We’re building AI Angels, a personalized conversational AI platform with contextual memory and multimodal generation.

This week we hit an all-time high in daily active users, which pushed our infrastructure harder than expected and surfaced several scaling challenges.

Some of the areas we’ve been working through:

Managing inference spikes during peak hours

Memory persistence without excessive token growth

Conversation summarization vs full-context replay

Session concurrency limits

Moderation pipelines at scale

Subscription + payment load handling

One of the more interesting problems has been balancing persistent conversational memory with latency and cost efficiency. We’re currently experimenting with hybrid approaches (short-term context window + structured long-term memory storage).

For those running AI-first SaaS products:

How are you handling long-term conversational memory?

Are you using vector DBs for user history or structured state storage?

How are you compressing conversation history efficiently?

Any best practices for inference cost optimization at higher concurrency?

Happy to share more technical details if useful.

> It never seemed to me to be an disagreement about the four freedoms.

Who's even discussing the four freedoms today, even in the context of events like this, much less argue and agree or disagree about it? The entire point of my 'essay' was to remind everyone that those very relevant messages were deliberately deemphasized and drowned out. Arguing 'both sides were at fault' will only prolong our misery forever.

While I get the feeling you appreciate the, erhm, efficiency with which Apple modified this product, the problem is that Apple is not supposed to be efficient. They don't need to save money on the engineering process because they are not hurting for money. They sell themselves as being a design-forward company that prides itself on making bold, not expedient, choices. To take a shortcut like that shows a lack of respect for the customer to whom they are charging premium prices for these items.

As mentioned, Windows 95 uses more or less the same window decorations as NeXTSTEP - although with different semantics. What is minimize in NeXTSTEP is maximize in Windows 95 IIRC.

It could be coincidence of course, but...

> my favourite example to point to is how eerily-similar the Eurofighter Typhoon, Saab Gripen, and Dassault Rafale all look - even entirely indistinguishable at an air-show in-person - despite having zero shared pedigree

Considering that France/Dassault was initially part of the Eurofighter / European Fighter Aircraft (EFA) project, I'm not sure if that's the best example to make your point.

(I'm not a lawyer, but) I don't see the ambiguity. It's a normal grammatical sentence if parsed this way:

The Department of War may use the AI System for all lawful purposes, consistent with

- applicable law

- operational requirements

- and well established safety and oversight protocols.

Whereas if I try to parse it as a list of 4 items, it's not grammatical:

The Department of War may use the AI System

- for all lawful purposes

- consistent with applicable law

- operational requirements

- and well-established safety and oversight protocols.

> the irony it comes from the same people who blame Israel for not letting supplies into Gaza during war.

Israel did in fact do that. In fact there were several months of Israel not allowing any food or supplies whatsoever into Gaza. That was about a year ago. (It's possible Israel may have been supplying rival groups unfriendly to Hamas with food/supplies/weapons in secret, but all regular humanitarian aid was shut off.)

The gap is narrowing every day. I would come close to saying this isn’t true anymore.

For example, the ASUS TUF A14 is only one hour shorter on the real world office productivity test than the M5 MacBook Pro:

https://youtu.be/3Q837Uclwp8

(Battery life section)

It also lasts longer than the M4 Pro MacBook Pro 14”.

Bonus points: it has replaceable, upgradable, DUAL full size SSD slots and replaceable WiFi card.

You’re also getting a better discrete graphics chip that you can use for higher performance applications, or go on still-good integrated graphics to get that great battery life.

Intel Panther Lake systems are rolling out and they have graphics performance on par with the M5 MacBook Pro along with excellent power efficiency.

I took the plunge recently and got off Mac. I was pleasantly surprised that, yes, other hardware is fine. Much of it is good, actually.

There are even PC laptops with haptic trackpads, but also, you really don’t need that. macOS has made itself require it by designing around it unnecessarily, presumably to sell more $150 external trackpads (e.g., a three finger swipe is really not easier to accomplish than a keyboard shortcut, it’s just overengineering).

Even if you can’t get the same battery life…that’s something a $50 external battery can solve, and I would suggest that anything above ~8 hours of battery is more of a nice to have than a necessity.

