Grant and Corey are conducting a live test of OpenAI's GPT-5.6 Sol model against Claude's Fable 5. The demonstration begins at 10am PT / 1pm ET and includes building a mini-app and refactoring code. The comparison will show how both models perform on practical development tasks.

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.

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.
