How do I keep up with AI?

This question comes up a lot in conversations. The short answer? I don’t. There’s just too much happening, too fast, for anyone to stay on top of everything.

While I enjoy sharing links and recommendations, I realized that a blog post might be more helpful. It gives folks a single place they can bookmark, share, and come back to on their own time, rather than having to dig through message threads where things inevitably get lost.

That said, here are some sources I use to try and stay informed:

  • Newsletters are great for curated content. They highlight the top stories and help filter through the noise.
  • Blogs are often the primary sources behind those newsletters. They go deeper and often cover a broader set of topics that might not make it into curated roundups.
  • Podcasts serve a similar role. In some cases, they provide curation like newsletters and deep dives like blogs in others. Best of all, you can tune in while on the go making it a hands-free activity.

For your convenience, if any of the sources (including podcasts) I list below have RSS feeds, I’ve included them in my AI Starter Pack, which you can download and import into your favorite RSS reader (as long as it supports OPML file imports).

If you have some sources to share, send me an e-mail. I'd love to keep adding to this list! If they have a feed I can subscribe to, even better.

Newsletters

Blogs

I pride myself on being able to track down an RSS feed on just about any website, even if it’s buried or not immediately visible. Unfortunately, I haven't found a feed URL for either OpenAI or Anthropic which is annoying.

OpenAI and Anthropic, if you could do everyone a favor and drop a link, that would be great.

UPDATE: Thanks to @m2vh@mastodontech.de for sharing the OpenAI news feed.

I know I could use one of those web-page-to-RSS converters, but I'd much rather have an official link directly from the source.

Podcasts

Subscribing to feeds

Now that I’ve got you here...

Let’s talk about the best way to access all these feeds. My preferred and recommended approach is using a feed reader.

When subscribing to content on the open web, feed readers are your secret weapon.

RSS might seem like it’s dead (it’s not—yet). In fact, it’s the reason you often hear the phrase, “Wherever you get your podcasts.” But RSS goes beyond podcasts. It’s widely supported by blogs, newsletters, and even social platforms like the Fediverse (Mastodon, PeerTube, etc.) and BlueSky. It’s also how I’m able to compile my starter packs.

I've written more about RSS in Rediscovering the RSS Protocol, but the short version is this: when you build on open standards like RSS and OPML, you’re building on freedom. Freedom to use the tools that work best for you. Freedom to own your experience. And freedom to support a healthier, more independent web.

Starter Packs with OPML and RSS

One of the things I like about Bluesky is the Starter Pack feature.

In a gist, a Starter Pack is a collection of feeds.

Bluesky users can:

  • Create starter packs
  • Share starter packs
  • Subscribe to starter packs

Unfortunately, Starter Packs are limited to Bluesky.

Or are they?

As mentioned, starter packs are a collection of feeds that others can create, share, and subscribe to.

Bluesky supports RSS, which means you could organize the feeds using an OPML file that you can share with others and others can subscribe to. The benefits of this is, you can continue to keep up with activity on Bluesky from the feed reader of your choice without being required to have an account on Bluesky.

More importantly, because RSS and OPML are open standards, you're not limited to building starter packs for Bluesky. You can create, share, and subscribe to starter packs for any platform that supports RSS. That includes blogs, podcasts, forums, YouTube, Mastodon, etc. Manton seems to have something similar in mind as a means of building on open standards that make it easy for Micro.blog to interop with various platforms.

If you're interested in what that might look like in practice, check out my "starter packs" which you can subscribe to using your RSS reader of choice and the provided OPML files.

I'm still working on similar collections for Mastodon and Bluesky but the same concept applies.

Although these are just simple examples, it shows the importance of building on open standards and the open web. Doing so introduces more freedom for creators and communities.

Here are other "starter packs" you might consider subscribing to.

If this is interesting to you, Feedland might be a project worth checking out.

OPML for website feeds

While thiking about implementing .well-known for RSS feeds on my site, I had another idea. Since that uses OPML anyways, I remembered recently doing something similar for my blogroll.

The concept is the same, except instead of making my blogroll discoverable, I'm doing it for my feeds. At the end of the day, a blogroll is a collection of feeds, so it should just work for my own feeds.