Is it 100% as good in every respect? No. But if you’d rather use Linux and the hardware is the only thing in your way, I’d start actually looking at other laptops to find one that works for you rather than assuming MacBooks as the best.

Because the trends are bullshit and nutrition is just not that complicated.

The trends are a strange type of nutrition entertainment for people to read and then ignore in practice. There is some kind of psychological comfort in the knowing you can switch to oatmeal next week while gorging yourself at the Cheesecake Factory.

Oatmeal is good for you. News at a 11. We have known this for at least that last 50 years.

What benefit does numpy or dataframes bring to decision tree logic over what is available in Guile already ? Honest question.

Guile like languages are very well suited for decision trees, because manipulating and operating on trees is it's mother tongue. Only thing that would be a bit more work would be to compile the decision tree into machine code. Then one doesn't have traverse a runtime structure, the former being more efficient.

BTW take a look at Lush, you might like it.

I rather switch it to nowhere. But local.
I am not completely sure about the details, but I am leaning heavily, and investigating into this direction. With chat and agentic tools there plenty, accessing multiple models, and everything is evolving fast (extinct and come into existence) better keep ourselves flexible, not tied to any of the solutions. Especially not storing data in accounts. The fate of those is uncertain.

You're missing the point.

Karpathy has other projects, e.g. : https://github.com/karpathy/nanochat

You can train a model with GPT-2 level of capability for $20-$100.

But, guess what, that's exactly what thousands of AI researchers have been doing for the past 5+ years. They've been training smallish models. And while these smallish models might be good for classification and whatnot, people strongly prefer big-ass frontier models for code generation.

As an outside observer, I'd say it's by far not as bad as in Russia yet but they're heading towards a similar model. Due process has already been eroded, prosecution is more selective than ever, there are attempts to criminalize harmless minorities, a large government-controlled police force arrests anyone they want to (including journalists), government-critical press is bought, sued, and intimidated, Congress is held in contempt, court orders are ignored, and the FBI works directly on behalf of the president. That being said, they've still got a long way to go.

> For me, the butterfly keyboard was Apple's mostest worstest user interface design decision.

I really liked the butterfly kb. It was responsive, and you could hit the key cap anywhere and it would register.*

Subsequent mac book keyboards imo are all terrible and suffer from the terrible issue of sponge-ness that means i can literally press a key cap in a slightly off centre location and it Does Not Register. Its like the key movement is separate from the actuation. I have way more mis key and missing letter using later post butterfly kbs than i ever did. The worst part is this is ‘normal’ and not a fault. You just have to press harder and in the centre.

* except when it was in for work i had 3x top case replaced on my old mbp

Just going to echo this. Been using K2.5 in opencode as a switch away from Opus because it was too expensive for the sorts of things I was playing with, and it's been great. There's definitely a bit of learning to get the hang of what sort of prompts to give it and to make sure there's enough documentation in the project for it, but it's remarkably capable once you're in the swing of it.

xixyhuang nailed it — container escape is a red herring. The real problem is that your agent holds your OAuth tokens and can do massive damage without ever leaving its sandbox.

What bugs me about the current discourse is everyone focuses on where agents run and what they can access, but almost nobody talks about reconstructing what they actually did after the fact. Aviation has black boxes. Finance has audit trails. Agent systems have... logs the agent writes about itself. That's like asking the pilot to self-report the flight recorder.

Until action logging happens outside the agent's own process, none of the sandboxing stuff matters much.
by sarkarsh | 2026-03-01 12:39:50+00:00
The debugging gap in the Shen-Tamkin study is the part that worries me. AI tools are great at generating code from a clear spec. But the skill that atrophies is recognizing when code is subtly wrong — and that's the exact skill you need most when reviewing AI output.

What works for me: write the spec in a markdown file before handing it to the agent. Predict what it'll produce before reading the output. When it surprises you, figure out why before accepting. Keeps you engaged enough to actually build mental models.

