By default the plugin prettifies discovered ids into display names. This PR allows to display LiteLLM's model_list aliases through a new setting named formatModelNames boolean (default true). An explicit false uses the raw /v1/models id as the display name; any other value keeps the default so a typo can't silently disable formatting.

Summary by CodeRabbit

  • New Features
    • Added a formatModelNames option to control how discovered model names appear in the picker.
    • By default, model IDs are formatted for display; setting the option to false shows the original IDs.
    • Per-model name overrides remain supported.
    • Changing this option refreshes model discovery to keep cached results accurate.

By default the plugin prettifies discovered ids into display names
(`anthropic/claude-3-5-sonnet` -> "Claude 3.5 Sonnet"). Some users want
the picker to mirror their LiteLLM `model_list` aliases verbatim, so add
a per-provider `formatModelNames` boolean (default `true`). An explicit
`false` uses the raw `/v1/models` id as the display name; any other
value keeps the default so a typo can't silently disable formatting.

The choice is threaded through discovery and the background refresh
context, and folded into the cache key since display names are baked
into cached entries. Default configs keep the plain key so existing
caches stay warm after upgrading.

📝 Walkthrough

Walkthrough

The plugin adds formatModelNames, which defaults to formatted model names and uses raw model IDs when explicitly set to false. The setting passes through discovery and refresh, affects cache identity, and is documented and tested.

Changes

Model naming configuration

Layer / File(s) Summary
Naming option through discovery
src/plugin/index.ts, test/to-config-model.test.ts, README.md, CHANGELOG.md
The provider option defaults to formatting and passes through discovery and refresh. Model conversion selects a formatted name or the raw model ID. Tests and documentation cover the option.
Cache identity and validation
src/utils/model-cache.ts, test/model-cache.test.ts
Cache keys distinguish formatModelNames: false while preserving existing keys when the option is enabled or omitted. Tests cover the setting with and without model filters.

Export toConfigModel and assert the display name is the prettified id by
default and the raw /v1/models id when formatModelNames is false, and that
non-chat models stay hidden either way.
