Earlier quoted context omitted.

I've started to dabble in this only very recently. I have two iCEBreaker boards [0] in the mail right now that I'm excited for. From what I understand, one of the big advantages of the up5k chip (the same chip on the webfpga and the icebreaker) is that there's an open toolchain that runs in seconds (at this chip size), which is not the case in the closed/Vivado/"typical fpga" part of the world. (feel free to correct…

A trick to fit language models of this size it to remove the word to embeddings from the NN, and have a database to look up a dictionary of words and their embeddings. This way the LLL only need the "core" and you do the reverse for loopup again (kind of Text->RAG->LLM->RAG->Text). Have an example here: https://punnerud.github.io/pyspell/ The example have a limited language of around 1000 words, but make it possible…

wow, that tailscale-in-browser demo is wild..!

re: language model - here, the embedding lookup, layers, logits all run on-chip and loops its own output back.

the only off-chip piece is the id to string table, i.e. the chip (once I get it!) will speak token ids and my laptop will print them as letters

No thanks. I remember Mbed. Web-based IDEs are fine for hello world and blinky, but you're going to want a real one very soon, and then you'll find there isn't one because they put all their effort into the shitty web-based one.

Even Arduino has a real app. It's not that hard.

(2019). What's the latest on sub-$100 FPGAs this decade, anything significantly better than the Mojo I picked up back in 2013 to tinker with?

I think there are two interesting ways:

1. Either go for the Gowin FPGAs from China. You can get good boards for cheap from Ali.

2. There are FPGAs that now have a FOSS chain. They are very interesting too.

CMOD S7 by Diligent. Slightly higher than 100 bucks but it is definitely a starter's choice.

Browser-based FPGA tooling is super interesting. Could really lower the barrier for hobbyists, or just make demos much more accessible.

Or, how about you just run the FPGA toolchain on WASM: https://yowasp.org/ ('mad propz' to Catherine/whitequark)

+1. I've used this with Lattice UP5K for some experimental development. I wanted to be able to quickly skip between working on Windows and Linux. Worked well at the time.
