Generative AI training teaches individuals and teams how to use AI systems that generate text, code, images, and other content — including tools such as ChatGPT, Claude, Gemini, and Microsoft Copilot. JBI's Generative AI training courses are suitable for business professionals, developers, analysts, managers, and technical leaders who want to use AI more effectively in their work, improve productivity, or build AI-powered applications and workflows.
Prompt engineering is the practice of designing and structuring inputs to AI language models to obtain accurate, relevant, and consistent outputs. Effective prompt engineering helps users get better results from AI tools, reduce errors and hallucinations, and build reliable AI-assisted workflows. JBI offers dedicated prompt engineering courses for general LLM use, ChatGPT-specific use, and advanced GPT and LLM applications.
Yes. All JBI Generative AI and LLM training courses are available as live online instructor-led sessions, with the same hands-on exercises and expert instruction as classroom delivery. Online training is available to delegates across the UK and internationally.
A Large Language Model (LLM) is an AI system trained on large amounts of text data to understand and generate human language. LLMs such as GPT-4, Claude, Llama, and Gemini are the foundation of modern generative AI tools including ChatGPT and Microsoft Copilot. JBI's LLM training courses cover how LLMs work, their capabilities and limitations, how to use them effectively through prompt engineering, and how to build applications on top of LLM APIs.
Yes. All JBI Generative AI training courses can be delivered as bespoke closed-group programmes for corporate teams. Content is tailored to your team's role, existing AI experience, specific tools in use, and business objectives. JBI has delivered bespoke Generative AI and LLM training to teams in financial services, professional services, retail, media, the public sector, and technology organisations across the UK.
Retrieval-Augmented Generation (RAG) is a technique that enables AI language models to access and reason over external, up-to-date knowledge sources — such as internal documents, databases, or APIs — rather than relying solely on their training data. RAG is widely used to ground AI responses in factual, organisation-specific information. JBI covers RAG in several courses including Build Agentic AIs with Python, RAG and MCP and Build a Chatbot with Python, RAG and OpenAI.
Model Control Protocol (MCP) is an open standard for connecting AI models to tools, data sources, and external services in a structured and interoperable way. It provides a consistent interface for AI agents to access APIs, databases, file systems, and other resources. JBI offers a dedicated MCP training course covering server and client implementation, Claude API integration, and production deployment of MCP-enabled AI systems.
Yes. JBI Training offers a 3-day LangChain for AI Agents training course covering LLM workflow design, chain construction, agent development, memory systems, retrieval integration, and production deployment using the LangChain framework in Python. The course is designed for developers building LLM-powered applications and AI agent systems.
Prompt engineering focuses on crafting effective inputs to AI models to improve the quality and consistency of outputs — a skill relevant to any user of AI tools, technical or non-technical. Building AI applications with LLMs involves programming against model APIs, designing application architecture, managing context and memory, handling tool use and retrieval, and deploying AI-powered systems. JBI offers training for both — from introductory prompt engineering to advanced LLM application development.
Yes. JBI's Generative AI and LLM training range includes courses for complete beginners such as Harnessing Generative AI, Prompt Engineering for ChatGPT, and AI Prompt Engineering, which require no prior programming or AI experience. Developer-focused courses such as LangChain for AI Agents and Mastering LLMs require programming experience and prior familiarity with AI concepts. Each course page specifies the recommended experience level and prerequisites.
JBI Training regularly reviews and updates its Generative AI and LLM training content to keep pace with the rapid developments in this field. New model releases, updated prompt engineering best practices, emerging frameworks such as LangChain and MCP, and evolving governance requirements all feed into JBI's course refresh cycle. Whether you are learning about ChatGPT, Claude, Gemini, or open-source LLMs, JBI's training reflects how these tools are being used in practice today — not how they worked a year ago.
