@pi-plugins/fast-mode

Request priority inference for selected models in pi with a session toggle.

Install

pi install npm:@pi-plugins/fast-mode

To try it for one session without changing your settings:

pi -e npm:@pi-plugins/fast-mode

Usage

Use /fast to control fast mode for the current session:

| Command | Action | | -------------- | ---------------------------------------------------------------------------- | | /fast | Toggle fast mode. | | /fast on | Enable fast mode. | | /fast off | Disable fast mode. | | /fast status | Show the current state and explain whether it applies to the selected model. |

To start a session with fast mode enabled:

pi --fast

Fast mode applies only to models listed in the configuration. Other models are left unchanged. A [fast mode] indicator appears above the editor while active.

Supported providers

| Provider | Pi provider | | ------------ | -------------- | | OpenAI | openai | | OpenAI Codex | openai-codex |

Priority availability depends on the provider and model.

Configuration

Optionally create <agent-dir>/extensions/fast-mode.json, typically ~/.pi/agent/extensions/fast-mode.json. The defaults are:

{
  "enabled": false,
  "models": [
    "openai/gpt-5.4",
    "openai/gpt-5.5",
    "openai/gpt-5.6-sol",
    "openai/gpt-5.6-terra",
    "openai/gpt-5.6-luna",
    "openai/gpt-6-astra",
    "openai/gpt-6-sol",
    "openai/gpt-6-luna",
    "openai/gpt-6.1-sol",
    "openai-codex/gpt-5.4",
    "openai-codex/gpt-5.5",
    "openai-codex/gpt-5.6-sol",
    "openai-codex/gpt-5.6-terra",
    "openai-codex/gpt-5.6-luna",
    "openai-codex/gpt-6-astra",
    "openai-codex/gpt-6-sol",
    "openai-codex/gpt-6-luna",
    "openai-codex/gpt-6.1-sol"
  ],
  "showStatus": true
}

| Setting | Description | | ------------ | ----------------------------------------------------------------------------------------------------------- | | enabled | Enable fast mode at session start. /fast changes only the current session and does not write to the file. | | models | The exact provider/model-id pairs fast mode applies to. | | showStatus | Show the status indicator while fast mode is active. |

Notes

Priority inference can cost more. Check your provider's pricing before enabling it.
