## Skept-o-meter & Hotness

Skept\-o\-meter: High\. Estimated from 10 comments\.

0 comments for the summary\.

Peak rank: \#4

Time in Top 10: 24\.0 hours

Hacksnap ranks recent stories first, then orders each group by points\. Peak rank uses all retained observations\. Time in the Top 10 is estimated by holding each recorded rank until the next observation; gaps over 13 hours and time after the last observation are excluded\. Movement between observations is unknown\.

201 recorded rank observations from 2026\-09\-28T22:01:33\.03543\+00:00 to 2026\-10\-10T23:01:00\.95027\+00:00\.

MicroLLM Lab benchmarks tiny browser LLMs on objective checks and local speed metrics, but the supplied page is UI text with no independent validation or discussion\.

## The brief

MicroLLM Lab is a browser\-based experiment for running tiny language models locally and benchmarking them on objective checks rather than writing quality\. It reports sustained decode speed and pass rates, keeps results on the device, and can generate a shareable performance certificate\. The source explicitly allows a 135M model to fail, framing failure as part of the measurement\.

- Runs tiny LLMs in the browser; benchmark suite can target the active model or every loaded model\.
- Metrics include peak and sustained tokens/s, average sustained speed, suite wall time, and accuracy pass rate on regex or exact\-token checks\.
- A 256\-token sustained speed test is offered; estimates use the last observed tok/s when available\.
- Results and charts stay local; charts use the latest suite per model\.
- Users can define JavaScript benchmark checks, eval'd in the origin and run against decoded model text\.
- Certificate includes device hardware, peak and sustained tokens/s, downloadable as PNG and shareable\.
