<ul>
<li><strong>Anthropic launches Programmatic Tool Calling to slash latency</strong>: Anthropic introduced Programmatic Tool Calling (PTC) for Claude Opus and Sonnet 4.6, allowing the model to orchestrate multiple tools inside a sandboxed container rather than returning to the context window for every step. This architectural shift reduces input tokens by 24% and improved search task accuracy by 11% in early benchmarks. PTC is now the default for web search via the API, effectively solving the ‘token bloat’ problem in complex agentic workflows. <a href="https://app.daily.dev/posts/0Sd168FyP" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AWS strikes $50 billion deal to host OpenAI Frontier</strong>: Amazon has entered a massive multi-year strategic partnership with OpenAI, positioning AWS as the exclusive third-party cloud provider for OpenAI Frontier. This $50 billion investment includes the launch of an OpenAI-compatible Projects API in Amazon Bedrock and the new ‘Strands Labs’ for experimental agentic AI. The move significantly reshapes the cloud AI landscape, challenging Microsoft’s long-standing dominance over OpenAI’s infrastructure. <a href="https://app.daily.dev/posts/BuADMJIIV" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Iran-linked cyberattacks escalate following regional strikes</strong>: The UK’s NCSC and security researchers at SentinelOne are warning of a surge in Iranian state-aligned cyber activity, including wiper malware and infrastructure disruption. This follows a major military operation on February 28 that briefly dropped Iran’s connectivity to 1%, triggering retaliatory DDoS and phishing campaigns from over 60 hacktivist groups. AWS data centers in the UAE and Bahrain have already reported structural damage and service disruptions from drone and missile strikes. <a href="https://app.daily.dev/feed-by-ids?id=1ChXx41Ct&amp;id=rar5XOK6I&amp;id=wK8ROj11e" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>The great B2B AI optimization delusion</strong>: B2B companies are burning cash optimizing for Perplexity because of ‘tech Twitter buzz,’ despite it having zero influence on actual procurement. Data shows ChatGPT and Microsoft Copilot own nearly the entire enterprise market, yet brands continue to chase niche AI referral traffic that doesn’t convert. It’s the 2026 version of buying ads on a platform where your customers don’t actually exist. <a href="https://app.daily.dev/posts/xnvqZnJQV" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AI complexity is the new technical debt</strong>: IDC reports that large organizations are running dozens of AI proof-of-concepts, but only 11% actually make it to production. Most of these projects are just adding data fragmentation and integration nightmares under the guise of ‘innovation.’ We’re effectively automating the creation of legacy systems before the first version even ships. <a href="https://app.daily.dev/posts/gK91ABz9x" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Ars Technica reporter fired for AI-generated hallucinations</strong>: A senior AI reporter was sacked after using Claude and ChatGPT to ‘extract source material’ that ended up fabricating quotes from an engineer. It’s a poetic disaster: a tech journalist covering AI agents got taken down by the very ‘slop’ he was supposed to be investigating. Apparently, using AI to write about AI is the fastest way to lose your job in 2026. <a href="https://app.daily.dev/posts/O3BSPfqbD" target="_blank" rel="noopener nofollow">Read more</a></li>
