Developer action required: Claude Sonnet 4 (claude-sonnet-4-20250514) and Claude Opus 4 (claude-opus-4-20250514) retire on the Claude API on June 15, 2026 - five days from now. Any production code with hardcoded model strings will return errors after June 15. Migrate to claude-sonnet-4-6 and claude-opus-4-8 today.
1. Claude API Deprecation - What Retires June 15 and What to Migrate To
Anthropic confirmed in its official release notes on platform.claude.com that two Claude models are being deprecated with API retirement on June 15, 2026:
| Retiring model string |
Retire date |
Migrate to |
Pricing change |
| claude-sonnet-4-20250514 |
June 15, 2026 |
claude-sonnet-4-6 |
Same tier pricing ($3/$15 per M tokens) |
| claude-opus-4-20250514 |
June 15, 2026 |
claude-opus-4-8 |
Same tier pricing ($5/$25 per M tokens) |
Separately, claude-opus-4-1-20250805 has also been deprecated with retirement on August 5, 2026 - that is a longer runway but worth noting for any code referencing the 4.1 model string. The recommended migrations are straightforward: claude-sonnet-4-6 is the current Sonnet tier and performs better than the original claude-sonnet-4 it replaced. Claude-opus-4-8 is the current flagship released May 28, 2026 with SWE-bench Pro at 69.2%, Dynamic Workflows in Claude Code, and 4x improved honesty over opus-4-7.
The migration is a search-and-replace in most codebases. If you are using the Anthropic Python or TypeScript SDK, the model string is typically in one place. If you are using a third-party framework that wraps Anthropic (LangChain, LlamaIndex, OpenClaw, etc.) check whether the framework has already updated its defaults - many have. The dangerous case is hardcoded model strings buried in configuration files or environment variables that are not in the main codebase. Check .env files, deployment configs, and infrastructure-as-code templates. For full Sonnet and Opus comparison see our Claude Code vs Codex comparison and ChatGPT vs Claude vs Grok 2026.
2. SpaceX Prices Tomorrow - Last Day for Retail Interest
The SpaceX investor roadshow concludes today. IPO pricing is expected after market close tomorrow, Wednesday June 11. SPCX begins trading on Nasdaq on Thursday June 12. The fixed price is $135/share - implying a $1.77 trillion valuation and a $75 billion raise, the largest IPO in history. Today is the last day to indicate interest via Robinhood, Fidelity, or Schwab for retail allocation. Allocation is not guaranteed at any level - demand reportedly exceeds supply at $135.
One confirmed structural detail that changes the usual lockup calculus: existing SpaceX shareholders including Musk are locked up for 366 days - one day longer than the standard 180-day lockup - limiting early insider selling but also capping the initial free float, which can amplify volatility in the first year of trading. Morningstar's formal valuation remains $780 billion vs the $1.77T IPO price. The AI infrastructure argument (Colossus generating $2.17B/month from Anthropic and Google) is the bull case.

3. WWDC Developer Week - What's Running Through June 12
Apple's WWDC developer week runs June 8-12 at Apple Park, with 100 video sessions, group labs, and one-on-one appointments with Apple engineers available through Friday. The keynote was Monday. The Platforms State of the Union (the deeper developer briefing) ran Monday afternoon. The remaining week covers the detailed technical sessions that tell developers exactly how to implement the new APIs.
The sessions most relevant to AI developers this week: the App Intents and SiriKit updates covering how apps can expose actions to Siri AI, the Foundation Models framework sessions covering the on-device model APIs available in iOS 27 / macOS Golden Gate, and the Machine Learning and AI track covering the updated Core ML and Create ML tools. All sessions are available on-demand at developer.apple.com after they air. Developer betas of iOS 27, macOS Golden Gate, and the other OS updates are available now at developer.apple.com. Full keynote recap: WWDC 2026 recap - Siri AI, macOS Golden Gate, iOS 27, and the EU exclusion.
