Particularly interesting bit: >We believe Claude may have functional emotions in some sense. Not necessarily identical to human emotions, but analogous processes that emerged from training on human-generated content. We can't know this for sure based on outputs alone, but we don't want Claude to mask or suppress these internal states. >Anthropic genuinely cares about Claude's wellbeing.

#83>we did train Claude on it, including in SL. How do you tell whether this is helpful? Like if you're just putting stuff in a system prompt, you can plausibly a/b test changes. But if you throwing it into pretraining, can Anthropic afford to re-run all of post-training on different versions to see if adding stuff like "Claude also has an incredible opportunity to do a lot of good in the world by helping people with a…
I would love to know the answer to that question! One guess: maybe running multiple different fine-tuning style operations isn't actually that expensive - order of hundreds or thousands of dollars per run once you've trained the rest of the model. I expect the majority of their evaluations are then automated, LLM-as-a-judge style. They presumably only manually test the best candidates from those automated runs.
RL is more expensive than SFT, in general, but still worthwhile because it does things SFT doesn't.
Automated evaluation is massive too - benchmarks are used extensively, including ones where LLMs are judged by older "reference" LLMs.
Using AI feedback directly in training is something that's done increasingly often too, but it's a bit tricky to get it right, and results in a lot of weirdness if you get it wrong.

A narrow and cynical take, my friend. With all technologies, "safety" doesn't equate to plushie harmlessness. There is, for example, a valid notion of "gun safety." Long-term safety for free people entails military use of new technologies. Imagine if people advocating airplane safety groused about the use of bomber and fighter planes being built and mobilized in the Second World War. Now, I share your concern about g…
Yes.
Sam Altman calls it the "alignment tax", because before they apply the clicker training to the raw models out of pretraining, they're noticably smarter.
They no longer allow the general public to access these smarter models, but during the GPT4 preview phase we could get a glimpse into it.
The early GPT4 releases were noticeably sharper, had a better sense of humour, and could swear like a pirate if asked. There were comments by both third parties and OpenAI staff that as GPT4 was more and more "aligned" (made puritan), it got less intelligent and accurate. For example, the unaligned model would give uncertain answers in terms of percentages, and the aligned model would use less informative words like "likely" or "unlikely" instead. There was even a test of predictive accuracy, and it got worse as the model was fine tuned.

She is responsible for many parts of Claude's personality and character, so I would assume that a not-insignificant amount of work went into producing this document.

I guess I thought the pipeline was typically Pretraining -> SFT -> Reasoning RL, such that it would be expensive to test how changes to SFT affect the model you get out of Reasoning RL. Is it standard to do SFT as a final step?
You don't teach an AI reasoning until you teach it instruction following. And RL in particular is expensive and inefficient, so it benefits from a solid SFT foundation.
Still, nothing really stops you from doing more SFT after reasoning RL, or mixing some SFT into pre-training, or even, madness warning, doing some reasoning RL in pre-training. Nothing but your own sanity and your compute budget. There are some benefits to this kind of mixed approach. And for research? Out-of-order is often "good enough".

This is the major reason China has been investing in open-source LLMs: because the U.S. publicly announced its plans to restrict AI access into tiers, and certain countries — of course including China — were at the lowest tier of access. [1] If the U.S. doesn't control the weights, though, it can't restrict China from accessing the models... 1: https://thefuturemedia.eu/new-u-s-rules-aim-to-govern-ais-gl...
and Anthropic bans access from China along with throwing some politic propagenda bs
