LLM Integration & RAG

Production-grade GPT, Claude, Gemini and open-source LLMs — grounded in your data.

We help enterprises embed large language models into products and internal workflows — with retrieval-augmented generation, evaluation harnesses and cost controls built in from day one.

Overview

Most LLM projects fail not because the model is wrong, but because the surrounding system is missing. T7 Solution builds the retrieval layer, guardrails, evaluation loops and observability that turn a prompt into a product.

We work across OpenAI, Anthropic, Google, Meta Llama, Mistral and self-hosted stacks — choosing the right model per task, not per hype cycle. Our RAG pipelines are grounded in your documents, databases and APIs, with citations and traceability by default.

Every deployment ships with an evaluation suite, prompt versioning, PII redaction and a cost dashboard — so you can scale usage without scaling risk.

What we deliver

Retrieval-Augmented Generation

Vector search, hybrid retrieval, re-ranking and chunking strategies tuned to your corpus.

Fine-tuning & Distillation

Domain adaptation on Llama, Mistral and GPT — plus distillation to smaller, cheaper models.

Prompt Engineering & Evals

Structured prompts, function calling, JSON-mode outputs and automated evaluation with golden datasets.

Guardrails & Safety

PII redaction, jailbreak detection, output validation and human-in-the-loop review.

Cost & Latency Optimisation

Caching, model routing, batching and quantisation to cut inference cost 40–80%.

Observability

Trace-level logging, token accounting, drift detection and A/B testing for prompts and models.

Use cases

Knowledge Assistants

Company-wide Q&A over policies, contracts, product docs and Confluence.

Sales & Support Copilots

Draft replies, summarise tickets, surface next-best-action from CRM data.

Semantic Search

Replace keyword search with meaning-based search across unstructured content.

Content Generation

Brand-safe marketing, product descriptions and personalised outreach at scale.

Challenge

The support team was drowning in repetitive product questions and analysts spent hours writing SQL for one-off reports — while the CFO wanted every AI initiative tied to a P&L number.

Solution

T7 shipped a RAG copilot grounded in product docs, changelog and the customer data warehouse. Model routing sends simple questions to a small local model and complex reasoning to GPT-4-class models. Every response ships with citations and a confidence score; low-confidence answers escalate to a human.

Result

Deflection on Tier-1 support crossed 68% within 90 days. Analyst SQL time dropped by roughly half. Optimized query routing and semantic caching ensured latency remained sub-second.

"T7 didn't sell us a chatbot — they built the retrieval, evals and cost controls we didn't know we needed. It's the first AI project we've shipped that our CFO actually likes."

Frequently asked questions

Which LLM should we use — GPT-4, Claude or open-source?

It depends on task, data sensitivity and cost. We benchmark 2–3 candidates on your data before committing. Many production stacks route between models per query type.

How do you prevent hallucinations?

Retrieval grounding with citations, structured outputs, validation layers, and automated evals against a golden dataset. We measure hallucination rate, not just anecdotes.

Can we host the LLM ourselves?

Yes. We deploy Llama 3, Mistral and other open-source models on your cloud or on-prem GPUs when data residency or cost demands it.

How long does an LLM project take?

A working prototype typically takes 2–4 weeks. Production deployment with guardrails and observability adds 4–8 weeks depending on scope.

How do you keep inference costs under control?

Model routing, semantic caching, prompt compression, batching and — where quality allows — distillation to smaller models. We publish a cost dashboard so every team owns their spend.

What does a typical RAG pipeline look like?

Ingestion → chunking → embeddings → vector store (pgvector, Pinecone or Weaviate) → hybrid retrieval + re-rank → LLM with structured output → eval + trace logging. We tune each stage against your corpus.

Do you handle fine-tuning and DPO?

Yes. We do supervised fine-tuning, LoRA/QLoRA on open-source models, and preference tuning (DPO/RLHF-lite) when you have labelled feedback data.

How do you handle compliance — HIPAA, GDPR, DPDP Act?

Data stays in your cloud region, PII is redacted before it hits third-party APIs, and every request is logged with lineage. We ship the DPIA template and vendor DPAs as part of go-live.

Can this integrate with our existing data warehouse?

Yes — Snowflake, BigQuery, Databricks, Redshift and Postgres are all first-class. We build ELT for the RAG index and keep it in sync via CDC or scheduled refresh.

What ongoing support looks like after launch?

Monthly evals, drift monitoring, prompt/version rollouts, cost tuning and quarterly model upgrades. Most clients stay on a managed-services retainer.

LLM Integration & RAG by location

We deliver llm integration & rag across our core markets, with on-site discovery and local timezone support.
