Good morning, I'm your host with the Ollama developer briefing for May 16th, 2026.
Daniel Hiltgen merged PR #15982, which speeds up release builds through several optimization strategies. The changes replace fixed parallelism with ninja's load targeting to prevent surge and stall behavior on build systems. Windows compression was adjusted from level 9 to 7 in 7zip, saving multiple minutes with minimal size impact. Linux builds now use zstd compression level 22 instead of 19, providing time savings while keeping CI growth minimal. Since the MLX component has grown too large, it's now packaged in separate archive files for Windows and Linux distributions. The pull request modified 10 files with 275 additions and 81 deletions.
Hiltgen also merged PR #16105, a smaller change that reduces verbose logging output in the key-value system. This modification touches the GGML Go file to quiet down what was described as "log spew."
Both changes focus on developer experience improvements - the first targeting build efficiency for releases, and the second cleaning up console output during development.
What's next: These optimizations should reduce release build times by several minutes and provide a cleaner development environment. The build system changes also benefit local developer builds, not just CI infrastructure.
That's your Ollama briefing for today. I'll be back tomorrow with more updates.
