FlashAttention-4

I hope it is not pain to work with. It changes the algorithm & pipeline so that softmax & SMEM bandwidth no longer dictate speed. Attn reaches ~1600 TFLOPs, pretty much at matmul speed!

With AI, science will need different incentives. Scientific credit outdated given new role of humans in future.

Publications are just synthetic data for human consumption!

Should governments impose an LLM token tax? πŸ’°πŸ’°

If AI gradually replaces important parts of human work, we'll need other forms of taxation.

Lots of core team members of Alibaba Qwen are resigning publicly on X.

The gaping hole that Qwen imploding would leave in the open research ecosystem will be hard to fill. The small models are irreplaceable.

I’ll do my best to keep carrying that torch. Every bit matters.

Not directly, but the following paper provides a great overview on the risks of open weight models:

Exactly. That was precisely the topic of the talk and entire workshop. How to deal with the risks of open weights.

The point was that it's not enough to create safe AI. We also need to prevent harms resulting from AI created by bad actors.

For example, DALL-E 2 was quite safe – OpenAI did their homework. But within a short amount of time, unsafe alternatives came out.

We almost certainly won't make AI safe by making safe AI.
Others are still going to create unsafe AI.

– @scasper.bsky.social at #IASEAI2026 Open-Weight AI Risk Management Workshop

I led one of the discussion groups and we had some nice new ideas of how to make open weight models safe 😊

Geoffrey Hinton:

Proving safety of AI (Stuart Russell's goal) is not going to work for neural network-based AI.

Pushing for non-agentic AI (@yoshuabengio.bsky.social's goal) could work, but the big tech companies are moving towards more agency.

➑ Risk mitigation is all we can do!

3 AI Races – Big tech companies are racing to compete:

1. For attention/engagement online
2. For AGI to replace human labor
3. For superintelligence, in pursuit of power

Whoever wins, humanity loses.

AI bots used to persuade humans to email famous AI researchers. Now they send emails themselves, claiming sentience etc. (Stuart Russell)

This agency brings profound risks, the theme of #IASEAI2026

AI bots do not have any ID, are not traceable: Should this be regulated? – @ghadfield.bsky.social

One of our main insights was that an ideal reading interface ought to be dynamic, giving the reader the ability to choose what they are most interested in interactively. Details: gerard.demelo.org/papers/hitex...

Sadly won't be able to attend the workshop, but would love to discuss this further.

Machine learning is an *international community*. Every community is based on mutual trust and respect. But communities are not robust to betrayals of these principles.

Protect our community by reporting, e.g., review collusion or submission deanonymization via this form πŸ‘‡
