This is how it's done.

A strong and principled response by WilmerHale to the illegal Executive Order attack - a form of attempted government intimidation declared unconstitutional by a federal judge.

This is how to guard the rule of law.

The hardest part about finetuning is that people don't have labeled data. Today, @databricks.bsky.social introduced TAO, a new finetuning method that only needs inputs, no labels necessary. Best of all, it actually beats supervised finetuning on labeled data. www.databricks.com/blog/tao-usi...
TAO: Using test-time compute to train efficient LLMs without labeled data
LIFT fine-tunes LLMs without labels using reinforcement learning, boosting performance on enterprise tasks.

Excited to share our work with friends from MIT/Google on Learned Asynchronous Decoding! LLM responses often contain chunks of tokens that are semantically independent. What if we can train LLMs to identify such chunks and decode them in parallel, thereby speeding up inference? 1/N

We're probably a little too obsessed with zero-shot retrieval. If you have documents (you do), then you can generate synthetic data, and finetune your embedding. Blog post lead by @jacobianneuro.bsky.social shows how well this works in practice.

In case it is not clear from my reposts, the Trump administration is engaged in an illegal AND unconstitutional to seize power over the federal government away from Congress and the courts. "Pausing" payment on the government's bills is just one part of it, but it is among the worst.

All the more convinced that the markets don't understand AI. Both the irrational hype and the irrational pessimism. DeepSeek is incredibly bullish for GPU sales...

Very excited that our Series J is complete. Especially thrilled to have our friends at Meta on board!

Meta rarely invests in startups, but it works with Databricks on the Llama open-source models that Meta trains.

Reflections on NeurIPS: There's always a big theme people seem to be preoccupied with. This year, it was the continuation of scaling/progress. Will it continue? What will the next generation of models hold? I even got to sass Dylan Patel (not on bsky) over it. Here are my personal thoughts 🧵

We just released the Databricks synthetic evals SDK! 🎉

We’ve found that synthesizing evals is a great way to hill climb your AI system before you’re able to get labels from domain experts.

We’ve also recently release a new diff UI that lets you both qualitatively and quantitatively view results!

Checking some great work my team did on continued pretraining of LLMs!
What’s the most effective way to add new domain knowledge into an open LLM? A new blog post from my team covers experiments we did at the beginning of the year to start answering this question. It starts, unsurprisingly, with sweeping your learning rate… www.databricks.com/blog/charact...

Building benchmarks is important because they shine a spotlight on the weaknesses of existing language models and so can guide the community on how to improve them.
