The services doing the work
Read off the slides, not guessed. Each card says what that service did in this build, and links to the page explaining the capability and how to run it somewhere else.
InstructLab
The open-source pipeline behind the fine-tune: documents become Q&A pairs in YAML, synthetic data is generated from them, then the adapter is trained with LoRA. Model-agnostic, and it ran on a laptop.
Amazon Bedrock
The workstation. Claude Sonnet 3.7, Amazon Nova Pro and the custom model are all served from one place.
Amazon Bedrock Custom Model Import
Serves the fine-tuned Llama 3.1 3B as the UG Specialist, so the trained model needs no cluster of its own.
CrewAI
Runs the crew: Q&A agent, agenda producer, header generator, speaker finder, GitHub planner and the UG Specialist.
AWS App Runner
Runs the agent container. The whole system came to about 30 euros a month.
Amazon ECR
Holds the container image App Runner pulls.
Amazon S3
Stores the trained model before Bedrock imports it.
Llama 3.1 3B
The open-weights base model that became the UG Specialist, adapted with LoRA rather than retrained.
Amazon Nova Pro
The agent model, and the teacher that generated the synthetic training data.
Claude Sonnet 3.7
Answers the open questions in the Q&A agent.
Red Hat OpenShift AI
The alternative to training on a Mac: the same run as a Jupyter environment or an OpenShift pipeline.
Slides from the talk
From MacBook to Bedrock, with Philipp Bergsmann. The slides that carry the architecture.

The five steps from a document to a working Slack bot: document knowledge, a Q and A YAML file, synthetic data generation, training, inference. Slide from the From MacBook to Bedrock deck.

Synthetic data generation: a taxonomy feeds a teacher model, Mistral Small 24B, which scales the set thirty times into a training and test dataset. Slide from the From MacBook to Bedrock deck.

The first agent crew: a Meetup Manager on Amazon Nova Pro delegating to a GitHub Planner, a Speaker Finder and an Agenda Producer, with Chroma as short term memory. Slide from the From MacBook to Bedrock deck.

The second crew: Slack talks to a Q and A agent on Claude Sonnet 3.7, a User Group Specialist on a custom Llama 3B model and a Speaker Finder on Amazon Nova Pro. Slide from the From MacBook to Bedrock deck.

The running cost of the entire setup, about thirty euro a month. Slide from the From MacBook to Bedrock deck.