The management pressure angle in this thread is real. If your org measures velocity in lines shipped, AI tools will optimize for that metric and comprehension dies quietly.
by sarkarsh | 2026-03-01 12:40:02+00:00
The compression numbers look great but I keep wondering: does the model actually produce equivalent output with compressed context vs full context? Extending sessions from 30min to 3hrs only matters if reasoning quality holds up in hour 2.

esafak's cache economics point is underrated. With prompt caching, verbose context that gets reused is basically free. If compression breaks cache continuity you might save tokens while spending more money.

The deeper issue is that most MCP tools do SELECT * when they should return summaries with drill-down. That's a protocol design problem, not a compression problem.

Yeah, because killing murderous dictators is helpful, and it doesn't matter that much who does it. In Europe, states aren't sacred – it is the freedom of people, and when people are freed, Europeans are happy even if it includes breaking the sovereignty of some terror state. I'm not saying I like Trump, but when he kills evil dictators, I can't complain. (There was 10k+ protesters killed in Iran recently)

There is huge potential hidden in Iran; it has always had a huge influence over the region and possibly the whole world.
by sarkarsh | 2026-03-01 12:40:13+00:00
shich's point about simulator mandates is the sharpest thing in this thread. Aviation treats skill atrophy as a systemic risk with institutional solutions. Software engineering treats it as an individual discipline problem. "Just practice writing code by hand" is the equivalent of telling pilots to go fly a Cessna on weekends.

The analogy also breaks in a useful way though. Autopilot doesn't modify the aircraft. Coding agents modify the codebase, and each session changes the terrain the next session operates on. The skill you actually need isn't "can I still write code" — it's "can I reason about a codebase substantially authored by a process I didn't control." That's closer to forensic engineering than piloting.
by sarkarsh | 2026-03-01 12:40:26+00:00
9dev's OAuth token exchange approach is the most practical implementation path I've seen for this. Composite agent tokens carrying both user and application claims gives you a verifiable chain without inventing new crypto infrastructure.

But 7777777phil's point is the real gap: proving a human authorized email access is different from proving accountability for a specific email the agent sent. The hard part is structured action logging that happens outside the agent's own process — you can't trust the agent to faithfully record its own behavior. Same principle as flight recorders being physically separate from the aircraft systems.

The crypto vs enterprise debate misses the middle ground. You don't need full cryptographic attestation. Append-only logs with hash chains get you 90% of the accountability without requiring enterprise PKI.
by sarkarsh | 2026-03-01 12:40:38+00:00
The ivraatiems vs rudiksz exchange is the most telling part of this thread. Both are probably reporting their experience accurately, which means the variance in agent coding outcomes is enormous. Same model, same capabilities, wildly different results depending on the scaffolding around it.

7777777phil is right that the AGENTS.md file is the actual differentiator. But it's also a manual workaround for a real gap — there's no structured way for agents to carry context across sessions. Each session starts cold. You're hand-maintaining the agent's long-term memory in a markdown file.

The tooling around agents matters as much as the agents themselves. A model that produces excellent code but can't track what it assumed or skipped is only half a system.

I'm not American, I'm not even Trumpist so your ad-hominem falls flat. I however live in a country where the soviet propaganda was crying "fascism" every single day of the year, for 60 years, so when I see people do the same I tend to be skeptical about it.

I still don't understand why "aggressively anti-socialist" policies are fascist. Fascism is itself a branch of socialism (Mussolini was one, in France the fascist leader Jacques Doriot was one as well, for instance). Being a totalitarism, it aims at engulfing every aspect of the daily life, which means supporting socialist policies (similar to communism, another totalitarism).

Authoritarian regimes in the 30´s that were "aggressively anti-socialist" weren't fascist. Franco or Salazar are relevant examples, even thought today they would be categorized as such, since you guys seem now to have only single word left to designate populist or authoritarian regimes then don't like.

Trump lacks deeply indeed the socialist aspect of fascism; it would likely be better defined as plutocratic cesarism, even though he did not make a coup (yet).

That's not how I am reading this. Here, the reaction seems mostly that Europe doesn't want to touch this mess. Which is weird, as Iran was clearly on our list of bad countries and Israel can do nothing wrong.

Local news publishes articles of Iranians in our countries being happy, political commenters indicating it can go both ways, and not much comments from politicians.

