Is AIC-based model reduction before adding latent class membership a defensible modelling strategy?
I am an MSc Biostatistics student working on a study of willingness to quit smoking. I derived a 3-class latent variable using Latent Class Analysis (LCA) from FTND and two motivational indicators. Since these variables were used to construct the latent class, I excluded them from my logistic regression to avoid modelling both the component indicators and their derived latent construct simultaneously. I first fitted a full logistic regression using the remaining conventional predictors, performed AIC-based backward model selection to obtain a parsimonious model, and then added latent class membership to evaluate its incremental explanatory value using changes in AIC and BIC. Would you consider this a statistically sound and defensible modelling strategy? Are there any methodological references or alternative approaches that you would recommend?

Amazon engineers are reportedly distilling Anthropic models to cut costs before new token-based pricing kicks in
Amazon engineers are already distilling Anthropic models into smaller, cheaper versions for internal use. Starting next year, Amazon will pay by tokens processed rather than compute hours, which could push costs up sharply. The company is also exploring alternatives like OpenAI.

EU seeks AI independence as Austria proposes luring Anthropic to Europe
Austria's State Secretary for Digitalization, Alexander Pröll, is calling on the European Commission to explore bringing Anthropic to Europe. He's responding to the U.S. ban on advanced AI models from OpenAI and Anthropic for foreign users. The initiative is likely unrealistic, though. And the alternative floating in the background, Chinese AI models, would just trade one dependency for another.

Huge improvement in long-form technical workflows
Hey @ CandyButcher , welcome to the community! Really appreciate you taking the time to share this. It’s really nice to hear that ChatGPT has felt more useful for long, iterative software projects, not just one-off prompts. The example around building a document extraction pipeline module by module is especially helpful context. This kind of real-world feedback is helpful, and I’m glad it’s been making a noticeable difference in your day-to-day work. - Sunny
Comment on Here’s To Drinking Safely With AI! by David Zinczenko
Interesting tech, but from my own experience, no gadget can stop someone who is not ready to stop. I needed full immersion away from my daily triggers, not predictions or alerts. That is why Inpatient rehab https://canadiancentreforaddictions.org/understanding-addiction/cocaine-addiction/ was the only thing that actually worked for me. These tools might help some, but real change comes from within.

Delhi EV policy to accelerate electric two wheeler adoption
The Delhi government on Monday approved a new Electric Vehicle (EV) Policy that is expected to accelerate electric two wheeler adoption through purchase incentives, mandatory EV only registrations from 2028 and a major expansion of charging infrastructure. The policy offers incentives of Rs 30,000 for electric two wheelers in the first year, Rs 20,000 in the second year and Rs 10,000 in the third year. From April 1, 2028, only electric two wheelers will be eligible for fresh registration in Delhi. Existing petrol and diesel vehicles can continue to be used as per the current rules. The move is expected to benefit electric two wheeler manufacturers such as Ather Energy, Ola Electric, TVS Motor Company, Bajaj Auto and Ultraviolette Automotive. Delhi is one of the country's largest two wheeler markets and the policy provides long term visibility for EV adoption. Reacting to the announcement, Tarun Mehta, cofounder and CEO of Ather Energy, said that Delhi has approved one of the most significant city level EV policies in India. "The combination of incentives, phased electrification mandates and charging infrastructure creates a very strong foundation. If Delhi can become a majority EV market, it has the opportunity to become a benchmark for the rest of the country," Mehta said in a post on X . He added that long term policies give the EV ecosystem the confidence to continue investments and product development. Narayan Subramaniam, CEO and Head of Design at Ultraviolette Automoti…
Pair Nova 2 Lite with Claude for cost-optimized document processing
In this post, we show how pairing Amazon Nova 2 Lite with Anthropic’s Claude Sonnet 4.6 delivers an efficient solution for digitizing scanned documents at scale. We built a two-model pipeline on Amazon Bedrock for digitizing scanned yearbook pages. Amazon Nova 2 Lite handles native multimodal extraction in a single call: detecting photos, extracting visible names with coordinates, and returning page-level metadata. Claude Sonnet 4.6 then performs spatial reasoning to match names to faces based on page layout.

[Linkpost]Frame Error
Today I want to explain what I call “ frame errors ”: a third kind of mistake, distinct from logical fallacies and empirical errors. You can get every fact right and every inference valid, and still be wrong, because your framework for reasoning about the problem is structurally inadequate. In some sense, the idea is not new. Many other thinkers have pointed out specific instantiations of these mistakes before. However, I coin the “frame error” term to draw attention to the common category across these mistakes, provide tools and worked examples to help readers spot these errors when they occur, and offer advice to help readers understand and identify the meta-errors that might lead them or others to commit frame errors. This post will go through five common classes of frame errors, with worked examples. I will start with examples that you likely have heard of before, and then end with more novel examples where I was the first person to explicitly point out such errors. Along the way, I provide conceptual tools to model good thinking, so you can hopefully learn useful rationality and reasoning tips even if you do not buy the frame error construct.

Multi-tenant LLM analytics with row-level security: How we built a secure agent on AWS
In this post, we show you how PAR built a production-ready multi-tenant LLM analytics system that enforces row-level security through a three-layer architecture: cryptographic request signing with AWS SigV4, semantic validation on Amazon Bedrock, and programmatic data isolation via Split-Plane SQL. We demonstrate how each layer operates independently to reduce the risk of cross-tenant data exposure, even when the LLM itself is compromised or manipulated.

AI will make biological extinction risks worse before it makes them better
An argument goes: If we don't build aligned artificial superintelligence, we risk driving ourselves extinct for some other reason. We should rush to build ASI quickly, in spite of the risks—the longer we wait, the more vulnerable we are to extinction from a different cause. Other than ASI, the biggest extinction risk is synthetic biology. Some lab could (accidentally or on purpose) develop a highly transmissible, 100% fatal super-plague that wipes out humanity. An aligned ASI could stop that from happening by shutting down dangerous biological research, or by developing advanced countermeasures that stop the spread of deadly infections. So the argument goes: We need to build ASI to save us from non-AI extinction risks. However, that argument doesn't work. In the near term, AI will make biological risks worse , not better. AI will accelerate scientific research, which will bring us closer to the level of knowledge necessary to build extinction-level pathogens. And in the long term, the way ASI eliminates biological x-risk is by taking control of the world. Cross-posted from my website . In the near term, AI makes biorisk worse Some people imagine that AI models would accelerate defensive research while refusing to assist with developing bioweapons. This plan has two minor issues and one fatal one. The first minor issue: Current AI model refusals are not robust, and there are workarounds to get information out of them for people who want to. It's very hard for AI developers to…
