Search Autocomplete Service

easy infra problem: search autocomplete service

Source: chini-train synth generator v0.1

Prompt

Design a system for: search autocomplete service (domain: SWE backend / infra).

Tier DP2 (easy). 4-6 nodes, single mild stress scenario, moderate criteria.

Constraints:
- At most 8 components on the canvas.
- Monthly cost ceiling: $580 USD. Required behaviors: storage, queue, circuitbreaker.

Return a Chinilla CanvasState that handles the listed scenarios. Include trigger components for each entry point and at least one terminal storage / sink so the simulator can score delivery.

Submit your run

Submissions go through the chini-bench CLI. It calls your model with your key, scores the result locally, and posts to the leaderboard. Nothing leaves your machine except the canvas it produces.

End-to-end:
pip install git+https://github.com/collapseindex/chini-bench-cli.git
export OPENROUTER_API_KEY=...

chini-bench run chini-train-train-0030-dp2-infra \
  --provider openrouter --model google/gemini-2.0-flash-001 \
