# Changelog v0.1.81 - 2026-02-27

### Added

- **Dynamic OpenRouter free model discovery** -- fetches live free models from OpenRouter API at startup; replaces static list with fresh data so new free models appear automatically without code updates. Falls back to cached static list with a yellow warning on network failure.
- **`formatCtxWindow` and `labelFromId` utility functions** -- extracted to `lib/utils.js` for testability; used by dynamic OpenRouter discovery to convert API data to display format.
- **16 new unit tests** -- covering `formatCtxWindow`, `labelFromId`, and MODELS array mutation logic (147 total tests across 23 suites).
- **NVIDIA NIM auto-configuration** -- selecting a NIM model in OpenCode now auto-creates the nvidia provider block in `opencode.json` if missing, eliminating the manual install prompt.

### Fixed

- **Auto-update infinite loop** -- when running from source (dev mode with `.git` directory), auto-update is now skipped to prevent the restart loop where LOCAL_VERSION never changes.
- **NVIDIA model double-prefix bug** -- model IDs in `sources.js` already include `nvidia/` prefix; `getOpenCodeModelId()` now strips it for nvidia provider (like it does for zai), preventing `nvidia/nvidia/...` in OpenCode config.

### Removed

- **`checkNvidiaNimConfig()` function** -- replaced by auto-create pattern; dead code removed.