The implementation ended up being:

  1. Create an OPML file for each of the feeds on by website.

     <opml version="2.0">
       <head>
     	<title>Luis Quintanilla Feeds</title>
     	<ownerId>https://www.luisquintanilla.me</ownerId>
       </head>
       <body>
     	<outline title="Blog" text="Blog" type="rss" htmlUrl="/posts/1" xmlUrl="/blog.rss" />
     	<outline title="Microblog" text="Microblog" type="rss" htmlUrl="/feed" xmlUrl="/microblog.rss" />
     	<outline title="Responses" text="Responses" type="rss" htmlUrl="/feed/responses" xmlUrl="/responses.rss" />
     	<outline title="Mastodon" text="Mastodon" type="rss" htmlUrl="/mastodon" xmlUrl="/mastodon.rss" />
     	<outline title="Bluesky" text="Bluesky" type="rss" htmlUrl="/bluesky" xmlUrl="/bluesky.rss" />
     	<outline title="YouTube" text="YouTube" type="rss" htmlUrl="/youtube" xmlUrl="/bluesky.rss" />
       </body>
     </opml>
    
  2. Add a link tag to the head element of my website.

Introducing Google Antigravity

Today, we are introducing Google Antigravity, our new agentic development platform. While the core is a familiar AI-powered IDE experience with the best of Google’s models, Antigravity is evolving the IDE towards an agent-first future with browser control capabilities, asynchronous interaction patterns, and an agent-first product form factor that together, enable agents to autonomously plan and execute complex, end-to-end software tasks.

Valve thinks Arm has ‘potential’ for SteamOS handhelds, laptops, and more

“I think that it paves the way for a bunch of different, maybe ultraportables, maybe more powerful laptops being Arm-based,”

Exactly. A true mobile computer would need an ARM chip.

OneXSugar is a step in the right direction, but they're not using the X-series and the OS is Android. Not to mention the form factor is still focused on gaming.

Stereogum soldiers on in the era of streaming and AI

Lapatine says his goal has always been to operate with transparency. He wants Stereogum to feel like talking to a friend who goes to shows and tells you about cool stuff on Bandcamp. Ultimately, he wants to build a connection with readers, help them find good music, and do it with personality. That human element is key because, he says, “I’ve never discovered anyone from the algorithm.”

Y’all are great

This series lives on my blog but has nothing to do with me. It exists to connect you, the human who’s reading this, with all the other wonderful humans that are still out there, spending their time making sure the old school web, the one made by the people, for the people, is not dying.

This is the web many people are missing, a web that is, in fact, still here, very much alive. Y’all are great.

Friday mornings are one of my favorites because I get to "meet" someone new through this series. Thanks for your work and dedication to this series.

Announcement: Pydantic AI Gateway Open Beta | Pydantic

Once you get beyond toy usage, LLM governance is a pain. That's exactly why we built Pydantic AI Gateway (PAIG)

What's included

  • One key, many models: talk to OpenAI, Anthropic, Google Vertex, Groq, or AWS Bedrock with the same key. More providers (notably Azure) are on the way.
  • Cost limits that stop spend: set daily, weekly, monthly and total caps at project, user, and key levels.
  • Built-in observability: every request can be logged to Pydantic Logfire or any OpenTelemetry backend.
  • Failover: route around provider outages automatically.
  • Open source & self-hostable: AGPL-3.0 core, file-based config, deploy anywhere. Console and UI are closed source.
  • Enterprise-ready: SSO via OIDC, granular permissions, and Cloudflare or on-prem deployment options.
  • Low latency: Finally, and perhaps most importantly, PAIG runs on Cloudflare's globally distributed edge compute network, meaning absolutely minimal latency. If you're sitting in Berlin making a request to a model near Frankfurt, you'll connect to a PAIG service running in Berlin. After the first request, it won't need to call back to our central database, so using the gateway will add single-digit milliseconds to your response time. It might even be faster, as the request will run through Cloudflare's backbone to the model provider.

Podcast App Graveyard

One of the longest-running and most well-known podcast listening apps, Stitcher was officially shut down by SiriusXM on August 29, 2023. The app originally launched in 2008, and was famous for its ability to "stream" audio (without the need to manually sync audio files to your device).

While my first podcast "app" was Zune, Stitcher was the first third-party app I used on a smartphone. Good memories. RIP Stitcher

How to find music you will love without the algorithm

With less involvement from the listener, less intentionality, it’s easy for music to simply become background noise. Research suggests that younger generations are discovering new artists at a lower rate than previous ones, and there’s a direct correlation between lower levels of music discovery and reliance on the algorithm. So, how do you find new music with intention?

The simplest and most traditional is through music media. There are countless sources of excellent music journalism and criticism, it’s just a matter of finding one that speaks to you.

Just like everything else on the internet, music has its influencers.

Sort of straddling the line between traditional music media and influencers is the world of Substack. There are tons of newsletters out there that serve up artist interviews, curated playlists, and deep dives into bands’ discographies.

Traditional radio can still be a solid source of new music if you turn away from large commercial stations owned by iHeartRadio and the like. Your local college station is a good place to start, but there are other non-commercial independent stations out there, like WFMU in New York, that steer clear of your standard pop fare.

