LLM System Design Benchmark
The LLM System Design Benchmark evaluates the performance of various LLMs on system design tasks. Nine models were tested on nine problems, with transcripts scored by independent judges across five dimensions. The results show a ranking of models based on their mean scores, with 'kimi-k' leading the benchmark.
- ▪The benchmark assesses how well different LLMs perform on system design tasks.
- ▪Nine models were evaluated on nine problems, resulting in a total of 81 scored transcripts.
- ▪The top-ranked model is 'kimi-k' with a mean score of 2.64.

LLM System Design Benchmark What This IsSection titled “What This Is” This benchmark evaluates how well different LLMs perform on system design tasks. Each model receives the same cold system design prompt — no examples, no hints — and produces a complete design with architecture, capacity estimation, tradeoffs, and failure analysis. Independent LLM judges then score every transcript on 5 dimensions. I evaluated 9 models on 9 problems with 3 judges — 81 transcripts scored in total. See the methodology. Any feedback or request? Please submit an issue.
