This brief covers the trailing ~72 hours (June 23–26, 2026). Every item below was confirmed on the originating organization’s own page, with a published date inside the window. It was a busy stretch led by OpenAI — a custom inference chip, a new economic-research paper, and a science case study — alongside Anthropic shipping a new way to work with Claude.
OpenAI and Broadcom unveil “Jalapeño,” a custom LLM inference chip
OpenAI · June 24, 2026
OpenAI and Broadcom unveiled Jalapeño, OpenAI’s first Intelligence Processor: an accelerator designed from scratch for LLM inference and the first chip in a multi-generation compute platform the two companies are building together. OpenAI says the program went from initial design to manufacturing tape-out in nine months — what it believes is the fastest ASIC development cycle ever for a high-performance advanced semiconductor — with parts of the design accelerated by OpenAI’s own models. Engineering samples are already running ML workloads in the lab, and the platform is targeted for initial deployment at gigawatt scale by the end of 2026.
“Jalapeño is part of our long-term full-stack infrastructure strategy to make compute more abundant, resulting in AI which is faster, more reliable, more affordable for people and businesses, and can be used to solve more important problems.” — Greg Brockman, President and Co-Founder, OpenAI

Anthropic introduces Claude Tag, starting on Slack
Anthropic · June 23, 2026
Anthropic launched Claude Tag, a way for teams to delegate work to Claude as a member of a Slack channel. Anyone in a channel can tag @Claude to hand off a task, and the model builds context over time, takes initiative when “ambient” behavior is enabled, and can work asynchronously over hours or days with tightly scoped, admin-controlled access to tools and data. It runs on Opus 4.8, is available today in beta for Claude Enterprise and Team customers, and replaces the existing Claude in Slack app.
“Tagging @Claude is now one of the main ways we get things done at Anthropic. Today, 65% of our product team’s code is created by our internal version of Claude Tag.” — Anthropic

OpenAI publishes economic-research paper on Codex adoption
OpenAI · June 25, 2026
OpenAI released an Economic Research paper, “The shift to agentic AI: evidence from Codex,” documenting how agentic tools are changing knowledge work. The company reports that by May 2026, 80.6% of sampled individual Codex users made at least one request estimated to exceed 30 minutes of human work and 25.6% made one estimated to exceed eight hours. Internally, Codex has become the primary AI tool for every department — including Legal, Finance, and Recruiting — and non-developer adoption grew 137x among individual users since August 2025.
“As the tools improve, people use them for longer, more complex, and more cross-functional work. As time goes on, this is likely to be what the future of work looks like.” — OpenAI

OpenAI details how GPT-5 helped solve a 3-year-old immunology mystery
OpenAI · June 23, 2026
OpenAI published a case study on immunologist Derya Unutmaz of The Jackson Laboratory, who used GPT-5 Pro to revisit a shelved 2022 experiment on how glucose shapes T-cell development. The model proposed a mechanism — that deoxyglucose interferes with the protein IL-2, removing a barrier to T cells becoming inflammatory Th17 cells — and, in a separate test, correctly predicted the result of an unpublished experiment on lymphoma-killing CD8+ cells. OpenAI notes that subject-matter expertise remains essential to judge the significance of any AI-generated insight.
“GPT-5 came up with this really remarkable insight that retrospectively, makes perfect sense.” — Dr. Derya Unutmaz, The Jackson Laboratory and the University of Connecticut
