<p>The user cares about the distribution of outputs.  That distribution is structurally determined by the distribution of inputs (i.e. prompts), the weights of the model, and (these days) the dynamics of the harness guiding successive generations.<p>The only way to characterize whether a choice is 'right' is to characterize the output distribution (i.e. evals)!  Changing the underlying weights necessarily invalidates whatever characterization may have been done.  One may assert that one's harness regularizes outputs back toward the desirable distribution, or one may hope the different weights induce a sufficiently similar output distribution.<p>But no, one should not be completely agnostic to the choice of weights just because there's some nondeterminism.</p>

<p>They made the coding plan a bit better toward the end, but it was pretty tough to use throughout.<p>Seems like an Amdahl’s law of inference economics?  there’s so much compute relative to SRAM on the chip and shoreline bandwidth onto the chip that caching buys ~nothing? The contended resource is SRAM and a given token of context needs just as much as another.</p>

<p>Of course there's some trim that has to go into the grinder, but we could do a much better, more respectful job of using the animal as it was instead of homogenized lumps of 80/20 or 90/10. More beef cheek in the butcher case and homemade cabeza, more lengua, more shank and round and plate, more heart and tripe and liver, etc etc etc.  Buy a subprimal and grind your burgers at home from a single animal.<p>This is more a culinary and ethical argument than efficiency or safety.  One should use the whole animal, in all its varieties, because they're delicious.  Grinding otherwise edible parts  of an animal killed on one's behalf because one disfavors (or is repulsed by) them seems to me much worse than the killing.  Eat - and enjoy! - all of it or don't kill it.</p>

<p>The operative part of schoolwork is … not the work part?  Of course school work is bullshit, in the sense that the teacher already knows what 7x9 is or who fought at Waterloo or whatever. The point is not the work product, it’s that the student produced it and has been incrementally improved by the experience!</p>

<p>And the tests. Oh god the tests. Personal recent favorite: I asked for some changes to a Dockerfile, which it did ably, and then promptly tested by writing a pytest module that traversed up to the root, read the Dockerfile, and checked that the added lines were present.</p>

<p>A big differentiator is whether one imagines an LLM in-band with most/all future software. If there is, and we’re deferring until very late parts of a program that world have been load bearing, and we’re able to programmatically ands reliably squint and say “eh i know what you meant” … then yeah formalizations seem superfluous-to-counterproductive.<p>OTOH if LLMs are to write, but not supplant, much of software, then boundaries, delegation to deterministic layers, good compilers to bonk miscreant models on the head with error message seem essential.<p>At one point it would have been shocking to assert that the compiler would live in-band with the program too. and yet JS eats the world. It seems shocking today that we could have a universal prior over the world operating in the ms/us nJ/pJ range required. And yet … ?</p>
