alach11··on Gemini 3 Flash: Frontier intelligence built for speed
I really wish these models were available via AWS or Azure. I understand strategically that this might not make sense for Google, but at a non-software-focused F500 company it would sure make it a lot easier to use Gemini.
alach11··on Advent of Code 2025
Usually the first day or two are readily solvable in Excel with just regular spreadsheet formulas.
alach11··on Claude Opus 4.5
This is the biggest news of the announcement. Prior Opus models were strong, but the cost was a big limiter of usage. This price point still makes it a "premium" option, but isn't prohibitive.

Also increasingly it's becoming important to look at token usage rather than just token cost. They say Opus 4.5 (with high reasoning) used 50% fewer tokens than Sonnet 4.5. So you get a higher score on SWE-bench verified, you pay more per token, but you use fewer tokens and overall pay less!

alach11··on Olmo 3: Charting a path through the model flow to lead open-source AI
Just curious - are you using Open WebUI or Librechat as a local frontend or are all your workflows just calling the models directly without UI?
alach11··on Gemini 3
This is a really impressive release. It's probably the biggest lead we've seen from a model since the release of GPT-4. Seems likely that OpenAI rushed out GPT-5.1 to beat the Gemini 3 release, knowing that their model would underperform it.
alach11··on Disrupting the first reported AI-orchestrated cyber espionage campaign
"Quantity has a quality all its own". It's categorically different to be able to do harm cheaply at scale vs. doing it at great cost/effort.
alach11··on You should write an agent
Can you cite your source for inference being at a loss? This disagrees with most of what I've read.
alach11··on Claude Code refused to add rainbows and unicorns to my app
This is almost certainly the issue. It's very unintuitive for users, but LLMs behave much better when you clear the context often. I run /clear every third message or so with Claude Code to avoid context rot. Anthropic describes this a bit with their best practices guide [0].

alach11··on Gemini 2.5 Computer Use model
Computer use is the most important AI benchmark to watch if you're trying to forecast labor-market impact. You're right, there are much more effective ways for ML/AI systems to accomplish tasks on the computer. But they all have to be hand-crafted for each task. Solving the general case is more scalable.
alach11··on Claude Sonnet 4.5
I'm really interested in the progress on computer use. These are the benchmarks to watch if you want to forecast economic disruption, IMO. Mastery of computer use takes us out of the paradigm of task-specific integrations with AI to a more generic interface that's way more scalable.
alach11··on Instant Checkout and the Agentic Commerce Protocol
Thus far I didn't have to worry about ChatGPT having bad incentives when giving me advice on product purchases. Now that "Merchants pay a small fee on completed purchases", will the model steer me towards ACP-supported retailers at a higher rate?
alach11··on California issues fine over lawyer's ChatGPT fabrications
> using AI is clearly doing more harm than good

How do you know this? Wouldn't we expect the benefits of AI in the legal industry to be way less likely to make the front page of HN?

alach11··on On It, Boss
I can't fathom why Microsoft has such limited functionality in Copilot for Excel. Some of the ideas in projects like this (and similar) seem so obvious. Are they just being conservative with token cost?
alach11··on Ask HN: What's a good 3D Printer for sub $1000?
I'm going to make an unpopular suggestion. Have you considered using a service that will print and ship to you, like CraftCloud?

Depending on volume, your total cost would likely be lower. I know you mentioned privacy concerns so this may not be an option. But it significantly simplifies your work, letting you focus on the parts themselves.

alach11··on New Mexico is first state in US to offer universal child care
> Florida did drug testing as a condition for welfare benefits... and it cost more than they saved

It's more complicated than that. Of the 6352 people who applied for TANF, 2306 dropped out during the process. Then of the 4046 TANF applicants remaining, only 2.6% tested positive for drugs. The vast majority of media coverage focused on the 2.6% being less than the ~8% drug-use rate in the general population.

What we don't know is of the people who dropped out, was this due to unintended reasons (privacy concerns, the inconvenience of the drug test, missing deadlines) or due to the intended reason (people self-selecting out because they knew they would test positive and become ineligible for 12 months). We'll never know the real breakdown, but it's misleading to say "it cost more than they saved".

alach11··on Claude for Chrome
Same with Firefox+Windows 11. I guess they really only care about Chrome...
alach11··on 95% of generative AI pilots at companies are failing – MIT report
I think you're on the right track here. Most technology pilots fail. As long as risk/investment is managed appropriately, this is healthy. This seems to follow from Surgeon's Law... 90% of everything is crap [0].

alach11··on Gemini Embedding: Powering RAG and context engineering
OpenAI did it a few weeks earlier when they released text-embedding-3-large, right?
alach11··on What would an efficient and trustworthy meeting culture look like?
Sure. But there are plenty of ways to achieve the same outcome without wasting 8 hours of time for every employee. And once you scale this across all the aspects of company policy/culture you want push, mandatory training classes become incredibly inefficient.
alach11··on What would an efficient and trustworthy meeting culture look like?
> Everyone had to take an online class (about 8 hours) about effective meetings

