pi-model-selector-x

ModelSelectorX enhances pi's native /model selector with a detail pane showing context window, cost, input modalities, API protocol, and reasoning capability.

It patches the built-in /model view.

WARNING

This extension patches the /model internals and could break if pi updates in an incompatible way. I chose this approach rather than re-implementing the internal model selector rendering so that it would automatically update the rendering.

Features

• Bottom detail pane for the selected model showing full metadata
• Context window size (e.g. 200k, 1M)
• Max output tokens
• API protocol (resp / comp / anth)
• Input modalities (txt, txt+img, txt+img+aud)
• Reasoning capability indicator
• Cost breakdown (input / output / cache read / cache write)
• Free model detection

Detail Pane

The detail pane appears below the model list and shows:

| Field | Source | Example | |-------|--------|---------| | Context | model.contextWindow | 200k | | Max Output | model.maxTokens | 64k | | Protocol | model.api | resp / comp / anth | | Input | model.input | txt+img / txt | | Reasoning | model.reasoning | ⚡ reasoning | | Cost | model.cost | $2.50 / $15.00 / free | | Cache | model.cost.cacheRead/Write | $0.25 |

Protocol abbreviations

| Short | Full | |-------|------| | resp | OpenAI Responses API | | comp | OpenAI Completions API | | anth | Anthropic Messages API |

Installation

npm

pi install npm:pi-model-selector-x

To try it for one run without adding it to your settings:

pi -e npm:pi-model-selector-x

git

pi install git:github.com/Dwsy/pi-model-selector-x

Usage

After installation, open the model selector with the built-in keybinding or:

/model

Notes

• Tested with pi 0.70.2
• ModelSelectorX patches the native /model path, so the built-in slash command and model hotkey keep using pi's own navigation and selection flow.
• ModelSelectorX relies on private model-selector internals, so upstream pi changes may require ModelSelectorX updates.
