People are really enjoying our full workshops showing end to end walkthroughs of real production workflows! This is a rare double header with @braintrust's Giran Moodley and @OussamaHaff walking though the real life AI engineering behind @thetrainline, Europe's #1 most downloaded rail app with 27m MAU and £5.3B in ticket sales! the workshop bundles several important lessons: - break down monolithic LLM calls into specialized stages (e.g., triage, policy review, and reply generation) - how to monitor latency, token usage, and costs effectively with end-to-end tracing of agentic flows - using "golden sets" (a curated set of test inputs) to identify failure modes - how to move from local development to a managed environment where prompts and scoring functions are version-controlled - how to allow non-technical team members to collaborate and update model parameters without code changes - how to identify production regressions, replay failures, and apply targeted fixes to improve system reliability continuously enjoy!
