Systima tested XML vs MD vs JSON prompts across 4 frontier models, 10 tasks, 600 calls.

Delimiter format almost never matters.

But they found a reproducible 20% prompt injection vulnerability in one model+format combo. That DOES matter.

AI agents can break GDPR and the EU AI Act by just doing their job.

The law assumes static systems, but agents can be dynamic.

Can you save on LLM tokens using images instead of text? What happens if you convert your prompts to an image before running?

Good ideas! Not responding so often is an immediate 'win', and actually I think the care/attention of a longer, more thorough email is often better than a more lazily bashed-out fast response..

Interesting post, but in practice how is one supposed to eliminate the low-velocity activities (social n; personal prod; ref search; calendars β€” per the example screenshot)? These aren’t (all) pointless indulgences and without them, would the wheels not begin to fall of of work/life?

Context engineering | Chris Loy As our use of LLMs has changed from conversational chatbots and into integral decision-making components of complex systems, our inference approach must also evolve.

It's very tempting to send them our brand guidelines so they can really get it right. πŸ˜‰

It's good to see agentic SEO starting to ripple outward – This just isn't in the way I expected! When others start borrowing your language it's usually a sign that you’re setting the pace.

I guess our branding is contagious! Someone became 'heavily inspired' by it, added one extra letter to our brand name, and threw it into Loveable.dev for a quick landing page rip-off. Same mission, same tone.

I am curious: Do the others have business models that genuinely couldn’t support higher wages? Or it’s more… a choice?

By the 70s/80s, virtually every new or modernised primary school was built with a multipurpose hall that doubled as dining room, assembly hall, and PE space β€” and the apparatus became a standard feature.

β€’ Firms like Nissen, Huck, and Universal Services supplied standard modular wall-mounted climbing frames, foldable for hall space, with attachable ladders, ropes, and beams.
β€’ Local Education Authorities (LEAs) often bulk-purchased these to equip new or refurbished schools.

Mine (in the 90’s) had this. Summarised from ChatGPT:

β€’ The govt’s School Building Programme (and later DES) building standards included specifications for gymnasia and approved apparatus.
