evaluating whether model outputs correctly follow complex, multi-part instructions. Critical for enterprise models that need to follow business rules precisely.
Safety & Alignment Annotation
Identifying harmful, biased, or policy-violating outputs. Providing detailed feedback that helps models learn what NOT to say in sensitive contexts.
Multilingual & Domain-Specific Data
Creating and annotating training data for specific domains (finance, legal, medical) and languages. Our team has worked on Hindi, English, and business-domain datasets.

We Also Fine-Tune Models for Clients

Beyond RLHF annotation, we fine-tune open-source models (LLaMA, Mistral, Phi) for specific client use cases where a general model isn't sufficient.

Domain Fine-Tuning
Train a base model on your industry-specific documents, terminology, and workflows. The result is a model that speaks your domain language naturally not a general model trying to adapt.
Instruction Fine-Tuning
Train models to follow your specific output formats, tone, and business rules consistently critical for automated report generation and structured data extraction.
On-Premise Deployment
For clients with data privacy requirements, we deploy fine-tuned models on your own infrastructure no data leaves your environment. Common for healthcare and finance clients.

We Help You Figure Out Where AI Actually Makes Sense in Your Business

Most businesses don't need AI everywhere. They need it in 2-3 places where it will have a measurable impact. Our consulting engagement helps you find those places and build a plan to get there.

1

AI Readiness Assessment (Week 1)

We map your current workflows, identify the 3-5 highest-friction manual processes, and assess your data quality and availability. Output: a ranked list of AI opportunities with estimated effort and ROI.

2

Use Case Prioritisation (Week 2)

For each opportunity: build vs. buy analysis, data requirements, integration complexity, and risk assessment. We tell you honestly which use cases are worth pursuing and which aren't ready yet.

3

Proof of Concept (Weeks 3–5)

For the top-priority use case, we build a working POC in 2-3 weeks. Real data, real integration, real output not a demo with mock data. You see whether the AI actually works in your context before committing to a full build.

4

Production Roadmap

If the POC validates, we deliver a detailed production roadmap architecture design, data pipeline requirements, integration plan, cost model, and timeline. You can build with us or take it to any team.

What We've Found in Consulting Engagements
Document processing (invoices, forms, reports) is almost always the highest-ROI first AI use case
Most "AI chatbot" requests are actually better solved with a structured decision tree + LLM fallback
RAG only works well if your underlying documentation is well-structured we assess this before recommending it
Fine-tuning is rarely necessary for most enterprise use cases prompt engineering + RAG usually gets you 90% of the way
The biggest AI project failures we've seen: bad data, no human review loop, and trying to automate a process that wasn't well-defined to begin with
