AI Daily Brief — 23 November 2025
Sunday spent in Opus 4.5 pre-launch silence. Claude Opus 4.5 confirmed for Mon Nov 24 (model id claude-opus-4-5-20251101). Claims SOTA on SWE-bench Verified ahead of Gemini 3 Pro and GPT-5.1; new pricing $5/$25 per Mtoken (3× cut from Opus 4.1’s $15/$75); agentic coding and computer-use upgrades; same-day public preview in GitHub Copilot + Microsoft Foundry. Weekly AI roundups frame Nov 17-23 as “pivotal week reshaping the industry”: Gemini 3 (Nov 18) + Microsoft/NVIDIA/Anthropic $45B three-way (Nov 18) + GPT-5.1-Codex-Max (Nov 19) + Olmo 3 (Nov 20) + Nano Banana Pro (Nov 20) + HunyuanVideo-1.5 (Nov 21) — one of densest release weeks of 2025. Quiet Sunday for open-source labs — no major new weights from Mistral, Qwen, DeepSeek, Meta, Cohere. Olmo 3 + HunyuanVideo-1.5 continued community uptake — derivative quantizations + ComfyUI workflows appearing through weekend. Anthropic Claude becomes only frontier model on all 3 major clouds from Mon’s Opus 4.5 launch: AWS Bedrock + Google Cloud Vertex + Microsoft Azure / Foundry. Strategic distribution edge over OpenAI (Azure-only at frontier) + Gemini (Google-only). Nano Banana Pro continues Workspace rollout from Nov 20 launch — Slides + Vids + Gemini app + NotebookLM; 2K/4K + web-grounded image gen + accurate multilingual text rendering.

Money, infra & hardware
No new rounds. Sunday spent processing the week’s $45B + 1 GW + 3-cloud-Claude reshaping of frontier-lab compute alignment.
Quiet corners
