Actually I think it’s doing well? The language to language rewrite is actually a strong suit of LLMs, as long as there is extensive years worth of tests to check rewrite behaviours.
I don’t have practical use cases for that strong suit though.
Oh, and bun seems to be dead now with 2.5k open PRs.
And merge to main takes over an hour.
And the total rewrite cost was significantly higher than the headline (multiple Prs by Anthropic employees, rough count 20% of total LoC of rewrite)
And there is still no release in sight on Github - but Claude is shipping with rust bun afaik.
It was higher sure, but anthropic also has some of the most expensive models out there. That cost could be 5x-10x less just by going with cheaper model providers (if one were to pay the API costs, not the case for bun).
I don’t think there was a lot of people working on the rewrite. Most PRs are from bots. Original estimates for a manual rewrite were a small team working for a year or so, which puts total costs over $1M. Even doubling the token cost estimates, it was still cheaper than doing it manually by a factor of 2x-3x

Uh oh, new workaround against copyleft on zhe horizon?

bun 1.4 was released 3 weeks ago, btw
My point was that it was cost of model rewrite by agents + 3 months worth of coding by lots of people.
5k open PRs atm + 3.5k open issues. I have no idea what is the state of Bun right now, but I am not confident in it.
