TLDR

Anthropic API model deprecations June 15 — claude-sonnet-4-0 and claude-opus-4-0 are being retired; hardcoded model strings in API calls will error after that date.
Claude second outage in 4 days (Jun 5) — All models, claude.ai, Claude Code, and Cowork affected for ~3.5 hours; resolved by 18:27 UTC.
ChatGPT crosses 1B monthly active users (Jun 2–3) — Fastest app in history to hit the milestone; Claude at 56M but growing 640% YoY.
NVIDIA Cosmos 3 now available (May 31) — Open-weightA model whose trained weights are published for anyone to download and run.NTIA ↗ world foundation model for physical AI (64B + 16B params) on Hugging Face; key for robotics and autonomous driving pipelines.
Colorado AI Act June 30 deadline is gone — New law (SB 189, signed May 14) delays enforcement to January 1, 2027 and scales back requirements.

Things your engineering team should look at or do this week.

Audit API calls for claude-sonnet-4-0 and claude-opus-4-0 before June 15 — These model identifiers return errors after that date. Migrate to claude-sonnet-4-5 / claude-opus-4-5 (or jump to claude-opus-4-7 for agenticDescribes AI systems where a model uses tools and decides its own steps instead of following a fixed script.Anthropic ↗ workloads — same price or cheaper with larger context). Consumer claude.ai and Claude Code managed environments are unaffected; only direct API calls using the versioned -4-0 strings break. (Anthropic model deprecations | MindStudio migration guide)
Review agent retry / fallback logic after two Anthropic outages this week — June 2 (global, ~2 hours) and June 5 (global, ~3.5 hours) both took down the entire API tier simultaneously. If your agent pipelines rely on a single provider without a fallback, this is the week to add one. (TechRadar outage coverage | Thoughtworks write-up)

NVIDIA Cosmos 3 (May 31) Open Source Robotics/IoT — Open world foundation model for physical AI built on a Mixture-of-Transformers architecture combining vision reasoning, world generation, and action prediction in one system. Cosmos 3 Nano (16B) and Cosmos 3 Super (64B) are available now on Hugging Face and build.nvidia.com as NIM microservices; Cosmos 3 Edge (real-time inferenceRunning a trained model on new input to get an output, as opposed to training it.NVIDIA ↗) coming soon. First open omnimodel that generates text, image, video, audio, and action jointly. (NVIDIA Newsroom | eWeek)
Gemini 3.5 Pro approaching (Jun 6 reporting) Infra — Not yet released: Google confirmed at I/O (May 19) it would ship "next month." TechTimes reports it's targeting a 2-million-token context windowHow much text a model can see and use at once while writing a reply.Anthropic ↗ and a new "Deep Think" reasoning mode. Prediction markets price in late June. No firm date; do not block any work on it. (TechTimes)

Anthropic: claude-sonnet-4-0 and claude-opus-4-0 retired June 15 — Announced April 14; confirmed. After June 15 these versioned model identifiers return API errors. Recommended replacements: claude-sonnet-4-5 (same tier, larger context) or claude-opus-4-7 (stronger, same or lower cost for many workloads). Note: this is separate from the Agent SDK credit-pool change also landing June 15 — two distinct Anthropic changes on the same date. (Anthropic docs | endoflife.date/claude)

ChatGPT crosses 1 billion monthly active users (Jun 2–3) Trending — Reached the milestone faster than Google Search (10 yrs), Facebook (8 yrs), Instagram (6 yrs), and TikTok. Figures are Sensor Tower estimates of app MAU (not an audited OpenAI disclosure). Claude sits at 56M MAU but is growing 640% YoY vs. ChatGPT's 62%. (The Next Web | US News)
BYD enters humanoid robotics (Jun 3–4) Robotics/IoT — China's largest EV maker confirmed it is developing humanoid robots under project codename "Yao-Shun-Yu," leveraging its battery, sensor, and software supply chain. If it reaches commercial scale, BYD intends to distribute through its ~10,000-dealer network — a distribution channel no dedicated robotics startup can match. (Car News China | eWeek)

Claude second global outage in 4 days (Jun 5) Infra — All models (Opus 4.5 through Opus 4.8), claude.ai, Claude Code, and Cowork showed elevated errors starting 8:08 PT. Recovery was staggered by model, with Opus 4.5 last to recover at 10:29 PT (18:29 UTC). Root cause cited as infrastructure (not security); no data exposure confirmed. With two incidents in one week, this is raising internal conversation at engineering teams about whether AI workflows now qualify as critical infrastructure requiring SLA and fallback planning.

Colorado AI Act effectively delayed to January 1, 2027 (May 14) Policy — The original SB 24-205 June 30, 2026 compliance deadline is no longer in effect: Governor Polis signed SB 189 on May 14, replacing the original law with a narrower framework and pushing the effective date to January 1, 2027. The new law drops the risk-management program and algorithmic-discrimination-impact-assessment requirements; what remains is consumer notice before AI-assisted decisions, adverse-decision notices with appeal rights, and developer documentation requirements. If your team was mid-sprint on Colorado Act compliance work, you have breathing room — but check with counsel on which requirements carried over. (Hunton | Colorado General Assembly SB 189)
