A weekly roundup of AI/ML news from July 3–11, 2026 covering five major developments: GPT-5.6's general availability with programmatic tool calling and multi-agent orchestration as a platform primitive; GPT-Live's full-duplex voice architecture that separates conversational and reasoning loops; a price war in the agentic workhorse model tier with Grok 4.5 and Meta's Muse Spark 1.1; Meituan's LongCat-2.0 open-weight MoE model trained on alternative AI ASICs; and the GhostApproval security vulnerability found across six major AI coding assistants exploiting symlinks to bypass human approval. The overarching theme is that AI is reducing friction between deciding and acting, shifting the key metric from cost-per-token to cost-per-completed-task, while trust boundaries and agent security become critical concerns.
