OpenAI shipped an entire model family in three days. DeepSeek is about to drop a trillion-parameter open-weight challenger built on Chinese silicon. Google's AI is solving open math problems autonomously.
And the hyperscalers are all racing to break free from Nvidia's grip with custom chips.
Meanwhile, the talent wars are intensifying — Alibaba lost its most important AI researcher and replaced him with a Google DeepMind veteran within 48 hours.
Here's what matters from the last few days, stripped to signal only.

OpenAI ships three model tiers in 72 hours
GPT-5.3 Instant landed March 3 — 26.8% fewer hallucinations on web queries, plus a tone overhaul addressing what OpenAI called "cringe" behavior. Within an hour they teased GPT-5.4, which launched today with upgrades to reasoning, coding, tool use, and native computer control. GPT-5.4 Pro and GPT-5.4 Thinking shipped alongside it. The rapid-fire cadence comes as ChatGPT uninstalls surged 295% after the Pentagon deal and Claude briefly hit #1 on the US App Store.

DeepSeek V4 — trillion-parameter multimodal model imminent
V4 is expected this week — 1T total parameters, 32B active per token, native text/image/video generation, and a 1M-token context window. Built on Huawei and Cambricon chips with Nvidia and AMD deliberately excluded. One benchmark: 50,000 daily financial doc classifications cost $210/month on V4 versus $4,200 on GPT-5, accuracy within 2 points. Anthropic has accused DeepSeek of industrial-scale distillation — 16M exchanges through 24,000 fraudulent accounts.

Google DeepMind — Gemini 3.1 Flash Lite + Deep Think breakthroughs
Gemini 3.1 Flash Lite shipped March 3 for high-volume, cost-efficient inference. Separately, Gemini Deep Think scored 90% on IMO-ProofBench Advanced, autonomously solved four open problems on Bloom's Erdős Conjectures database, and contributed to an ICLR 2026 paper — with the "Aletheia" variant achieving better reasoning at lower compute. Google Research also published breakthroughs on March 4 including Earth AI (geospatial models covering floods, wildfires, and air quality across 100 countries) and DeepSomatic, an open-source AI tool for identifying cancer genetic variants.

Alibaba's Qwen team — leadership exodus after Qwen 3.5 launch
Key researchers including tech lead Junyang Lin departed within 24 hours of shipping the Qwen 3.5 small model series. Alibaba quickly hired Google DeepMind's Zhou Hao (Gemini 3, AI Mode, Deep Research) as head of post-training research. The 90,000+ enterprises on Qwen now face the risk that future flagships move behind proprietary APIs.

JetStream Security — $34M seed for AI governance
JetStream launched an AI governance platform built by veterans from CrowdStrike, SentinelOne, and Cohesity. Led by Redpoint Ventures with angels including the CEOs of CrowdStrike, Wiz, and Okta's co-founder. The core product: real-time "AI Blueprints" that map agent behavior, data access, tool calls, and costs across the enterprise — targeting MCP server sprawl and shadow AI.

AI market rotation — Broadcom surges, Nvidia wobbles, software rallies
Broadcom's Q1 earnings on March 4 triggered a sector rotation. CEO Hock Tan signaled AI chip demand trending toward 10 gigawatts of capacity with visibility into 2027, and confirmed Broadcom expects to deliver 3 gigawatts of inventory to Anthropic next year. Software stocks rallied hard — Salesforce +5%, ServiceNow +6.3%, CrowdStrike +3.7% — while Nvidia dipped 1.6% as investors questioned whether hardware dominance alone justifies the premium. Separately, OpenAI clinched an $840B valuation with its $110B mega-round from Amazon, SoftBank, and Nvidia — and Jensen Huang signaled he may scale back the originally announced $100B OpenAI investment.
