Show HN: Osaurus – Ollama-Compatible Runtime for Apple Foundation Models Osaurus is an open-source local inference runtime for macOS, written in Swift and optimized for Apple Silicon.

It lets you run Apple Foundation Models locally β€” fully accelerated by the Neural Engine β€” while also exposing OpenAI- and Ollama-compatible endpoints, so you can connect your favorite apps, tools, or clients without any code changes.

Key points:

* Supports Apple Foundation Models natively

* Compatible with OpenAI & Ollama APIs

* ~7 MB binary, runs locally (no cloud, no telemetry)

* MIT Licensed, open source

We’re exploring what a local-first AI ecosystem could look like β€” where inference, privacy, and creativity all happen on your own hardware. Feedback and testing welcome!

Show HN: A terminal spreadsheet editor with Vim keybindings While speccing out this spreadsheet tool, I realized that I never had to think about the keybindings. It all just came naturally from Vim. Normal&#x2F;insert&#x2F;visual modes, hjkl navigation, dd&#x2F;yy&#x2F;p, :w, :q. The usual muscle memory works.<p>It supports CSV&#x2F;TSV import and export, and a native .cell format that preserves formulas. The formula engine handles SUM, AVERAGE, COUNT, MIN, MAX, and IF with range references.<p>The codebase is a Cargo workspace: a pure cell-sheet-core library (no TUI dependency) and a cell-sheet-tui crate on top of ratatui. Early days, but it&#x27;s usable.<p>To try it out: cargo install cell-sheet-tui<p>Feedback of any kind is greatly appreciated!
