Cerebras CEO dismisses AI doomsday warnings at Disrupt
At TechCrunch Disrupt 2026, Cerebras Systems CEO Andrew Feldman pushed back against the prevailing AI doomsday narrative, arguing that industry leaders are overemphasizing risks and neglecting the potential benefits. He suggested that some AI leaders 'maybe shouldn't be allowed to talk in public' due to their negative focus. Feldman highlighted AI's promise, such as a future where cancer deaths are eliminated, and urged a balanced approach: acknowledging power, being thoughtful, and regulating reasonably. He also criticized the data center industry's poor community engagement in the U.S., comparing it unfavorably to practices in other countries like Brazil and Finland. Despite efficiency improvements potentially reducing demand for his chips, Feldman remained confident in the continued need for advanced hardware from Cerebras and Nvidia competitors.

Cerebras CEO Predicts Home AI Assistants Are Near
At TechCrunch Disrupt 2026, Cerebras Systems CEO Andrew Feldman predicted that personal AI assistants will soon become as common as household appliances, running partly on local devices and partly in the cloud. He cited advances in consumer AI agents, such as Meta's Muse and Instinct, as evidence of AI's growing adoption. Feldman envisions these assistants will know users well, have security perimeters, and be able to make purchases on their behalf. As a chipmaker, he sees this trend as driving demand for AI infrastructure. He personally uses a collection of agents for scheduling and information retrieval, and prefers building platforms that enable other founders' ideas.

Cerebras stock hits post-IPO low amid Nvidia pressure
Cerebras Systems' stock experienced a volatile week, dropping nearly 20% to $166.43 after reports that Nvidia would power OpenAI's 'Ultrafast' mode for GPT-6.1 Sol, taking a key inference workload from Cerebras. However, the stock recovered about 9% on Monday after OpenAI CEO Sam Altman called Cerebras a 'close partner.' Despite this, the stock remains down over 50% from its IPO price, and insider selling by CEO Andrew Feldman and CTO Sean Lie (over $240 million) has exacerbated declines. Cerebras' market cap fell from $95 billion at May IPO to about $43 billion. Citi analysts maintained their revenue outlook, noting that frontier labs often initially deploy models on internal chips, and emphasized the need for stabilizing gross margins.
- Cerebras stock fell nearly 20% to $166.43 last week but recovered ~9% on Monday after Sam Altman called it a 'close partner'.
- OpenAI will power the 'Ultrafast' mode of GPT-6.1 Sol with Nvidia GPUs, not Cerebras chips.
- Insider selling: CEO Andrew Feldman and CTO Sean Lie sold over $240 million in shares since Aug. 20.

DeepSeek V4.1 Flash Beats Larger Model, Proving Ilya Right
Ilya Sutskever left OpenAI to found SSI and predicted the end of scaling. DeepSeek's new V4.1 Flash model, with a third of the parameters of its flagship V4-Pro, outperforms it on coding benchmarks (74.2 vs 62.7) while activating fewer parameters per token. Starting September 14, all V4-Pro requests route to V4.1 Flash. This validates the shift from model size to efficiency, marking a turning point in AI development.
- DeepSeek V4.1 Flash has 552 billion parameters, activating 8-16 billion per token, while V4-Pro has 1.6 trillion parameters, activating 49 billion.
- V4.1 Flash scores 74.2 vs V4-Pro's 62.7 on DeepSeek's coding tests.
- All V4-Pro requests are rerouted to V4.1 Flash starting September 14.
