“What’s the dream?” I asked Yang Li, cofounder and COO of AI code generator startup Cosine.

“We want to be ten-times bigger than Deep Mind,” came the response.

Of course you do, I thought to myself - and you might too.

But can I encourage you to watch/listen to the full 30-ish minute episode of The BritChips Podcast: Cosine - A New Angle on Sovereign AI before making up your mind.

You see, the market that Cosine is addressing is not all the new stuff.

It’s all the old stuff, the legacy code that has been deeply embedded in commercial enterprises and public sector bodies for years if not decades.

And often there’s nobody left in the organisation who really understands how it works, making maintenance and upgrades an arduous and highly risk-prone exercise.

Yang believes they have the answer - an AI codegen specifically designed to maintain and enhance applications coded in arcane - even archaic - languages.

And Cosine has a USP that Yang believes the ‘usual suspect’ AI codegens can’t beat.

They see Cosine as the only end-to-end sovereign AI coding platform built, owned, and operated entirely in Britain.

The UK government is clearly a believer. Cosine was one of the first startups to be accepted into the government’s £500m Sovereign AI initiative, awarding it access to Isamabard, the UK’s most powerful supercomputer.

So, see what you think.
