Hello HN,

We’re the team behind WarpGrep. It’s a FAST context retrieval subagent designed to fix coding agents spending ~60% of their time searching for context + the huge context rot problem.

We built this because we found that standard RAG or naive context stuffing leads to "context rot"—where irrelevant files poison the model’s reasoning on long-horizon tasks. Inspired by Cognition’s SWE-Grep, we wanted to build an accessible version that integrates via MCP (Model Context Protocol) or SDK.

How it works: Instead of a single prompt trying to do everything, WarpGrep treats context retrieval as a distinct, RL-trained system. We reward correct context retrieval and penalize irrelevant lines.

Constraints: It operates on a strict budget of 4 turns. Parallelism: It executes up to 8 parallel tool calls per turn (grep, list, read, etc.).

Inference: We worked with NVIDIA to optimize this on B200s. We are hitting ~900 tokens/sec (compared to SWE-Grep’s ~650 t/s). The heavy prefill optimization was critical here because grep operations are read-heavy.

The Results: In our internal benchmarks, offloading retrieval to this subagent speeds up tasks by 40% and reduces token usage by roughly the same amount. More importantly, it seems to reduce "context rot" by ~70% on longer tasks because the agent isn't distracted by irrelevant file headers. On SWE-Bench Pro we see 5-12% improvement on long horizon tasks and stable chats for 2-3x more user messages.

It works with every coding agent - Claude Code, Codex, and OpenCode. We’re curious to see how it handles your edge cases (especially huge repos).

There is a free tier, but if you want to push it hard, you can use the code BF16 for 40M tokens of credit to test the API limits. We do recommend adding a payment method to get around the rate limits but you won't be charged until December 14th. At which point it will still be almost 10x cheaper than Claude Haiku.

Happy to answer questions about the CUDA optimizations or the RL training process!

> For all that tools like PeerTube, Mastodon, etc are clunkier and more limited than things like YouTube, Bluesky, etc, I think that argument is increasingly going to be irrelevant to their value

Their value is going to stay limited if people don't want to actually use them.

Technically proficient people may overlook something being clunky if it suits their needs in other ways, but it's a harder sell for the average user. And really, it shouldn't be an issue. Good UX isn't trivial, but it's not especially complicated or budget-busting either.

Maybe.

Given the existence of the universal weight subspace (https://news.ycombinator.com/item?id=46199623) it seems like the door is open for cases where an emergent intelligence doesn't map vectors to the same meanings that we do. A large enough intelligence-compatible substrate might support thoughts of a surprisingly alien nature.

(7263748, 83, 928) might correspond with "hippopotamuses are large" to us while meaning something different to the intelligence. It might not be able to communicate with us or even know we exist. People running around shutting off servers might feel to it like a headache.

Honest question - do you think that everyone else thinks this is even REMOTELY what the front page will look like in 10 years?

I comment because I really cannot figure out why you left your comment. Do you think the rest of the commenters think this has predicted the future? It might be one thing to point out specific trends you think will not play out, or unexpected trends you think may show up that are currently left out. But to just remark that the future will contain things we cannot currently predict seems so inherently, unspokenly obvious that I just have to assume that wasn't the point of your post, and I've missed it entirely.

Sorry, I'm really not trying to be mean or anything - i'm just really confused.

No, it means you have something unique to say.

The bar is there, but it is lower than you expect. If you have a truly unique point of view to express, that brings some value to the table, slots will open up.

And I've spoken at plenty of conferences. :) Not always in the glamour rooms/slots. But... I did have one talk fill a room out the door. That was a talk on a difficult/controversial topic, and by then... I was probably about as expert as they came on the issue.

I didn't start with that though. I just started with a simple point of view talk. And I'd argue the second version of that talk is still one of the best I've given in my life.

That's a selective list. High RAM Macs are available. MBPro goes up to 128GB. Mac Studio goes up to 512GB. Not cheap, but available.

I wonder if a new tech company was founded with a quality-first and customer-service mentality, could they succeed? Especially if there are NO investors trying to make a quick buck.

Certainly the company would provide good jobs, good benefits, salary and bonuses.

But none of this "the company is the product".

MBAs would be strictly forbidden.

Author here.

