Hire LLM and RAG developers in London
Senior engineers on your morning and lunchtime hours, UK GDPR built in, and a fixed price before we start.
Hire senior LLM developers from Clarigo Infotech who have built and run generative AI in production: RAG search, assistants, agents and AI features inside real products. They work across OpenAI, Claude, Gemini and open-source models, and care about evaluation, guardrails and cost. Rates are typically $25 to $49 per hour, and you own all the code.
UK businesses most often hire us for AI automation for service businesses, logistics software and fast MVPs for startups.
