Ireland's Tallaght District Heating Scheme uses waste heat from an #AWS data center to sustainably heat homes & buildings. By 2050, district heating could supply 87% of Dublin's heating demand. I expect to see this model widely adopted in the coming years. https://t.co/anFoeqsFYV

Do Large Language Models really "understand" the world, or just give the appearance of understanding? Evidence (e.g., Othello-GPT) shows LLMs build models of how the world works, which makes me comfortable saying they do understand. More in The Batch: https://t.co/e0JGU2wUbf

Oops haven't tweeted too much recently; I'm mostly watching with interest the open source LLM ecosystem experiencing early signs of a cambrian explosion. Roughly speaking the story as of now:

1. Pretraining LLM base models remains very expensive. Think: supercomputer + months.
2. But finetuning LLMs is turning out to be very cheap and effective due to recent PEFT (parameter efficient training) techniques that work surprisingly well, e.g. LoRA / LLaMA-Adapter, and other awesome work, e.g. low precision as in bitsandbytes library. Think: few GPUs + day, even for very large models.
3. Therefore, the cambrian explosion, which requires wide reach and a lot of experimentation, is quite tractable due to (2), but only conditioned on (1).
4. The de facto OG release of (1) was Facebook's sorry Meta's LLaMA release - a very well executed high quality series of models from 7B all the way to 65B, trained nice and long, correctly ignoring the "Chinchilla trap". But LLaMA weights are research-only, been locked down behind forms, but have also awkwardly leaked all over the place... it's a bit messy.
5. In absence of an available and permissive (1), (2) cannot fully proceed. So there are a number of efforts on (1), under the banner "LLaMA but actually open", with e.g. current models from @togethercompute, @MosaicML ~matching the performance of the smallest (7B) LLaMA model, and @AiEleuther , @StabilityAI nearby.

For now, things are moving along (e.g. see the 10 chat finetuned models released last ~week, and projects like llama.cpp and friends) but a bit awkwardly due to LLaMA weights being open but not really but still. And most interestingly, a lot of questions of intuition remain to be resolved, e.g. especially around how well finetuned model work in practice, even at smaller scales.

What are activities outside of building software that senior+ / staff & above could take part in to improve their organization?

Here are a few. What else have you observed being 'strategic' ones that could have gains on the mid-term or on the long run?

In the 1960s, the National Training Laboratories Institute developed a pyramid model to represent the retention rate of information from various activities.

The general takeaways:

• Lecture/reading are not enough
• Teaching is the most powerful form of learning

After the dust settles from a major event, whether inflation was just caused by temporary supply shocks or by monetary debasement is answered by one key test:

Did aggregate prices go back to their previous level, or no?

Randomness is critical property for crypto and the World Computer. Unfortunately, computers are terrible at generating randomness without external input... and the EVM has no external input.

And we finalized!

Happy merge all. This is a big moment for the Ethereum ecosystem. Everyone who helped make the merge happen should feel very proud today.