Thanks for all the feedback! To address some of the key points in the comments:

1. Completely agree learning the fundamentals is important. I did mention groking the underlying CompSci in the article.

2. The market has generally decided that an AI Engineer is an engineer who is proficient at applying AI in the products they create – not somebody who uses AI to create the products. This article used the former as its example, not the latter.

3. Completely agree that an engineer in the upper right quadrant could just as well be a fundraiser and founder, too. If that's what they want, more power to them. In any event, I love creating a culture on my teams that gets engineers routinely thinking like customer-centric founders. Which brings us to...

4. I don't view prioritizing new technologies as hype-chasing. There's an enormous amount of EQ required to understand which technologies are likely to be a net positive vs. negative to a marketplace and the customers that comprise it over the long-term, hence the point about customer-centricity. 20-30 years ago, I was all in on dyanmic web technologies but wasn't investing time or energy into Flash or Java applets. I was, generally speaking, never a proponent of NoSQL or microservice architectures, but did love iterative improvements to SQL databases and the advent of cloud-native platforms. For the past few years, I've been all in on LLMs but never bothered to dabble in blockchain, Web3, NFTs, or the metaverse. There's a reason for all of this contrast, and it's grounded in focusing on what actually drives outcomes for customers, not just what's trending. It comes down to making intelligent bets on the future.

Cheers!

Do you mean that this is technically possible, or that this is a feature that will be supported? I've preordered the Time 2, so having the ability to configure it that way to significantly extend the battery life of the ring could be interesting. On the other hand, using it standalone might be fine for me. I wouldn't really know how fast I might go through the battery without using it for a while.

I find myself designing a TRPG (Final Fantasy Tactics, Disgaea) with Grandia time & space mechanics in my head; take position even a bit more seriously than Grandia did, but build on a TRPG balance and skill structure. Basically end up with a much more dynamic take on the TRPG, which has always been a bit of a static experience. The canceling mechanics coming from Grandia would be banger in that sort of more dynamic TRPG.

There is, of course, a lot of games all around that space but I don't know of anything that quite matches what I'm laying out here.

(Although the cancellation mechanics would need some careful attention. It allows for a whole bunch of weak characters to keep a single strong character down by always cancelling what they're doing. I suppose just turning it into a skill check itself instead of being 100% as it is in Grandia would do the trick, though.)

I think I've seen one or two, and only because I noticed them as a weird callout in a $LARGE_FINANCE_INSTITUTION infosec bingo sheet. Of course I had to check that they really were running with OV certs.

Some of the outfits in that space will be heavily hit by the shortening certificate max-lifetimes, and I do hope that the insurance companies at some point also stop demanding a cert rotation before 90 days to expiry. It's a weird feeling to redline a corporate insurance policy when their standard requirements are 15 years out of date.

We use AI heavily in our product and development flow. Sometimes we'd encounter a problem none of us can figure out at the moment so some of us would use ChatGPT to brainstorm some solutions. We'd present the solutions, poke holes into them, and go forward from there. Sometimes we don't use the actual ideas from GPT but ideas that were inspired by the generated ideas.

The intent isn't to shift accountability, it's to brainstorm. A shitty idea gets shot down quickly, whereas a good idea gets implemented.

> If there are enough vacant units available and enough supply that property values are not appreciating like crazy, someone will crack and cut the rent or sell out so they can get a better return on their money.

Your thesis here is disproven in large cities like the one I live in, Miami. Many investors / property owners here don't give a damn on getting a return on their investment so long as it doesn't go to $0 - they buy real estate sight unseen because it's a good way for the well-to-do in LatAm and Russia to get their money out of developing/regressing economies and into the USA. Half the units in the building I live in are vacant - they are owned by Brazilians, Argentines, Venezuelans, etc who want a safe haven for their money (and for Brazilians, as a base to buy loads of Apple products that they can turn around and sell back in Brazil for a 2-3x markup).

took me a little over a month to do all this from scratch. made over 500 individual sites / components / different variations of sites / different stacks / I tried a lot of stuff

and this combo is the most capable, static anything I have ever built since I got github co pilot pro plus which lets me use agents to code on vs code directly its amazing and im making more things of course.

Hosted on github because its free and I made it possible so you can download the repository and plug and play for your own git hub pages

looking for any feedback if anyone has any ideas!

