The key seems to be that you take the transcript of a model working within a problem domain that it’s not yet good at or where the context doesn’t match it’s original training and then you continually retrain it based on its efforts and guidance from a human or other expert. You end up with a specialty model in a given domain that keeps getting better at that domain, just like a human.

The hard part is likely when someone proves some “fact” which the models knows and has had reinforced by this training is no longer true. The model will take time to “come around” to understand this new situation. But this isn’t unlike the general populous. At scale humans accept new things slowly.

We do still have open source hardware but that's the last line of defense against actions like this, not the first. They'll target distribution which will affect open source and proprietary hardware equally. You need to kill this sort of legislation in its crib.

Just print the code to do what ever is disallowed on a t-shirt, ala DVDCSS. Is that not a legitimate way around things like this?

I don’t think the right question is “should vaccines be optional?” I think it’s “to what extent should public and private institutions be expected to accommodate people who, for no other reason than ignorance, choose to opt out of the collective responsibility to public health?”

Am I allowed, as a business owner, to pass on an antivax candidate? Am I, as a school administrator, permitted to keep an unvaccinated child from my school system?

Vaccines were always optional in the sense nobody ties you down and makes you take them, and certainly all requirements have exceptions for people with, i.e, immune system issues.

In New York State USA your child must be vaccinated to attend public school: https://www.health.ny.gov/prevention/immunization/schools/sc...

So far, this hasn’t been overturned by the courts. It’s been in place for a few years now.

Ingesting multiple code files will take forever in prompt processing without a GPU though, tg will be the least of your worries. Especially when you don't append but change it in random places so caching doesn't work.
bradfa · 18 days ago
A FIM or completion model like this won't have a large prompt and caching doesn't work anyways (per their notes). It'll get maybe a few thousand tokens in a prompt, maximum. For a 1.5B model, you should expect usable CPU-only inference on a modern CPU, like at least hundreds of tokens per second of prefill and tens of tokens per second of generation, which is decently usable in terms of responsiveness.

How easy is it to re-train these to specific subset of programming languages? Could there be a "ruby+rails+html" version, etc?
bradfa · 18 days ago
I'd love to be able to take an open model like this and feed it the codebases that I work on regularly in order to improve its performance for less "hip/modern" languages and frameworks. It would be awesome to see a blog post about how normal users can find tune these models and rough cost estimates with examples!

This brings up a much larger discussion. How bad are LLMs at engineering? Would you trust one to build a high voltage circuit? How about a bridge?
bradfa · 21 days ago
I don't trust an LLM to write software for me without human verification, but it's not like it's that hard to verify what it writes if you understand how to write code yourself. I expect even when an LLM can layout a high voltage circuit or design a bridge that most organizations who carry liability would still be sure to audit the design with a set or two of intelligent and trained human eyes.

If you know what you're doing with electronics design, I've found that leveraging an LLM to help come up with ideas, layout block diagrams, and find parts can be super useful. Integrating Digi-Key or Mouser API support for finding parts pricing and inventory is also super handy. Using the distributor APIs can also allow you to perform natural language search which isn't possible (or isn't easy) through the distributor websites as the LLM can quickly download the datasheet and read it as part of its searching operation to verify if a part should be considered given your requirements.

> If most people have live pricing, most people have an incentive to act on price changes

It's not latency free to act on price changes. If they spike while people are asleep, what do you expect would happen? And would people get a notification everytime the price changed at all. The logistics are hard.

bradfa · 23 days ago
Some solar inverter systems already have a data connection to get live pricing information from the grid operator. It’s not that big of a problem to implement, although it definitely isn’t pervasive yet.

Minute by minute pricing is not crazy to expect and integration with HVAC, battery systems, and inverters isn’t crazy to expect to occur.

Agreed. I was kind of surprised to see 54 VDC mentioned. I am assuming this is low enough to meet some threshold for some kind of safety regulation. In other words, it doesn't shock you just 220 VAC would. I'm not entirely convinced of that however as it turns out bus bars are really dangerous in general. A 54 VDC bus bar won't shock you, but if you drop even a paperclip between the bus bar and a metal part that is grounded it basically disappears instantly in a small blast of plasma. The injury from that can be far worse than any shock you'd receive.
bradfa · 25 days ago
My experience has been that SELV (safety extra low voltage, less than 60V peak and less than 240VA) is considered safe and anything exceeding that needs certain levels of protection.

But bus bars generally should be protected regardless of voltage as they carry currents from high current capacity sources so even a lower voltage can be a safety concern.

Many server power supplies can take AC or DC input, with the DC input in the 300-500V range as this is comparable to the boost voltage for the AC power factor correction circuit. I just assumed most data centers using DC would be distributing around 400V within each rack.
