Our position on open-weights models

341 surprisetalk 2026-07-27 22:21:20 UTC anthropic.com Llama Share 441

The author of Anthropic does not support banning open-weights models, but instead advocates for keeping powerful chips out of authoritarian hands and requiring safety testing of all capable models. The author's primary concern is authoritarian governments building more powerful AI models than the US, and their secondary concern is powerful AI models being misused for cyberattacks or biological attacks.

Watching Go's new garbage collector move through the heap

Go 1.26's new garbage collector, Green Tea, improves performance by reducing cache misses and increasing speed, but its impact on L3 cache is initially misleading. By analyzing L1 cache metrics, we see that Green Tea reduces L1 cache misses and improves overall performance, but Go still struggles with memory fragmentation due to its non-moving collector.
