Redis 8 just leveled up: semantic caching that understands meaning—not literal keys. Vector Sets + LangCache ditch redundant LLM calls, and Flex scales affordably via SSD. Your budget will thank you.

Grok has “Unhinged Mode,” no safety framework, and vibes like it skipped QA and ethics class. Until xAI proves it can adult, treat Grok like beta software with a flamethrower. Pause all POCs. Safety first.
