LLM Showdown — Lines of Code Across 12 Benchmarks
SynapseKit vs LangChain vs LlamaIndex across every task from hello world to conversation memory. Benchmark #13 (memory) shows the widest LoC gap in the series.
Lines of Code per Benchmark — All 12 Tasks
Memory (#13) is the biggest gap in the series. LangChain requires 17 lines for session store setup + LCEL wiring. SynapseKit does it in 6 — one constructor argument. LlamaIndex sits between at 9. The boilerplate is the price of LangChain's pluggable persistence backends.
