Long conversations overflow the context window. Production agents stay coherent by summarizing history and retrieving long-term memory in parallel, then merging both before the model call.

lightbulbThe Task

Wire the pipeline so Context Assembler branches into both Summarize and Retrieve Memory, then both feed the model before the response.

Gemini FDE Certify {{ roiTitle }} ROI MODULE
savings{{ roiModuleLabel }}

{{ roiQuestion }}

ROI is the number that decides whether your deployment survives the next budget review. Measure the value created (hours saved × loaded cost), subtract the cost to run it (mostly tokens + infra), and express the rest as a percentage and a payback window.

THE FORMULA
ROI % = (value − cost) ÷ cost × 100
value = seats × hrs saved × 4.33 × rate
TOKEN COST REFERENCE · per 1M tokens

IS YOUR SYSTEM ROI-HEALTHY?
check_circlePayback under 90 days — the system recoups its build + run cost within a quarter.
check_circleToken cost < 30% of value — route cheap calls to Flash, reserve Pro for the hard ones.
check_circleValue is attributable — you can tie hours saved to a baseline you measured before launch.

{{ labSubtitle }}

A hub-and-spoke architecture puts one orchestrator at the center. It decomposes the goal, fans work out to independent tools, then merges results. Tools never call each other — they only talk to the hub.

YOUR TASK
The flow on the right answers a revenue question using web search, RAG retrieval, and a calculator. Press Run and watch each hop. One tool will fail — find out which, why, and how the orchestrator recovers.