Congrats on making it work pretty much flawlessly on mobile, it's kinda rare for terminal-themed sites. It was pretty fun to navigate around, too =)

One (I think?) bug report and one suggestion:

- bug: can't get past the 5th project on mobile, whole screen just go black and I have to reload the page.
- suggestion: maybe make cd ~ or something like that bring the user back to the actual initial state, with the login banner and stuff. Just running clear results in an empty shell, and the user has to remember to run help again.

P.S.: I ran the secret command. You son of a gun XD

P.P.S.: Two suggestions, actually: display your CV with pdfjs or something, or make an HTML version. It's annoying to have to download files.

> To overcome this problem model needs specialized training, that I don‘t think the industry knows how to approach

We already have coding tuned models i.e. Codex. We should just have language / technology specific models with a focus on recent / modern usage.

Problem with something like Java is too old -- too many variants. Make a cut off like at least above Java 8 or 17.

> you seem to suggest that The Free Market could correct our path to fascism, and that pesky human services and wanton over-regulation are what are really preventing us from reaching our final enlightened form...

Not quite. I am merely pointing out that capitalism and free markets are not the enemy and that larger, more involved governments, which the political left (to which I'd assign the author) support, are a perfect breeding ground for sleaze, corruption and nepotism. This effect btw. can be observed in all of the states in which socialism has been tried. Each and every time, without exception, citizens are fleeing from these countries into capitalist countries and it's never the other way round.

> Millions of muslims around the world viewed the Iranian theocracy as the only power in the world fighting for Islam. They are devastated.

They are devastated but they are were totally quiet on the unarmed thirty thousands+ protesters the islamist iranian regime killed in a matter of days a few weeks ago.

If people keep their mouth shut when a regime murders 30 000+ unarmed people and sends its guards into hospitals to finish the wounded and if those same people think that it's then normal to launch terror attack in the west, then maybe it's time for the west to wonder if there isn't a much bigger problem than just the iranian regime.

Personally the "won't hear, won't see, won't talk" about islamists going into hospitals to slaughter people by the thousands don't suit me.

And I'll call out the hypocrisy of those who said nothing about the evil doing of the islamist iranian regime and who now want to legitimize islamist terror attacks in the west.
AI Now Has Eyes

For years AI has been “smart” but blind.

Most workflows still require explaining context: copy-pasting logs, taking screenshots, describing what’s on screen, repeating yourself and cannot share videos!. The intelligence is there, but the interface is broken.

I’ve been experimenting with a different approach: a native desktop AI (https://wezzly.com) that can see what’s on your screen in real time — terminals, browsers, watches videos — so you don’t have to explain or copy-paste context. The model only acts when asked, everything runs locally, and nothing is stored and its a AI companion that lives on the computer with you with a personality.

Curious what people think:
Is continuous visual context the missing piece for AI assistants?

> I prefer assassinations of leaders in wars over deaths of soldiers and especially civilians.

To me, this argument doesn't hold water. Think about some counterexamples: (1) Netanyahu and Gaza. Surely, 100K+ civilians died as a result of that war. (2) Kennedy, Johnson, Nixon and Vietnam. A staggering number of civilians died in that war. (3) GW Bush in Afghanistan and Iraq/2.

My guess: All of those leaders are responsible for more innocent civilian deaths in each conflict than Khamenei's entire reign.

To me, I am very conflicted about the assassination of Khamenei. Yeah, he did a bunch of bad stuff and was very destabilising in the region, but I need to draw the line at assassination. It was unnecessary. It is a slippery slope.

Part of the problem is that due to a combination of the electoral college, gerrymandering, voter supression, propaganda, and Citizens United; America's government is not meaningfully democratic.

Even setting that aside, I don't think that people are saying that they want corporations to make the rules. Rather, what I think they are saying is that they don't want AI to be used for mass surveilance or autonomous weapons and cutting the DoD off at the corporate level is one way to accomplish that.

>Or will people realize they are programming and discipline up?

Or will there be coding across disciplines, and attendant theories of literacies in context?

What I like about the OP is the consonance with literate practices, which has gone through similar generations of "our children don't know how to [...]" alongside of "our children will not need to [...] because of the machines."
