Re:Show HN: Mira, AI Walking Tours on Sunday October 11, 2026 @01:04PM (#50045347)
When I visit a new city, I love to book a walking tour with a local. Last year, I found myself with a few hours to kill in Vienna and could not book something. So I wandered around with Google Maps (what’s that?) and ChatGPT audio (tell me about it) and it was a good experience.

I built an app that automated that and have used it on several trips. Recently, I put it on the app stores and also made this street view driver. You can wander around or take pre-created tours. If you auth as a human, you can chat to create your own custom tour.

The effect of this is that it is encouraging longer agent threads. All of the previous models across major providers had a 10% cache read cost (vs normal cost) and not this is 5%

So longer threads get cheaper and one-shots stay the same price.

Re:GLM Built Its Own Inference Infrastructure on Thursday September 17, 2026 @02:01PM (#49744344)
We have been running a lot of agentic benchmarks with the various loops and tool calls on longer threads - we routinely see 90%+

Just checking now: recent runs tau3[1] was at 96% and toolathlon[2] was at 90%

Re:Pion, an agent designed to run any company autonomously on Tuesday September 15, 2026 @08:20PM (#49720618)
I've been spending all my time recently thinking about LLM costs. From that, I am currently of the mind that the most interesting question is if they can get it to work in the first place. After that, like with "performance" in the past, I believe there are ways to optimize things. We see the code harnesses doing this out of necessity, for example.

Some of the tools we use: https://www.induction.ai/docs/context-management

A blast from the past. When Taskrabbit was acquired by IKEA, I built several tools that went through the whole catalog via various crawling approaches. One tool was to estimate how long it would be to put each item together for an initial training set.

I am excited about the Rails defaults where background and cache and sockets are all database driven. For normal-sized projects that still need those things, it's a huge win in simplicity.
Re:Ask HN: Who is hiring? (March 2025) on Monday March 03, 2025 @10:52PM (#43250075)
Ario | Onsite in Palo Alto, CA | Full-time | heyario.com

I recently started at Ario where we are building an app for parents that uses AI to make things easier. We are targeting saving them one hour every day. Previously, I co-founded Taskrabbit. That was somewhat similar but now it's time to get LLMs in on the action! It's in the app store, but still early in the game, so we are looking for engineers to build it out. We are using Python and React Native.

To learn more: brian at heyario.com

We have to work on the scaling. There is lots of web scraping and LLM calls that we need to make sure works under load. I'm sure there will be quality improvements as well.
AMA: I was on the team that built the AI Assist functionality. Happy to chat about it. I became obsessed with documentation sites for a while there.

Show HN: Airbyte 1.0, Marketplace, AI Assist, GenAI Support and Enterprise GA

Hi HN friends!We can hardly believe it’s been almost four years since our original HN launch (https://news.ycombinator.com/item?id=25917403). What started as a small project has grown way beyond what we imagined, with over 170,000 deployments and 7,000 companies using Airbyte daily.When we started Airbyte, our mission was simple (though not easy): to solve data movement once and for all. Today...

Just came to say, I still think this is the best balance between the many factors of running a dev team. I keep trying to recreate it in every tool I use.
Re:ELTP: Extending ELT for Modern AI and Analytics on Tuesday November 07, 2023 @12:59PM (#38180383)
Airbyte acquired our Reverse ETL company, Grouparoo, 1.5 years ago. There is so much to solve making just the Extract and Load work well and so much value that comes from that, we have been busy there. I'm excited to circle back to publishing next year.

I like how the article notes that the stuff we were talking about with Reverse ETL (mostly activating your data in SaaS systems like Salesforce, Zendesk, etc) is one important part of Publishing. But we are also seeing traditional use cases like file uploads and new fancy stuff like vector databases.

Re:IKEA’s knowledge graph and why it has three layers on Thursday September 08, 2022 @01:02PM (#32768389)
Maybe some day this will be available in JSON.

I built a system for TaskRabbit that scraped all the IKEA products from a variety of sources and ran algorithms to determine their category and predict how long they would take to be assembled. Then there was a Mechanical Turk sort of system for human input. When combined with real-world feedback from the Taskers, it was pretty good.

For better or worse, I've personally been through the entire catalog multiple times.

Re:Airbyte acquires Grouparoo to accelerate Data Movement on Thursday April 07, 2022 @05:02PM (#30950311)
From the Grouparoo team, we are so excited to be working with Airbyte to be able to move data anywhere you want it to go.
Congrats to the Castled team on the launch.

At Grouparoo, this is a primary use case. We have a UI that engineers use locally. This helps gets things right. It outputs a JSON configuration that is checked in. When that is deployed, it does all the syncing.

It's hard to leave the comparisons dangling, for sure. But I'll defer for now. Congrats on the launch :-)
There are probably some nuances one level down. Things our users have told us they can do in these areas that, to my knowledge, Hightouch doesn't do:

* Combine data from different sources to define a model. We'v seen using Postgres as a source of truth and supplementing with Snowflake data, for example.

* Add tags to contacts in mailchimp, zendesk or make lists of them in customer.io, Pardot, etc based on segmentation. I believe Hightouch Audiences is more like a filter.

* Full workflow with branches, PRs, test suite in a repo. I saw Hightouch added git syncing to a known branch yesterday and it looks cool, but it's not the full workflow yet.

I'm certainly trying to keep it in the friendly-competition area, especially on this thread :-)

Congrats on the launch! Hightouch looks great and this need is real. Things seem to be going well, so I don't think I'm taking too much away by mentioning that we have been been working on Grouparoo, an open source alternative that solves similar pain points.

A few differences: git developer workflow focused (branches, CI, PRs, etc), ability to self host, segmentation in destinations (tagging people in mailchimp based on rules, for example)

We just finished up the Open Source Data Stack conference, which is all about this topic. Feel free to check out the reply.

Specifically, open source approaches to the modern data stack where the trend is picking the right tools for the job that revolve around the warehouse central data store.

The pieces discussed were around getting data in (Snowplow events, Meltano ELT), transforming it (dbt), reporting (Superset), getting it back into tools (Grouparoo Reverse ETL), and orchestrating things (Dagster).

We are super excited to share our new developer tooling that makes these integrations so easy. Let me know if you have any questions
Re:Slidev – Presentation Slides for Developers on Wednesday May 05, 2021 @08:00PM (#27057479)
Here was my attempt several years ago that used reveal.js

https://github.com/bleonard/jekyll-slides

I found it useful to have notes as well that showed up when presenting on the other screen.

It's certainly not production situation, but I quickly made this [1] a while back to help with "watching" certain queries for debugging. It uses a polling approach.
