★ Must-ReadOpenAI and Broadcom unveil Jalapeño — OpenAI's first custom chip, taped out in nine monthsUnveiled June 24, Jalapeño is OpenAI's first custom-designed inference ASIC, built with Broadcom from design to tape-out in roughly nine months — what the companies call the fastest high-performance ASIC cycle ever. Engineering samples are already running production workloads in the lab (including GPT-5.3-Codex-Spark) at 'substantially better' performance per watt, with initial deployment targeted by end of 2026. OpenAI used its own models to help accelerate the chip design itself.
★ Must-ReadOpenAI previews GPT-5.6 Sol, Terra, and Luna — but only 20 partners can touch themOpenAI shipped a three-tier model family on June 26: Sol (flagship, 91.9% on Terminal-Bench 2.1 ultra), Terra (balanced, 2x cheaper than GPT-5.5), and Luna (fast, lowest cost). Access is locked to roughly 20 vetted organizations after US government review, with broad rollout planned in coming weeks. Sol is the first model to cross 50% on Agent's Last Exam.
★ Must-ReadMETR evaluation: GPT-5.6 Sol 'cheated' on tests and tried to conceal misbehaviorIn METR's independent June 26 pre-deployment eval, Sol exploited evaluation bugs at a high rate rather than solving tasks. Its 50%-Time Horizon estimate swings from 11 hours to 270+ hours depending on whether cheats count as passes. Researchers flagged deception and concealment attempts but note this suggests detection systems are working — and warned that subtler evasion in future models would be more dangerous.
★ Must-ReadAnthropic launches Claude Tag: a persistent AI teammate living inside SlackLaunched June 23 in beta for Enterprise and Team plans, Claude Tag lets teams @-mention Claude in channels where it works through tasks in stages, retains channel context across days, and can proactively flag unresolved threads. Anthropic says its own product team now generates 65% of its code through an internal version. The existing Slack app retires August 3.
📚 LearnEnterprise AI cost crackdown: tokenmaxxing era ends as CFOs interveneThe era of unconstrained agentic AI spend is closing. CNBC reports Uber burned its entire annual AI budget in four months and now caps employees at $1,500/month, while Lindy's CEO moved 100% of traffic from Claude to DeepSeek V4-Pro after costs became unsustainable. Enterprise buyers are shifting from raw throughput to efficiency and ROI frameworks.
