Ramp's engineering team uses Sierra's Agent SDK to automate 90% of customer service cases, showcasing practical AI implementation in enterprise operations @btaylor
AI startups are asking developers to work 6+ days per week, 80+ hour weeks, creating irony where AI companies meant to reduce human work are demanding more intensive labor @GergelyOrosz
Hardware design and fabrication is becoming 10x more accessible due to new wave of startups refactoring chip design and component sourcing, making previously capital-intensive processes more approachable @scottbelsky

New benchmark measures how much AI models will play along with users pushing them in delusional or potentially psychologically dangerous directions, with early signals that full GPT-5 may be a less psychologically risky model @emollick
Traditional ML fairness audits don't work in the LLM era, as medical LLMs may have equal treatment recommendation rates across groups but differ in empathetic vs dismissive phrasing, raising questions about what "groups" even mean now @irenetrampoline
AI "personality" is becoming the battleground for consumer AI development, with implications for how models interact with users and potential psychological impacts @emollick
Research warns about prompt injection vulnerabilities in AI agents, where attackers can trick systems into stealing private data through malicious instructions embedded in external content @StevenyzZhang
