LLMs & ML features

AI Integration

LLMs where they earn their keep. Claude, OpenAI, and embedding-based features integrated into your product with fallbacks, guardrails, and a real eval loop. No throwing a chatbot at everything.

What you get

AI that earns its keep

Four things we deliver on every AI integration — not marketing claims, engineering practices.

  • Prompt library + evals

    Versioned prompts with a test suite. We measure output quality against real examples, not vibes.

  • Model + fallback wiring

    Primary model with an automatic fallback. When OpenAI rate-limits, Claude picks up. No broken features.

  • Rate & cost controls

    Per-user quotas, cached completions, and budget alerts. You see token spend before it surprises you.

  • User-facing UX for AI outputs

    Streaming responses, clear error states, and honest uncertainty signals. AI that users actually trust.

Who this is for

Use cases

  • Products adding their first real AI feature without the chatbot-on-everything trap
  • Teams who need LLM outputs measured and tested before shipping
  • Applications that require model fallbacks and cost guardrails
  • Products using semantic search or retrieval-augmented generation
  • Founders who want to understand token cost and quality before committing
  • Systems that need human-in-the-loop controls for sensitive outputs

How we work

Our process

Four phases. Prototype before commit. Evals before launch. No vibes-based shipping.

  1. Discovery

    What's the real AI use case? Is it worth the token cost? We stress-test the idea before committing.

  2. Prototype

    Build a thin slice, wire up a real eval set, and prove the outputs hold up on your actual data.

  3. Build

    Production integration with monitoring, fallback models, cost controls, and a proper prompt registry.

  4. Launch

    Ship with guardrails: rate limits, content filters, human-in-the-loop where it matters, and live evals.

Proof of work

We practise what we build

Client work is under NDA. Here's what we ship in the open.

Before you ask

Frequently asked questions

Which LLM should I use — OpenAI, Claude, or something else?

Depends on the task. Claude is stronger at long-context reasoning and structured instructions; OpenAI has the mature ecosystem and best function-calling; Gemini is cheap at scale; open-source models (Llama, Qwen) make sense if data sovereignty matters. We run your real prompts against 2–3 models during prototyping and pick based on measured quality, latency, and cost — not marketing.

How do you handle hallucinations?

Three layers: retrieval-augmented generation so the model cites your actual data, structured output schemas that reject malformed responses, and a human-review step for anything that touches money, health, or legal outcomes. We also run an eval suite on every prompt change so regressions get caught before deploy.

What does "eval" actually mean?

An eval is a test suite for AI outputs. We collect 50–200 real examples with expected answers (or quality rubrics), then score every model change against them automatically. It's the difference between "seems fine when I tried it" and "95% accuracy on the customer support dataset". Without evals, you're flying blind.

How do you control costs at scale?

Per-user token quotas, aggressive caching of repeated completions, prompt compression, routing cheap queries to smaller models, and budget alerts that page us before you get a £10k surprise bill. We also track cost-per-request in Langfuse so you know exactly which feature is expensive and why.

Is it safe to send our data to cloud LLMs?

Depends on your data and regulator. OpenAI and Anthropic offer zero-retention enterprise agreements and don't train on API data. For UK GDPR or NHS-adjacent workloads we use Azure OpenAI with EU data residency, or self-host open-source models on your own infrastructure. We advise on the trade-offs before a single token leaves your network.