- goal was to showcase the capability of the different models quality of code production

- how much time coding vs cleanup vs babysitting

- Gemini 3 is legit crazy and the new base line for everything

- I attempted to code this like a full web app not sure if that part of it is 100% but it does look really good on mobile works great

Very cool.

It's all about that 80-bit/82-bit floating point format with the explicit mantissa bit just to be extra different. ;) Not only is it a 1:15:1:63, it's (2(tag)):1:15:1:63, whereas binary64 is 1:11:0:52. (sign:exponent [biased]:explicit leading mantissa bit stored?:manitissa remaining)

Other pre-P5 ISA idiosyncrasies: Only the 8087 has FDISI/FNDISI, FENI/FNENI. Only the plain 287 has a functional FSETPM. Most everything else looks like a 387 ISA-wise, more or less until MMX arrived. That's all I know.

I'm curious what the CX-83D87 and Weiteks look like.

Keep up the good work!

PS: Perhaps sometime in the (near) future we might get almost 1:1 silicon "OCR" transcription of die scans to FPGA RTL with bugs and all?

Actually neither - you were suggesting that money makes the problem valid. It doesn't. You can charge all you want - it either becomes useless (why are we trying to find ways to get more profit to hospitals???) or it reduces the staff who are better suited to go somewhere else.

This is an unbelievably inefficient way to try and move money to those who need it. The market correction should be elsewhere.

On the landing page I see full names and pictures of customers but not any information about the founders and/or shareholders. I click on "about us" and "privacy" and "terms" and "trust center" and I cannot figure out: What is the name of the company, where is it located, who will be having access to my data. For a security-related startup if such information is missing it's a big red flag.

Also unfortunately the animation on the landing page makes the whole website quite slow.

The measurements you are linking to are showing the level of distortion (HD3 v level) not dynamic range! The Y-axis on the graphs is showing the 3rd harmonic in dB in relation to the mV given in on the x-axis. This has absolutely nothing to do with dynamic range and it is also not the signal-to-noise-ratio. The fundamental frequency in those measurements was at 315 Hz. HD3 refers to Harmonic Distortion at 3rd level.

You seem very confused about what I'm saying so I will try again, despite your insult.

It is extremely clear why he would be against a closed source thing regardless of what it is. That is not in any sort of a doubt.

He however is arguing about whether it knows and understands things.

When you said "debating the epistemology of closed-source flagship models is fruitless" I understood you to be talking about this, not whether closed source things are good or not. Otherwise what did you mean by epistemology?

> Feel free to check out a longer analysis [1] (which he also linked in the source).

Yes, I quoted it to you already.

> You're not making an argument. How, directly and in plain language, is his opinion incorrect?

They are AI systems by long standing use of the term within the field.

> Yes...

So we have a test for it?

> it is one of very few foundational principles and the closest thing to a universally agreed idea. Are you actually trying to challenge 'cogito ergo sum'?

That is not a test.

I'm also not sure why you included the words "to exceptionally simpler systems" after snipping out another part, that doesn't make a sentence that works at all and doesn't represent what I said there.

From hosting a peertube instance solely for my own stuff for several years, I've come to appreciate just how difficult self hosting a streaming video platform is. As you say, bandwidth and storage requirements are significant; another less obvious one is transcoding. When a user uploads an HD video file, it needs to be transcoded into lower resolutions if you want there to be a hope of people streaming it. While Peertube itself is perfectly happy running on 2-4 vcpu cores on a cheap cloud vm, if you use those cores to handle transcode jobs it can take huge amounts of time (like 20+ hours) to transcode even medium length 1080p videos. So you really need either a lot of CPU that sits mostly idle, or hardware acceleration, both of which are expensive when purchased from cloud providers. Or you can use remote transcoding to offload transcode jobs onto your home gaming pc or whatever, which works well, but can be complicated and a bit touchy to set up properly, and now you have a point of failure dependent on your home network...

And then, people watching videos are used to the YouTube experience with its world class CDN infra enabling subsecond first frame latencies even for 4k videos. They go on Peertube and first frame takes like 5 seconds for a 1080p video...realistically, with today's attention spans most of them are going to bounce before it ever plays.

I worked backwards from Starcraft, and to my mind WC2 still feels a bit archaic, insofar as the two races feel nearly identical. WC3 did a better job of differentiating the Human and Orc units, and then of course added Dark Elves and the Undead to the mix, too.

