Steel Bank Common Lisp version 2.6.7 releases with interactive manual documentation in docstrings and expanded ARM64 and AVX512 SIMD support

Steel Bank Common Lisp (SBCL) 2.6.7 introduces the new `SB-MANUAL` contrib module, allowing the SBCL manual to be explored interactively via docstrings in development environments like SLIME and MGL-PAX. This release also adds ARM64 support to `SB-SIMD`, enables AVX512 instructions on X86-64, improves `INTEGER-LENGTH` performance on MIPS and LoongArch, and delivers multiple compiler bug fixes.

// ANALYSIS

SBCL remains the powerhouse of high-performance Common Lisp, continuously blending modern CPU instruction set support with interactive development capabilities.

–**Interactive In-REPL Documentation:** The new `SB-MANUAL` contrib module makes the complete documentation navigable inside code editors via standard definition lookup (`M-.`).
–**Modern Hardware Optimization:** Gaining ARM64 SIMD support alongside X86-64 AVX512 instruction capabilities ensures Lisp code can leverage modern CPU vector operations efficiently.
–**Robust Multi-Arch Maintenance:** Bug fixes for ARM64 miscompilations and non-loop `INTEGER-LENGTH` routines for MIPS and LoongArch reflect active cross-architecture care.

David Ha runs K3 locally on M5 Max

AI researcher David Ha (@hardmaru) shared an experiment running the massive K3 language model locally on Apple's M5 Max chip. Operating at a throughput of approximately 0.3 tokens per second, the test demonstrates the capability of high-capacity Apple Silicon unified memory to host huge models, even if the current performance is exceptionally slow.

OpenAI open-sources Codex Security CLI

OpenAI has open-sourced Codex Security CLI, a tool designed to help developers discover, validate, and remediate vulnerabilities directly within their local development environment and CI/CD pipelines. By combining local context analysis with AI threat modeling, Codex Security CLI allows engineering teams to scan local repositories, automate security checks in workflows like GitHub Actions, and track security findings over time.
