AI & LLM Development

Ship AI features that feel useful, not experimental.

AI and LLM development that turns language models, retrieval and automation into reliable product capabilities, grounded in your data, designed for users and ready for production.

Overview

AI and LLM development that solves real product problems.

Most teams do not need another chatbot demo. They need AI that answers accurately, speeds up operations or unlocks a product experience competitors cannot copy with a prompt alone. Our AI and LLM development service focuses on features that earn their place in the product: clear jobs, measurable outcomes and interfaces people trust.

We design and build LLM-powered workflows across assistants, search, content generation, classification, extraction and agent-style automation. That includes prompt and system design, retrieval-augmented generation (RAG), tool calling, evaluation, guardrails and the product UX that makes the capability feel native, not bolted on.

Whether you are adding intelligence to an existing app or launching an AI-first product, we partner as senior product engineers: pragmatic model choices, secure data handling and a path from prototype to something you can operate in production.

Talk through your brief

  • AI features scoped to a clear user or business outcome

  • Grounded answers with retrieval over your own knowledge and data

  • Production patterns for latency, cost, safety and observability

  • UX designed so people understand what the AI can and cannot do

  • Foundations you can evaluate, iterate and extend after launch

What we provide

AI & LLM capabilities

From first prototype to production-grade intelligence inside your product.

  • LLM-powered product features

    Assistants, copilots, summarisation, rewriting and guided workflows embedded in web and mobile products.

  • RAG & knowledge systems

    Retrieval over docs, tickets, policies and product data so answers stay grounded in what your business actually knows.

  • Agents & tool calling

    Models that take structured actions such as looking up records, triggering workflows, and drafting then confirming, with clear human control points.

  • Automation & extraction

    Classify, extract and transform unstructured content into reliable data your systems can act on.

  • Evaluation & guardrails

    Test sets, quality checks, fallbacks and safety boundaries so behaviour stays predictable as you iterate.

  • Model strategy & integration

    Pragmatic choices across providers and open models, with APIs, auth, cost controls and monitoring built in.

Our approach

How we approach AI & LLM development

Outcome first, then architecture, so you do not scale a clever demo that fails with real users.

  1. 01

    Define the job to be done

    Clarify the user, the decision or task, success metrics and where AI genuinely beats a simpler rule-based approach.

  2. 02

    Prototype with real data

    Build a thin slice against representative content and edge cases. Validate quality, latency and UX before wider investment.

  3. 03

    Harden for production

    Add retrieval, tools, evaluation, logging, rate limits and failure modes. Ship behind product surfaces people can trust.

  4. 04

    Measure & improve

    Instrument quality and cost, gather feedback and iterate prompts, data and workflows as usage grows.

Who it's for

Where AI & LLMs unlock value

When language, unstructured data or repetitive knowledge work is the bottleneck, well-built AI becomes a product advantage.

Customer & support products

Assistants that resolve common questions with grounded answers, and escalate cleanly when they should not guess.

Internal copilots

Tools that help teams draft, search, summarise and action work across policies, CRM notes and operational docs.

Knowledge-heavy platforms

Search and Q&A over large document sets for education, professional services, healthcare ops and similar domains.

Content & workflow automation

Generate, transform and route content with human review where quality or compliance demands it.

Why Spritely

Why Spritely for AI & LLM development

We ship AI as product craft, not as a science experiment parked next to your roadmap.

Product-led AI

We start from the user journey and business outcome, then choose models and architecture that serve that job.

Grounded by default

Where accuracy matters, we design retrieval, citations and fallbacks so the system is useful when it knows and honest when it does not.

Full-stack delivery

UX, APIs, data pipelines and model orchestration stay in one team, with fewer handoffs and fewer brittle demos.

Operable after launch

Logging, evaluation and iteration loops are part of delivery, so quality can improve with real usage.

FAQ

Frequently asked questions about ai & llm development

Still deciding on scope or stack? Get in touch →

What is included in AI & LLM development?

Typically: problem framing, UX for the AI surface, prompt/system design, model integration, retrieval or tools where needed, evaluation, security considerations and production deployment. Scope is defined around the feature you need to ship, not a generic “AI project.”

Do you fine-tune models or use off-the-shelf LLMs?

We start with the simplest approach that hits quality targets, often a strong hosted model plus good retrieval and prompts. Fine-tuning or specialised models come in when evaluation shows they are worth the cost and complexity.

Can you build on our private data securely?

Yes. We design data flows with least-privilege access, clear retention boundaries and provider choices that match your security requirements. Private knowledge stays in retrieval pipelines you control rather than being casually pasted into prompts.

How do you prevent hallucinations?

Through grounding (RAG), constrained outputs, tool use for facts that should be looked up, evaluation against real examples and UX that shows uncertainty or sources. No stack eliminates risk entirely. Good product design makes failure modes visible and recoverable.

How long does an AI feature take to ship?

A focused prototype can land in weeks. A production feature with retrieval, evaluation and polished UX usually takes longer and should ship in phases. Discovery clarifies data readiness and risk before estimates firm up.

Can you add AI to an existing product?

Absolutely. Most engagements extend current web or mobile apps with a new AI capability such as assistant, search, automation or extraction, rather than rebuilding everything from scratch.

Which model providers do you work with?

We are provider-pragmatic: OpenAI, Anthropic, Google and other APIs, plus open models when they fit latency, cost or data constraints. The product requirements drive the choice, not a preferred logo.