But I will say that WC2 is the last major RTS I can think of with naval combat. After Starcraft streamlined it to be land and air only, it seems the entire industry followed suit. Even WC3 didn't bother bringing ships back, to my memory.

There are a wide number of small problems for which we do not need bridges.

As a stupid example, I hate the functionality that YouTube has to maintain playlists. However, I don't have the time to build something by hand. It turns out that the general case is hard, but the "for me" case is vibe codable. (Yes, I could code it myself. No, I'm not going to spend the time to do so.)

Or, using the Jira API to extract the statistics I need instead of spending a Thursday night away from the family or pushing out other work.

Or, any number of tools that are within my capabilities but not within my time budget. And there's more potential software that fits this bill than software that needs to be bridge-stable.

I don't believe this was written by Gemini, at least with that prompt, because it is obvious (hilarious and creative) satire of HN and the tech industry based on inside HN jokes and tropes, and clearly isn't a literal interpretation of the prompt.

Moreover, a quick look at your profile suggests these jokes are pretty inline with your sense of humor and writing style.

Anyways, if I'm correct, it's especially hilarious and impressive.

Of course I know how market forces work. They are not the only forces we can manage. They are not the only levers we can pull. Economics are cool, but not almighty. There is no scenario in which a hospital gets extra profit, and turns around and simply reduces the cost for those in need. No - no additional resources are being removed. That's not how hospitals work.

You know I would be happy to offer this service to investors for a mere tens of millions of dollars. I'll send you photos of our weekly money bonfire, built with your money, and when you're tired of pictures of your money on fire, I'll simply... stop.

Heck, in accordance with the several zeitgeists of our age, I'll even do you the solid of fraudulently generating the money-on-fire pictures with AI, so when you get tired of seeing your money on fire I'll even hand, say, 25% of it back to you, as the result of my tireless efforts to bring value to my shareholders. That's a better return than you'll get from most of these investments!

Sometime in the 80s, I implemented the core of the Mandelbrot Set calculation using assembly on an 8087. As the article mentions, the compilers did math very inefficiently on this stack architecture. For example, if you multiplied two numbers together and then added a third, they would push the first two numbers, multiply, pop the result, push the result back onto the stack (perhaps clearing the stack? after 40 years I don't remember), push the third number, add, pop the result. For the Mandelbrot loop this was even worse, as it never kept the results of the loop. My assembly kept all the intermediate results on the stack for a 100x speed up.

Running this code, the 8087 emitted a high-pitched whine. I could tell when my code was broken and it had gone into an infinite loop by the sound. Which was convenient because, of course, there was no debugger.

Thanks for bringing back this memory.

I'm not sure that I'm more surprised that it's only been 10 years or that it's been that long. I mean, that's a relatively quick turn around to pretty much dominate TLS certs to the point that it's the default for so many platforms... that HTTPS has become such a norm over the exception.

On the other hand, has it really been that long, it seems just yesterday I was first trying to configure nginx for it. That said, since I discovered Caddy, I haven't really looked back, though I do use Traefik too.

I mean, by comparison, it feels like IE6 took longer to die than Let's Encrypt has been around.

Unless this authority has some ownership over the term and can prevent its misuse (e.g. with lawsuits or similar), it is not actually the authority of the term, and people will continue to use it how they see fit.

Indeed, I am not part of a movement (nor would I want to be) which focuses more on what words are used rather than what actions are taken.

They could be more general, sure, but this is all extremely far from his bar for classifying things as AI.

> To give a concrete and simple example, take a simple network trained to recognized digits. The network can be of arbitrary quality, it can be robust or not, fast or slow, but it can't do more than digits.

This is the kind of thing he would class as AI, but not LLMs.

I'm trying to be as civil as I can, but apps like this should be treated as literal scams. AI detection doesn't and cannot work unless it looks for intentional watermarks left by llms. You are preying on people without domain knowledge.

On the off-chance this one does something different, I tested it on several pre-ai pieces of text - they were all marked as AI, including the declaration of independence which scored 91.35% AI-generated.

Does your friend have anything to corroborate this claim? Perhaps the email with identifying details censored?

I have a received an occasional email mentioning donations. They are extremely infrequent and never ask me for a specific amount. I would be incredibly surprised to see evidence of "hounding" and requests for $50,000.
