rfw300··on Legal models hallucinate in 1 out of 6 (or more) benchmarking queries
Your instinct is correct. The major legal research providers (Thomson Reuters and LexisNexis) both provide “citators”, which are human annotations of which cases and statutes have been overruled, upheld, criticized, etc. One of the issues the paper describes is the fairly ham-handed way this gets integrated into these systems, causing even more trouble.
rfw300··on Legal models hallucinate in 1 out of 6 (or more) benchmarking queries
There's more examples on page 18 of the paper: https://dho.stanford.edu/wp-content/uploads/Legal_RAG_Halluc...
rfw300··on Jan Leike joins Anthropic on their superalignment team
Yes. “Superalignment” (admittedly a corny term) refers to the specific case of aligning AI systems that are more intelligent than human beings. Alignment is an umbrella term which can also refer to basic work like fine-tuning an LLM to follow instructions.
rfw300··on Apple apologizes for iPad 'Crush' ad that 'missed the mark'
I think this misses the mark. The ad is inherently symbolic—it’s not this particular piano, but the fact that they’re destroying all of these beloved instruments of creativity in such a gratuitous and evocative manner. That’s what upsetting, not the literal fact that one piano was destroyed in the making of the ad.
rfw300··on Chinchilla Scaling: A replication attempt
Yes, compute-optimal for training only. The purpose of the paper wasn’t to determine the most economically practical model one could build, the most “intelligent” model one could build given some amount of compute.
rfw300··on GPT-4 Turbo with Vision is a step backwards for coding
I’ve been using the Claude 3 API since the models were announced. I believe it’s generally available (though capacity constrained & rate limited at present).
rfw300··on Gemma: New Open Models
A caveat: my impression of Phi-2, based on my own use and others’ experiences online, is that these benchmarks do not remotely resemble reality. The model is a paper tiger that is unable to perform almost any real-world task because it’s been fed so heavily with almost exclusively synthetic data targeted towards improving benchmark performance.
rfw300··on A brief history of the U.S. trying to add backdoors into encrypted data (2016)
I think if you’re looking for a logical answer from first principles, you won’t find one. It’s more that the legal system runs on precedent, and a book fits far more squarely in the fact patterns of previous First Amendment cases. Likely the source code case would end up with the same outcome, but it doesn’t hurt to make it more obvious.
rfw300··on Ruby 3.3 on Rails 1.0
That’s fair, but TypeScript coupled with modern JS dev tooling makes it actually a pretty palatable experience these days. Speaking as someone who used to want to jump into pits for JavaScript-related reasons.
rfw300··on Musk Demands Bigger Stake in Tesla as Price for A.I. Work
Delaware corporations cannot transition to a dual-class stock structure post-IPO.
rfw300··on Blending Is All You Need: Cheaper, Better Alternative to Trillion-Parameters LLM
The paper refers to ChatGPT as a 175B parameter LLM. This is almost certainly incorrect; the original largest version of GPT-3 was 175B but analysis of the speed and cost of the current model as well as public statements by OpenAI indicate it’s as much as 5-10x smaller.
rfw300··on Mixtral 8x7B: A sparse Mixture of Experts language model
I recently purchased a 3090 on Reddit’s hardwareswap community for $550. New GPUs are pricey right now because of shortages, but if you look around a bit it can be affordable.
rfw300··on How An ASML Lithography Machine Moves a Wafer [video]
I also thought that seems implausibly large. My guess, based on some quick research, is that a large fraction of that is procedurally generated, not human-written. Here's one example:

> Formal verification tools allow those teams to be confident that their solution is complete and error-free, and the code itself is then automatically generated... With such a model-driven engineering (MDE) approach, software developers at ASML recently replaced half a million lines of code that had been built the conventional way.

rfw300··on NY Times copyright suit wants OpenAI to delete all GPT instances
If you read the complaint, it explains this pretty well. The use of copyrighted content by search engines is fundamentally different from the way LLMs use that same content. The former directs traffic (and therefore $$) to the publisher, the latter keeps the traffic for itself.