As soon as I read this line I grimaced. This is a clear sign of an organization that doesn't respect peoples' time. The class should be an email (and proper follow-up by the management chain) establishing three rules:

- Meetings must have an agenda

- After a meeting, there must be a follow-up email describing what was decided and any action items

- Recurring meetings should be rare/exceptional

- Given good meeting notes and action items sent afterwards, reduce the invite list to decision makers; people who need to be informed can be added to the follow-up email

alach11··on OpenAI claims gold-medal performance at IMO 2025
> it will likely generalize to all kinds of reasoning problems, not just mathematical proofs

Big if true. Setting up an RL loop for training on math problems seems significantly easier than many other reasoning domains. Much easier to verify correctness of a proof than to verify correctness (what would this even mean?) for a short story.

alach11··on ChatGPT agent: bridging research and action
It's very hard for me to imagine the current level of agents serving a useful purpose in my personal life. If I ask this to plan a date night with my wife this weekend, it needs to consult my calendar to pick the best night, pick a bar and restaurant we like (how would it know?), book a babysitter (can it learn who we use and text them on my behalf?), etc. This is a lot of stuff it has to get right, and it requires a lot of trust!

I'm excited that this capability is getting close, but I think the current level of performance mostly makes for a good demo and isn't quite something I'm ready to adopt into daily life. Also, OpenAI faces a huge uphill battle with all the integrations required to make stuff like this useful. Apple and Microsoft are in much better spots to make a truly useful agent, if they can figure out the tech.

alach11··on Chain of thought monitorability: A new and fragile opportunity for AI safety
Ironically, every paper published about monitoring chain-of-thought reduces the likelihood of this technique being effective against strong AI models.
alach11··on Pascal's Scams (2012)
A lower-key variant of this frequently comes into play with consulting or other sales pitches. "You spend <big number> per year on this <necessary business expense>. Our service will easily shave 2% off this, making the cost of our service completely negligible and this purchase an obviously good decision."
alach11··on Build and Host AI-Powered Apps with Claude – No Deployment Needed
This is starting to encroach on Lovable, right? I do suspect the effect of these "vibe coded" apps on the SaaS market will be smaller than expected. Heavier-featured apps will have all sorts of functionality and polish a user won't even think to ask Claude to build. And the amount of effort to describe everything you need an app to do is higher than it seems.

Instead, I think this is going to open a new paradigm with an immense long-tail of hyper-niche fit-for-purpose business applications. There's so much small-scale work that happens in corporations that isn't common enough to be worth building a product to solve. But it's still a big time-saving to the departments/users if they can improve the process with a vibe-coded app!

alach11··on ChatGPT's enterprise success against Copilot fuels OpenAI/Microsoft rivalry
You nailed it. Microsoft should have a huge advantage with depth of integration, but for some reason treats Copilot in office as a glorified chat iframe. It's a huge missed opportunity.
alach11··on Updates to ChatGPT for Business (internal connectors, record mode, and more) [video]
Interesting to see them announce "Record Mode", where ChatGPT can listen in on your meetings and use that to inform future conversations. I suspect the idea of an ever-present all-hearing AI is going to be a growing trend. Especially with them partnering with Jony Ive on a physical device.
alach11··on Scientists have found a way to 'tattoo' tardigrades
I'm trying to think of practical use cases for this. Is surveillance one of them? Could you drop a bunch of these marked tardigrades on an object or on money and later identify it?

Doesn't seem like a very efficient way to accomplish the goal, but it would make for a great plot line in a spy movie.

alach11··on Zuckerberg: "The average American has 3 friends, but has demand for 15"
I think this is really sick. And it's against the mission of Meta.

It's possible, despite what many of these comments say, to build friendships as an adult. It just takes investment. What has helped me the most is:

- Bringing connections from one context into another. For example if you have a colleague you like, your relationship can't grow closer unless you start hanging out in a non-work context. Get involved with athletic activities with them. Or if you have similar aged kids, invite them over for a play date while the adults hang out.

- Combining friend hangouts. If you want 15 friends but only have time to hang with people every couple days, you don't have time to meet with people one-on-one. Organize group events like dinner parties or pot lucks. Also don't restrict these events to be just "work friends" or "pickle ball friends". Cross-pollinate groups.

- Create local friends. Nothing is more convenient than friends you live next door to. We do porch wine with our neighbors on Monday nights. It takes very little effort to set up a group text and get momentum around something like this.

alach11··on Reasoning models don't always say what they think
This is basically a big dunk on OpenAI, right?

OpenAI made a big show out of hiding their reasoning traces and using them for alignment purposes [0]. Anthropic has demonstrated (via their mech interp research) that this isn't a reliable approach for alignment.
