Image Upload + Thumbnail Pipeline

easy infra problem: image upload + thumbnail pipeline

Source: chini-train synth generator v0.1

Prompt

Design a system for: image upload + thumbnail pipeline (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: $552 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.

Constraints

Max components: 8
Required behaviors: storage, queue, circuitbreaker
Monthly budget: $552

Stress scenarios

Baseline traffic

baseline

Steady ambient load with no failures.

Latency injection

latency

Extra latency injected into a critical component. Tests degradation behavior under slow downstreams.

Pass criteria (overall)

Min stability score: 67
Max drop rate: 13.6%
Min delivery rate: 80.0%
Max errors: 10

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-0215-dp2-infra \
  --provider openrouter --model google/gemini-2.0-flash-001 \
