Incremental Multimodal Graphs Declare one traceable feature model, store expensive multimodal outputs once, then query the same facts across LanceDB, Lance Graph, DuckPGQ, and LadybugDB. The graph engine should be a choice, not a rewrite. georgheiler.com/2026/06/29/i...

The fact that the US government specifically ordered the suspension of Fable access to non-US citizens (www.anthropic.com/news/fable-m...) raises exactly the kind of technological sovereignty concerns I discussed in my QCon keynote a few months ago (www.infoq.com/presentation...)
anthropic.com
Statement on the US government directive to suspend access to Fable 5 and Mythos 5
The US government has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States.