In addition to traditional terrestrial stations, there are streaming internet stations. NTS Radio is one of the best...

...you should become a fan of labels, not just artists.

Ultimately, record labels are curators, and the best ones have a distinct identity. That doesn’t necessarily only mean releasing death metal records (though it can). It means building a vibe and a particular point of view that unifies the artists under a single umbrella.

...easily the best way to find new and interesting music is just to connect with other people who share your tastes. This can be as simple as getting recommendations from friends or an older sibling. (Or, if you’re trying to stay on top of things as you get older, a younger sibling.) But there are plenty of online communities for getting music recommendations.

Lastly, go see live music. Go see a band you know, but make sure you get there for the opener.

Great list. I've had success with all of these. Some examples.

As I discover music, I try to curate my findings through playlists

Less is More: Recursive Reasoning with Tiny Networks

Hierarchical Reasoning Model (HRM) is a novel approach using two small neural networks recursing at different frequencies. This biologically inspired method beats Large Language models (LLMs) on hard puzzle tasks such as Sudoku, Maze, and ARC-AGI while trained with small models (27M parameters) on small data (around 1000 examples). HRM holds great promise for solving hard problems with small networks, but it is not yet well understood and may be suboptimal. We propose Tiny Recursive Model (TRM), a much simpler recursive reasoning approach that achieves significantly higher generalization than HRM, while using a single tiny network with only 2 layers. With only 7M parameters, TRM obtains 45% test-accuracy on ARC-AGI-1 and 8% on ARC-AGI-2, higher than most LLMs (e.g., Deepseek R1, o3-mini, Gemini 2.5 Pro) with less than 0.01% of the parameters.

ParaRNN: Unlocking Parallel Training of Nonlinear RNNs for Large Language Models

Recurrent Neural Networks (RNNs) laid the foundation for sequence modeling, but their intrinsic sequential nature restricts parallel computation, creating a fundamental barrier to scaling. This has led to the dominance of parallelizable architectures like Transformers and, more recently, State Space Models (SSMs). While SSMs achieve efficient parallelization through structured linear recurrences, this linearity constraint limits their expressive power and precludes modeling complex, nonlinear sequence-wise dependencies. To address this, we present ParaRNN, a framework that breaks the sequence-parallelization barrier for nonlinear RNNs. Building on prior work, we cast the sequence of nonlinear recurrence relationships as a single system of equations, which we solve in parallel using Newton's iterations combined with custom parallel reductions. Our implementation achieves speedups of up to 665x over naive sequential application, allowing training nonlinear RNNs at unprecedented scales. To showcase this, we apply ParaRNN to adaptations of LSTM and GRU architectures, successfully training models of 7B parameters that attain perplexity comparable to similarly-sized Transformers and Mamba2 architectures. To accelerate research in efficient sequence modeling, we release the ParaRNN codebase as an open-source framework for automatic training-parallelization of nonlinear RNNs, enabling researchers and practitioners to explore new nonlinear RNN models at scale.

MMCTAgent: Enabling multimodal reasoning over large video and image collections

"...we developed the Multi-modal Critical Thinking Agent, or MMCTAgent, for structured reasoning over long-form video and image data, available on GitHub and featured on Azure AI Foundry Labs.

Built on AutoGen, Microsoft’s open-source multi-agent system, MMCTAgent provides multimodal question-answering with a Planner–Critic architecture. This design enables planning, reflection, and tool-based reasoning, bridging perception and deliberation in multimodal tasks. It links language, vision, and temporal understanding, transforming static multimodal tasks into dynamic reasoning workflows.

Unlike conventional models that produce one-shot answers, MMCTAgent has modality-specific agents, including ImageAgent and VideoAgent, which include tools like get_relevant_query_frames() or object_detection-tool(). These agents perform deliberate, iterative reasoning—selecting the right tools for each modality, evaluating intermediate results, and refining conclusions through a Critic loop. This enables MMCTAgent to analyze complex queries across long videos and large image libraries with explainability, extensibility, and scalability."

What happened to the comment section?

...as comments sections grew, they became less useful and more prone to toxic, hateful and counter-deliberative discussions...comments are great when the topic of blogs is more narrow, and the blogger is directly engaged. But in the context of broad and widely popular communities, they had the capability to fester.

As the web continued to grow, the issue grew. Without dedicated moderation, which many publications did try, comments sections became discordant and a liability...Washington Post was one of the first publications to remove comments, citing a lack of civility.

That trend has continued, as many sites chose to outsource discussions to social media platforms and third party networks. For sites that can manage comments, it is done through careful moderation and clear rules. But most major publications and platforms have simply opted out.

Comment sections continue to exist, but their presence is far diminished from its peak. The ActivityPub standard, the backbone of the Fediverse, was created as a partial response to their decline. Whether or not comments will find some new form is a story still unwritten.

