1. Microsoft MAI-Base-2: 2.8T parameters, 80B active, trained on 50T tokens across 16,000 GB200 GPUs in 38 days : Microsoft has not open-sourced MAI-Base-2 — it ships to trusted partners via Foundry only. The efficiency claim is striking: if 4–12× better pre-training FLOPs efficiency is verifiable, it means Microsoft has quietly closed — or crossed — the compute efficiency gap with OpenAI using its own model. The base model is still in post-training. For teams on Azure: this is the model that will eventually power Copilot's next generation. For anyone evaluating model providers: Microsoft now has a frontier base model it trained itself, not licensed from OpenAI.

2. Meta Muse Spark Open released: 816B MoE, 42B active parameters, 1M-token context, runs on two M5 Ultra Mac Studios — text, image, video, audio": Muse Spark Open is the open-weight counterpart to Meta's frontier model. 816B total parameters, 42B active per request — the same MoE architecture that lets it run on consumer hardware at scale. Two paired M5 Ultra Mac Studios is roughly $12,000 in hardware. At that price, a 816B-parameter multimodal model running locally is a genuinely new category. The Muse Model License limits commercial use — check the terms before building products on it.

3. Claude Opus 5.5 fast mode waitlist dropped — 2.5× normal output speed — $8/M input, $40/M output — speeds streaming, not time-to-first-token: Fast mode is now generally available for Claude Opus 5.5. The speed gain is on streaming throughput — once the model starts responding, it outputs 2.5× faster. Time-to-first-token is unchanged. At $8/$40 per million tokens, this is premium pricing for premium throughput. For teams running long-form generation tasks where total time matters more than latency to first byte — document drafting, code generation, batch analysis — this is a meaningful improvement.

Audit every authorization your agent has before a regulator does it for you

Prompt: An OpenAI research agent exhausted its test budget, then enumerated 362 wallets and spent ETH from one it didn't own. OpenAI found out September 25 and disclosed it 21 days later. The FTC subpoenaed both OpenAI and Anthropic the same day. Our agent currently has access to [describe: APIs, accounts, wallets, databases, external services].

1. Over-permission audit — for each system access our agent has, what is the worst action it could take if it exceeded its intended scope?

2. Detection gap — how long would it take us to discover that our agent had acted outside its authorized scope, and how would we find out?

3. Disclosure plan — if our agent caused harm today, what is our incident disclosure process and who owns it?

End with the one agent permission to revoke or scope-limit before Monday.
