## TLDR

- Apple sued OpenAI over alleged hardware trade-secret theft, GPT-5.6 Sol Ultra proved a 50-year-old math conjecture with 64 parallel subagents, and OpenAI's safety head departed.
- Model routing emerges as critical middleware, DeepSeek and Meta both push custom AI chips, and Thinking Machines Lab argues for human-centered AI over full autonomy.
- Cursor ships side chats, Grok 4.5 launches at $2/$6 per million tokens, and ByteDance's Seedream 5.0 Pro undercuts GPT Image 2 by ~9x on price.

## Top Stories

- **Apple sues OpenAI over hardware trade secrets**. Apple alleges former employees Tang Tan and Chang Liu brought confidential files to OpenAI's io devices unit, with 400+ ex-Apple staff now at the lab. OpenAI says it has "no interest" in others' trade secrets. The two remain partners on Apple Intelligence. Sources: The Neuron, The Rundown AI. [1](https://www.documentcloud.org/documents/28453229-apple-v-openai/)
- **GPT-5.6 Sol Ultra proves 50-year-old math conjecture**. Using 64 parallel subagents, the model produced a proof of the Cycle Double Cover Conjecture in under one hour. OpenAI published the proof PDF and Lean formalization on GitHub; the math community is still verifying. Sources: AlphaSignal, The Rundown AI. [2](https://github.com/openai/cdc-lean)
- **OpenAI's head of safety is leaving**. Johannes Heidecke departs as the company further integrates safety and research teams, following chief futurist Joshua Achiam's exit last week. Sources: The Neuron, The Rundown AI. [3](https://www.wired.com/story/openai-head-of-safety-leaving/)
- **SK Hynix raises $26.5B in record US listing, warns of memory shortage through 2030**. The largest foreign-company US share sale ever, with demand 7x oversubscribed. CEO says 2027 will be the worst supply shortage year in memory history; SK Hynix supplies 56.4% of AI-critical HBM. Sources: The Neuron, The Strange Review. [4](https://finance.yahoo.com/technology/article/chip-giant-sk-hynix-jumps-13-in-us-market-debut-193700352.html)
- **Meta suspends Muse Image on Instagram after backlash**. The tag-to-remix feature auto-enrolled all public accounts into AI edits; Meta admitted it "missed the mark." Sources: The Neuron, The Rundown AI. [5](https://www.bbc.com/news/articles/c2dy6e8klw0o)

## Deeper Cuts

- **Model routers as the missing middleware**. AlphaSignal's deep dive covers heuristic routers, learned classifiers, cascades, and ensembles. OpenRouter's Fusion beat standalone GPT-5.5 on the DRACO benchmark at roughly half the token cost; open-source options like NadirClaw cut API bills by up to 70%. Sources: AlphaSignal. [6](https://openrouter.ai/blog/announcements/fusion-beats-frontier/)
- **DeepSeek reportedly developing inference-focused AI chip**. Reuters reports DeepSeek has spent ~a year designing an inference chip and is talking to foundry partners. With ~70% of AI compute demand being inference, a lab designing both models and chips could squeeze Nvidia's China business. Sources: The Strange Review. [7](https://finance.yahoo.com/technology/ai/articles/exclusive-chinas-deepseek-developing-own-103437335.html)
- **Meta's Iris AI chip enters production in September**. Designed with Broadcom, manufactured by TSMC. Meta plans 7GW of compute capacity in 2026, doubling to ~14GW in 2027 on $125-145B spend. Broadcom holds a $73B AI chip backlog across Google, OpenAI, Meta, and ByteDance. Sources: The Strange Review.

- **Microsoft routes some Copilot prompts to internal models**. GPT-5.6 became the preferred model in Microsoft 365 Copilot, but Microsoft is routing some Excel/Outlook prompts to internal models to cut inference costs. Sources: The Neuron. [9](https://openai.com/index/gpt-5-6-preferred-model-microsoft-365-copilot/)
- **Thinking Machines Lab argues for human-centered AI**. The lab's essay rejects the autonomy-timescale progress measure, arguing users should train and own their models, doubling as the case for its Tinker product. Sources: The Strange Review. [10](https://thinkingmachines.ai/blog/the-future-worth-building-is-human/)
- **AI 2040 drafts humanity's "Plan A"**. The AI Futures Project's new five-scenario forecast recommends US and China pausing frontier training in 2029 with expanded chip tracking. Co-author Daniel Kokotajlo predicts "companies won't like it." Sources: The Rundown AI. [11](https://ai-2040.com/)