My site probably isn't big enough (I don't know since I don't have analytics) but maintenance and moderation are reasons I don't support comments.

Why Tim Berners-Lee still believes in the web

You want to have control of your own destiny. We call it digital sovereignty. In the old days, the early days of the web, anybody used to be able to make a website. So that feeling of sovereignty as an individual being enabled and being a peer with all the other people on the web, that is what we are still fighting for, and in fact, we need to rebuild.

So many gems from this episode but this is what resonated the most with me.

Threads targets podcasters with new features, aiming to become the home for show discussions

Threads, Meta’s competitor to X, will now begin targeting a specific type of creator: podcasters. The company said on Tuesday that Threads will focus on bringing more discussions around podcasts to its app and helping creators promote their shows.

Meta explained it’s interested in the podcast community because it sees the potential in becoming the de facto place for people to talk about shows and engage with creators. Today, such discussions are distributed across social media...

The company’s also trying to tap podcasts’ deep ties to culture, which can drive discussions and encourage interactions.

However, while Threads will target the discussions that result from podcasts, the company told TechCrunch it doesn’t intend to be a podcast distribution platform.

Instead, the company will focus on giving podcast hosts more insight and analytics on how the conversations around their shows are resonating with fans. It also intends to develop more features that would help people discover podcasts they might like, and connect podcasters and listeners through conversations.

Gen Z's College Radio Revival - by Emily White

... one unexpected source of music discovery is quietly booming among Gen Z listeners: college radio.

I spoke to seven student general managers and surveyed 80+ DJs at stations across America...They told me student interest in college radio has dramatically increased in recent years. Stations that once struggled to fill airtime are now turning people away, shortening shows, alternating time slots, and running training programs just to keep up with the demand from aspiring student DJs.

What’s Driving the College Radio Renaissance?


### 1. Algorithm fatigue
Students consistently described radio as an authentic, community-driven refuge from the passive, isolated, algorithm-driven digital experiences that have defined their adolescence
### 2. Analog Nostalgia
The [resurgence](https://www.nytimes.com/2025/08/24/opinion/gen-z-technology-nostalgia.html?smid=nytcore-ios-share&referringSource=articleShare) of interest in physical media is a significant driver of Gen Z’s attraction to college radio...This manifests in a return to high-friction analog media like vinyl, flip phones, film cameras and radio.
### 3. Community, Creativity & Belonging
College radio stations serve as vital “third spaces” where students can find a community of like-minded people outside of classes and social media, said several GMs.

In a moment when the wider industry is betting on algorithms, AI, and fleeting TikTok trends, these college radio DJs remind us that young people aren’t bored of music—they’re bored of the shallow, virality-obsessed way music is marketed to them.

As someone who listens to college football games on the radio, it's comforting to hear college radio stations are thriving.

The algorithm failed music

Algorithm fatigue has been building for some time.

Gen Z might be less likely to discover a new artist they love than some older generations. But they’re also leading a resurgence in college radio. Terrestrial radio once seemed like a dying format, but many schools now report they don’t have enough time slots to accommodate all the aspiring DJs.

Even the iPod is enjoying a renaissance. Classic iPods fetch hundreds of dollars on eBay, and an entire subculture, albeit small, has arisen around modding them to extend battery life, increase storage, and add modern conveniences like Bluetooth and USB-C.

At this stage, anti-algorithm is itself an entire genre of content. Particularly on YouTube, where creators make videos about ditching streaming, stopping doomscrolling, and how the algorithm has flattened culture.

It's not either, or. Human curation and algorithms can coexist. The problem is end users are seldom given a choice.

The state of AI in 2025

Key findings


1. Most organizations are still in the experimentation or piloting phase: Nearly two-thirds of respondents say their organizations have not yet begun scaling AI across the enterprise. 2. High curiosity in AI agents: Sixty-two percent of survey respondents say their organizations are at least experimenting with AI agents. 3. Positive leading indicators on impact of AI: Respondents report use-case level cost and revenue benefits, and 64 percent say that AI is enabling their innovation. However, just

39 percent report EBIT impact at the enterprise level.

  1. High performers use AI to drive growth, innovation, and cost: Eighty percent of respondents say their companies set efficiency as an objective of their AI initiatives, but the companies seeing the most value from AI often set growth or innovation as additional objectives.
  2. Redesigning workflows is a key success factor: Half of those AI high performers intend to use AI to transform their businesses, and most are redesigning workflows.
  3. Differing perspectives on employment impact: Respondents vary in their expectations of AI’s impact on the overall workforce size of their organizations in the coming year: 32 percent expect decreases, 43 percent no change, and 13 percent increases.
