<p>Is the tradeoff of the parallel output that we don't get arbitrary string generation? like output # of tokens is fixed ahead of time?<p>Either way, really cool and impressive.</p>

<p>for me, almost all of the work is specs<p>I am no longer:<p>- reading docs for hours and hours<p>- typing (barely at all)<p>- writing code<p>- manually doing tight debug loops<p>- using an IDE<p>to do this I had to give up reading or even controlling the code and focusing on behavior/design-level control (not superficial, still dictating overall technical architecture)<p>i have agents doing everything from writing the code, verifying the code, hardening, increasing test coverage, analyzing behavior, algorithmic perf improvements, managing/deploying to cloud resources, etc... (pretty much everything)<p>and I am accomplishing projects that would take months or years in a fraction of the time.<p>that's way more than 10x.<p>somehow, this is harder and more cognitively demanding than writing code</p>

<p>we need some better standard long-context benchmarks.<p>needle in a haystack is not good for this, yes it proves the model can attend to its context, but in its usual form, somewhat trivializes the query-key relationship.<p>something like long-form Q&A would be more ideal. Like reading a book and answering questions that require synthesizing information derived from either the whole thing or disparate portions of it. Like describing an entire character arc in a 1000 page novel with examples and evidential moments.</p>

<p>the qwopus 27b model is good for grunt work style tasks, even across multiple files. Piping a bunch of things through, small factoring changes, stuff that just takes time to type out.<p>I wouldn't rely on it for large stuff like codex though. I haven't tried out deepseek/kimi, if we could run those locally it would be great.</p>

<p>promote yourself to PM only and use agents for authoring, verification, tests, checking the tests<p>orchestrator -> parallel subagents with investigation, authoring, verification, benchmarking subagents and integration / final verification handled by parent has improved my productivity too.<p>I feel like from here its agent swarms against a whole spec but haven't got there yet.<p>Still getting plenty of bugs in the more complex scenarios, but mostly (in some projects) i never have to look at the code and treat it like a black box</p>

<p>I built a small standalone interactive to help make diffusion sampler steps more intuitive. It’s focused on the inference-time update: how the sampler moves from the current noised state toward a less-noisy state, one step at a time.<p>This grew out of a larger post where I try to explain diffusion models in less-dense terms, especially the parts that felt non-intuitive to me when first reading the papers. That post emphasizes that diffusion models incrementally “step” toward a solution rather than generating it all at once, and this interactive zooms in on that sampler-step idea specifically.<p>Would love feedback on:<p>- whether the interaction makes the sampler update easier to reason about<p>- what other diffusion concepts would be useful to turn into small interactives<p>Link:

<p>The classic papers describing diffusion are full of dense mathematical terms and equations.<p>For many (including myself) who haven’t stretched those particular math muscles since diff eq class a decade or so ago, the paper is just an opaque wall of literal Greek.<p>In this post I describe my personal understanding of diffusion models in less-dense terms, focusing on intuitive understanding and personal mental models I use to understand diffusion.</p>

<p>Something like a perplexity/log-likelihood measurement across a large enough number of prompts/tokens might get you the same in a statistical sense though. I expect those comparison percentages at the top are something like that.</p>

<p>Either really comprehensive tests (that you read) or read it. Usually i find you can skim most of it, but like in core sections like billing or something you gotta really review it. The models still make mistakes.</p>

<p>I'm not too sure about this take. The larger code rewrite issue is constantly trying to be solved, which is somehow making the problem worse.<p>In another view, standard libraries do a pretty good job.</p>
