Rewriting Bun in Rust

TLDR 1 week ago

Bun, a JavaScript runtime that processes 22 million monthly downloads, is being rewritten from Zig to Rust to systematically prevent memory safety bugs rather than fixing them one-by-one. The rewrite was completed in 11 days using Claude Code with approximately 50 dynamic workflows that mechanically ported 535,496 lines of Zig code while maintaining the existing test suite. This shift gives the Rust compiler the ability to catch use-after-free, double-free, and memory leak errors at compile time rather than relying on code review and runtime tools like address sanitizer.

[AINews] SpaceXAI launches Grok 4.5, first Opus-class model post Cursor acquisition

Latent Space 1 week ago

SpaceX's xAI launched Grok 4.5, a coding-focused frontier model developed in partnership with Cursor, positioned for cost-efficiency and speed rather than benchmark supremacy. The model costs $2 per million input tokens and $6 per million output tokens, with a 1.5 trillion parameter size that is 3 times larger than its predecessor Grok 4.3. Grok 4.5 becomes available immediately across Grok Build, the Cursor IDE, and various API platforms, competing directly with Anthropic's Opus and OpenAI's GPT models in the coding-agent workflow market.
