## Summary

MoE Cost Analyzer is an open-source benchmarking tool that helps teams decide whether to switch from dense LLMs to Mixture-of-Experts models. It takes a JSON file of real production prompts, runs live API calls against both model types via OpenRouter, and measures actual latency and cost per query. A validation run on 100 sentiment-analysis tasks comparing Google Gemma dense vs. MoE variants showed MoE was 20% cheaper and 25.5% faster at median load. The CLI tool supports configurable SLA thresholds, outputs a color-coded terminal table, per-query CSV, and a single recommendation string. It includes retry logic, dry-run mode, and 18 passing tests. The project was built using NEO, an autonomous AI engineering agent.

## Questions this post answers

### Is a mixture-of-experts model actually cheaper and faster than a dense model in practice?

In a live 200-call benchmark comparing dense google/gemma-4-31b-it against MoE google/gemma-4-26b-a4b-it on 100 sentiment-analysis tasks via OpenRouter, the MoE model was 20% cheaper per token and 25.5% faster on average latency, with identical output token counts (4,939 total) and zero errors. The speed advantage narrowed from 27% at P50 to 13% at P95 under tail latency conditions.

_Developers weighing a switch to MoE architecture can track real benchmarking approaches like this on daily.dev._

### How can I decide whether to switch from a dense LLM to a Mixture-of-Experts model for my own production workload?

Run live API calls against both models using your own 50-200 production prompts, set latency and cost SLA thresholds via flags like --sla-latency-ms and --sla-cost-per-1k, and let a decision matrix return one of three verdicts: USE MoE, MARGINAL, or STICK WITH DENSE. This avoids relying on generic benchmarks that may not reflect your traffic pattern or SLA needs.

_Teams comparing LLM architectures for cost and latency tradeoffs can follow tooling discussions like this on daily.dev._
