Best to Build With Today
* Coding — claude-opus-4-6-thinking (Top-ranked for multi-file refactors).
* Reasoning — gemini-3.1-pro (The new leader for logic and math).
* Chat — gemini-3.1-pro (Highest Arena Elo for general assistant tasks).
* Video generation — MiniMax-H3 (Best open-weights choice for 2K video + audio).
* Value pick — DeepSeek V4-Flash (Unbeatable at $0.18 per 1M tokens).

OpenAI Astra Solves 10 Major Math Problems
OpenAI used an internal Astra model to solve 10 previously unsolved problems in number theory and combinatorics. By hooking a chain-of-thought verifier up to the Lean theorem prover, it hit 40% better formal verification than GPT-4o.
* Why it matters: AI is making the jump from "creative writer" to "autonomous scientific researcher."

Alibaba Qwen3.8-Max Hits #2 on Arena
Qwen3.8-Max — 2.4T parameters, MoE architecture, trained on 15T tokens with a heavy focus on multilingual and code-heavy data — has stormed the Chatbot Arena with a 1496 Elo score.
* Why it matters: Proprietary-grade performance is no longer a US monopoly.

DeepSeek V4-Flash Price Disruption
95% of GPT-4o performance at 1/10th the cost — $0.18/1M tokens. It's quickly becoming the go-to for high-throughput, agentic workflows.
* Why it matters: The economics of running agents just got 10x cheaper.

💼 Industry & Business
Anthropic's Culture Concerns
Dario Amodei is flagging a real tension: as Anthropic scales fast, some of the incoming talent seems more interested in the paycheck than the Constitutional AI safety mission.
* Why it matters: Keeping a research-first culture intact is arguably the hardest part of growing a lab into a giant.

The 'Build vs. Buy' Flip
Chamath Palihapitiya's argument is simple: AI-assisted coding has made building custom internal tools easier — and cheaper — than buying bloated, inflexible SaaS.
* Why it matters: Traditional enterprise software vendors are staring down an existential threat.

Tesla FSD Data Flywheel
Tesla's FSD fleet just crossed 13 billion miles, adding 3 billion of those in just 90 days.
* Why it matters: The real-world data advantage is compounding faster than anyone else can match.
