Technology

The stack behind production AI at T7.

We're intentionally model- and cloud-agnostic. Here's the toolkit we reach for — and how we choose per project.

Large Language Models

We're model-agnostic. Every project picks the best model per task based on latency, cost, evaluation scores and data-residency needs — not vendor lock-in.

  • OpenAI GPT-4o / o-series
  • Anthropic Claude Sonnet & Opus
  • Google Gemini 2.0
  • Meta Llama 3.1 (self-hosted)
  • Mistral Large & open models

Vector databases & retrieval

Start simple, scale when the workload demands it. Postgres + pgvector covers most enterprise RAG cheaply; specialised stores step in for high-cardinality, high-QPS or geo-replicated workloads.

  • pgvector (Postgres)
  • Pinecone
  • Weaviate
  • Qdrant
  • Elasticsearch hybrid search

Frameworks & orchestration

We favour thin, testable orchestration over heavyweight abstractions. Frameworks accelerate the 80% — we always own the critical paths in plain code.

  • LangChain / LangGraph
  • LlamaIndex
  • Semantic Kernel
  • Model Context Protocol (MCP)
  • Custom TypeScript / Python agents

Cloud & infrastructure

Deploy where your data lives. Multi-cloud experience means we can bring workloads to your existing spend commitments, or run entirely inside your VPC.

  • AWS (Bedrock, Lambda, ECS)
  • Azure (OpenAI, AKS, Functions)
  • Google Cloud (Vertex AI, GKE)
  • Docker + Kubernetes
  • Serverless edge (Cloudflare, Vercel)

Data platform

Great AI needs a solid data foundation. We invest early in schema, observability and lineage — not just prompts.

  • PostgreSQL (primary)
  • Snowflake / BigQuery
  • ClickHouse (analytics)
  • Redis / Upstash
  • dbt for transformations

Frontend & product engineering

Type-safe, accessible, fast. Shipping AI features that people actually use requires product-quality UX — streaming responses, optimistic UI, empty and error states.

  • React + TypeScript
  • Next.js / Vite
  • Tailwind CSS + shadcn
  • TanStack Query
  • Framer Motion

Voice, OCR & multimodal

Voice and document AI are where LLMs meet the physical world. We combine best-in-class ASR, TTS and OCR with domain-specific post-processing.

  • OpenAI Whisper / Realtime API
  • ElevenLabs & Deepgram
  • Azure Document Intelligence
  • Tesseract / PaddleOCR
  • Twilio & LiveKit

Evaluation & observability

You cannot ship what you cannot measure. Every T7 AI system ships with automated evals, request-level traces and drift monitors from day one.

  • LangSmith / LangFuse
  • Braintrust evals
  • OpenTelemetry
  • Grafana + Prometheus
  • Sentry

Security & governance

Enterprise deployments need guardrails, audit trails and policy-based access — built into the app, not bolted on.

  • Row-level security (Postgres RLS)
  • OAuth 2.0 / SSO / SCIM
  • Prompt injection defenses
  • PII detection & redaction
  • Audit logging
