What changed this week, what the frontier models still win on, and what the practical question actually is.https://ku5e.com/blog/the-ethical-ai-company-billed-you-for-using-competitor-tools/Sun, 10 May 2026 22:30:00 +0000https://ku5e.com/blog/the-ethical-ai-company-billed-you-for-using-competitor-tools/Anthropic's billing system scanned user repositories for competitor keywords and charged extra or blocked access when it found them. The gap between stated values and operational behavior.https://ku5e.com/blog/claude-code-on-deepseek-17x-cheaper/Thu, 07 May 2026 10:27:00 +0000https://ku5e.com/blog/claude-code-on-deepseek-17x-cheaper/DeepClaude routes Claude Code's tool calls through DeepSeek instead of Anthropic's models. Same tool ecosystem, approximately 17x lower cost. How it works and where it falls short.https://ku5e.com/blog/ai-outperformed-er-doctors-in-a-harvard-trial/Wed, 06 May 2026 19:22:00 +0000https://ku5e.com/blog/ai-outperformed-er-doctors-in-a-harvard-trial/Harvard published a controlled trial showing AI outperformed emergency physicians in triage diagnoses.
