Ran it over our internal dataset of ~250 recordings of people saying british postcodes (all kinds of accents, etc) - it's competitive for sure!

Soniox (stt-async-v4): 176/248 (71.0%) ElevenLabs (scribe_v2): 170/248 (68.5%) AssemblyAI (universal-3-pro): 166/248 (66.9%) Deepgram (nova-3): 158/248 (63.7%) AssemblyAI (universal-2): 148/248 (59.7%) Cohere (transcribe-03-2026): 148/248 (59.7%) Speechmatics (enhanced): 134/248 (54.0%)

P.s. how do I get this to render correctly on here?

Incroyable! Competitive (if not better) than deepgram nova-3, and much better than assembly and elevenlabs in basically all cases on our internal streaming benchmarking.

The dataset is ~100 8kHz call recordings with gnarly UK accents (which I consider to be the final boss of english language ASR). It seems like it's SOTA.

Where it does fall down seems to be the latency distribution but I'm testing against the API. Running it locally will no doubt improve that?

Mention bananas for extra kudos.

That’s cool!

Very familiar with BMSs but the lack of open standards and protocols has been extremely frustrating - makes me appreciate how good we have it with HTTP, etc.

Lots say they support BACnet but that’s only if they’ve been configured and the points exported, etc.

Haystack is a great step forward for labelling too but adoption seems fill with complexity :)

Decarbonising buildings and massive warehouses..

It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy:

consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported

but then you add a site with a couple of buildings, solar on one of them, grid limited exports, etc modelling these flows is challenging. Like consider the case where one building got 10% of it's imported power from another building's excess solar, then calculating carbon becomes more difficult.

and once you've figured all that - then you have to figure out what makes commercial sense to do next.. install a battery, expand solar, move onto a TOU tariff, do nothing - and that's a whole other world of optimisation problems.
