ALPHABET
Alphabet suffers worst trading day in company history
The Yuzu Squeeze: Alphabet shares just dropped 13% on Thursday, their steepest one-day fall since Google's 2004 IPO, erasing roughly $500 billion in market value after a disappointing earnings call.
The details:
- Alphabet reported negative free cash flow of $9.07 billion in Q3, far worse than the $2.7 billion shortfall analysts had expected.
- The company kept its full-year capex guidance at $195 billion to $205 billion despite the cash flow miss.
- Search advertising revenue grew 12% to $63.35 billion but missed analyst expectations, partly due to lower AI Mode monetization.
- Microsoft, by contrast, traded flat after reporting $45.2 billion in capex (up 30% YoY) and $18.63 billion in free cash flow, down 27% but still positive.
Why it matters: Investors are scrutinizing whether heavy AI infrastructure spending is paying off, and Alphabet's "messy" earnings call raised doubts about Google's AI Mode monetization versus ChatGPT and Claude. One analyst still sees Google's 4 billion search users as a long-term edge.
MISTRAL
Mistral open-sources trillion-parameter "Le Chonk" model
The Yuzu Squeeze: Mistral just released the weights for its trillion-parameter open-source model Mistral Large 4, nicknamed "Le Chonk," letting businesses and governments deploy it themselves for cybersecurity defense.
The details:
- ML4 matches Chinese open-weight rival GLM-5.3 in performance while using 47% fewer tokens per task, Mistral says.
- The model ranks first among open models on Artificial Analysis' Coding Agent Index for agentic coding tasks, according to Mistral.
- Weights are available on Hugging Face and via API, letting organizations deploy ML4 on-prem for sovereign cyber defense.
- CEO Arthur Mensch said AI should "be a tool for empowerment, not dominance," positioning ML4 against closed rivals like OpenAI and Anthropic.
Why it matters: Open-weighting a trillion-parameter model gives governments and enterprises AI access that "can't be cut off," per VP of Science Pierre Stock, sharpening the fight between open and closed AI providers in cybersecurity use cases.
Why it matters for Asia: GLM-5.3, Mistral's named benchmark, underscores how Chinese open-weight models remain the standard open AI developers must beat.
