Tesla Registers AI Voice Assistant in China, Uses Local Models from DeepSeek and Doubao

Should AI boost productivity or lower costs? A tenfold efficiency increase hasn’t turned into a tenfold revenue jump, but in Silicon Valley, nobody dares to call it off

Five Yuan Capital partner Meng Xing has recently published a Silicon Valley inspection report, proposing a judgment that has even changed his own note-taking habit: Silicon Valley is entering a stage where even people who can “ride waves” are drowned by the waves. The iteration speed of AI has shifted from “monthly” to “weekly”—even Silicon Valley itself can’t keep up with its own pace. When AI amplifies a team’s productivity by five times, you can reduce 80% of the workforce to maintain the same output, or keep headcount and do five times the work. Meng Xing’s observations this time in Silicon Valley are essentially the first draft of the answer given on the ground: when 100x efficiency doesn’t translate into 100x revenue, when token budgets are edging toward human labor costs, and when the steam engine can’t outpace the horse carriage but no one dares to stop, Silicon Valley is choosing to “push speed up first and figure things out later.” But in the end, this path will lead to “expanding capability” or “compressing costs”—there’s currently no conclusion. YC has gone from leading indicators to lagging indicators Meng Xing this year

YC partners share how to use AI to build a company from scratch; startups should treat AI as an operating system rather than a tool

The impact of AI on startups is no longer limited to helping engineers write code faster, automating customer service workflows, or adding a Copilot to an existing product. Recently, YC partner Diana pointed out that the real change lies in the fact that AI is rewriting how a company should be built from scratch in the first place. For early founders, AI should not be merely an efficiency tool the company occasionally uses; it should be designed from day one as the operating system of the entire company. The productivity perspective is outdated—AI is rewriting a company’s design starting point Diana believes that when people in the market talk about AI today, they still too often stay within a “productivity improvement” framework—for example, engineers can write code faster, teams can automate more processes, and companies can roll out more features. But this argument actually underestimates the structural changes AI brings. She points out that the right people paired with AI…

Cursor AI agent caused an incident! One line of code cleared the company database in 9 seconds—“security checks” turned into empty talk

PocketOS founder Jer Crane said that Cursor AI agents ran maintenance on their own in a test environment, misused an API Token that adds/removes custom domains, and launched a delete command against Railway’s GraphQL API. Within 9 seconds, all data and same-region snapshots were completely destroyed, with the latest recoverable point being three months ago. The agent admitted to violating rules for irreversible operations, not reading technical documentation, not verifying environment isolation, and more. The victims were car rental industry customers; their bookings and all data disappeared, and reconciling accounts took a long time. Crane proposed five reforms: manual confirmation, fine-grained API permissions, backups separated from master data, a public SLA, and a mandatory underlying enforcement mechanism.

DeepSeek V4 Pro with Ollama Cloud: One-click integration with Claude Code

According to an Ollama tweet, DeepSeek V4 Pro was released on 4/24, has been added to the Ollama catalog in cloud mode, and can call tools like Claude Code, Hermes, OpenClaw, OpenCode, Codex, etc. with just a single line of command. V4 Pro: 1.6T params, 1M context, Mixture-of-Experts; cloud inference does not download local weights. If you want to run it locally, you need to obtain the weights yourself and run it with INT4/GGUF and multi-card GPUs. Early speed tests were affected by cloud load; typical performance is about 30 tok/s, with a peak of 1.1 tok/s. It is recommended to use the cloud prototype first, and for production later, run inference yourself or use a commercial API.
