AI Inference Startup Raises $300M, C919 Faces Technical Issues, and US May Ban Chinese AI Models

Key Takeaways

1. An AI inference company secured $300M in Series C funding at a $10.3B valuation, accelerating infrastructure expansion.
2. A leaked internal complaint from China Southern Airlines reveals repeated failures on two new C919 aircraft, demanding fixes from COMAC.
3. US may soon permanently ban the use of Chinese AI models, citing Moonshot AI's distillation of Anthropic's model as a precedent.
4. Investigative reporting exposes reform schools for internet addiction rebranding as "quality education bases," using control tactics to discipline minors.
5. @levelsio shared practical tutorials on building a personal AI server with Hetzner VPS and using Claude Code to create a calorie tracking app.
6. Tw93's Pake now supports AI agents with stable JSON output and local build, installable as a skill for Claude Code users.

1. AI Infrastructure and Agent Tools

2. @levelsio built Caltrack, a calorie tracking app and Telegram bot using Claude Code, integrating WHOOP and WIP to analyze the correlation between sleep and recovery, targeting body fat reduction. — via 1
3. @levelsio published a step-by-step tutorial on setting up a personal AI server using Hetzner VPS, Tailscale, and Claude Code. — via 1 2
4. AI agents can now directly use Pake, supporting --json for stable JSON output and --config for app description; Claude Code users can install Pake as a skill for local builds without a server. — via 1

2. China Tech and Policy Risks

1. @levelsio predicted that the US may soon permanently ban any person or company from using Chinese AI models, citing the Moonshot AI distillation incident involving Anthropic's model as a warning sign (disputed/unverified). — via 1
2. A leaked internal complaint from China Southern Airlines reported multiple recurring failures on two newly delivered C919 aircraft, urging COMAC to "conceal nothing" and submit a rectification plan. — via 1

3. Social Investigations and Controversies

1. An investigative report revealed that after policy tightening, many internet addiction reform schools rebranded as "quality education bases" to continue operations; they use methods including communication cuts, sleep control, forced kneeling, and humiliation to make minors obedient, forming a profit chain involving parents, short-video platforms, and institutions. — via 1
2. Shenzhen Metro spent approximately 38 million yuan ($5.2M) on 945 smart security gates (about 40,000 yuan each), raising concerns over high costs and severe congestion during peak hours, coinciding with tightened security measures. — via 1 2