The legal misconception I want to flag in your logic is the notion that all uses of the Common Crawl are equally infringing/non-infringing. If you use the Common Crawl to create a list of how often every word in English appears on the internet, that’s unquestionably transformative use. But if you use it to host a mirror of the NYT website with free articles, that’s definitely infringement. The legality of scraping is one matter, and the legality of what you do with the scraped content is quite another.

rfw300··on Gemini AI
That seems like a pretty remarkable pace of innovation, no?
rfw300··on Chemist suggests retraction of DeepMind robotic synthesis paper
As the paper notes, two of the authors are from DeepMind, the chemicals they are synthesizing are those predicted to be stable by a DeepMind model, and the entire work arises out of an extensive collaboration between DeepMind and the Berkeley lab: https://www.nature.com/articles/d41586-023-03745-5
rfw300··on Accelerating Generative AI with PyTorch II: GPT, Fast
The main thing is chat is just one application of LLMs. Other applications are much more latency sensitive. Imagine, for instance, an LLM-powered realtime grammar checker in an editor.
rfw300··on .io considered harmful
Ironic, considering the United States literally purchased Florida from Spain.
rfw300··on I mirrored all the code from PyPI to GitHub and analysed it
Computers aren’t humans. There’s no reason licenses should treat them the same way when completely different considerations of fairness and economic impact apply.
rfw300··on Refusing to teach kids math will not improve equity
This is incorrect as of last year: https://en.wikipedia.org/wiki/Carson_v._Makin

There is a powerful political and legal movement behind the idea that state-funded religious indoctrination is not only permitted, but required.

rfw300··on Open source code with profanity in comments is statistically better
I don’t think anyone is saying it’s causation, the correlation is in and of itself interesting!
rfw300··on Open source licenses need to leave the 1980s and evolve to deal with AI
That’s because you’re a human. Copyright and fair use law was built for people, and letting AI models have the same privileges will lead to worse outcomes. What’s so wrong about saying that it isn’t fair use for a machine to learn from your copyrighted data?
rfw300··on OpenAI’s policies hinder reproducible research on language models
The article seems premised on a misunderstanding that OpenAI is a research lab. For all intents and purposes, it’s a for-profit subsidiary of Microsoft, and there’s little financial incentive for it to maintain old models for others’ benefit.
rfw300··on Research shows we can only accurately identify AI writers about 50% of the time
I think the issue with the “AI doing X better than most people is an indictment of the people or the way we teach them” genre of takes is that it assumes the current state of AI progress will hold. Today, it writes at a college freshman level, but yesterday it was at a fourth grade level. If it surpasses most or all professional writers tomorrow, what will we say?
rfw300··on PyTorch 2.0
In fact there is an environment variable that enables exactly that. There are obviously performance issues associated with that, but it does work.
rfw300··on SBF Arrested by Bahamian Authorities
And the implied prediction was also dead wrong. So perhaps people should update their priors.
rfw300··on NY State Supreme Court reinstates all fired unvaccinated employees with backpay
It is very important to note that in the state of New York, the trial court (the lowest level court) is called the Supreme Court. So while this ruling is notable, it is not the state’s highest court ruling on the matter. This ruling will be appealed by the government and likely reversed on appeal.
rfw300··on Spotify to acquire Heardle
And the desktop application is itself missing a bunch of features from the mobile app!
rfw300··on Meta slashes hiring plans, girds for 'fierce' headwinds
I think the point is that Facebook's contribution to society (with its actual product, not its tech work) has been negative; its goal is to turn every knob it can find to get people to spend more time on Facebook, not actually solve any problems. All businesses are selfish, but some manage to meaningfully improve some aspect of people's lives along the way.
rfw300··on SEC charges Nvidia with inadequate disclosures about impact of cryptomining
It’s worth noting many of these regulations came into existence (or became stringently enforced) because of 2008.
