RISC-V is also open. That “some reason” is likely to be power/performance levels being quite far from ARM & Intel for consumer devices.

China is building out RISC-V, just like they are leading actually-open AI.

Weirdly, the authoritarian state is the one saving us from our own digital authoritarians.

> they are leading actually-open AI.

How are they leading? If I parse this correctly, "actually" open would mean fully open data training and weights? Then, by this definition, I'm only aware of Olmo (AllenAI - Seattle), Apertus (Swiss) and to some degree (unclear what data was actually published) Nemotron (Nvda, US). What are some examples of chinese similar models? (I'm not aware of any).

RISC-V is slow though

RISC-V is an ISA.

There's nothing inherently slow about it, anymore than there is anything inherently slow about x86 or ARM.

High performance microarchitecture implementations are definitely possible. Some of them are available for licensing.

At least one of them (Tenstorrent Ascalon) has been tapped out into a chip and will show up in development boards later this year.
