openai-params

Combined OpenAI fast-mode and verbosity settings for pi.

What it does

This extension adds /openai-params, which opens a small settings screen for:

• Ctrl+S saves
• Esc cancels

Use the list to:

• toggling fast mode
• setting verbosity to low, medium, high, or the default unset state

When enabled, it patches provider requests right before send:

• fast mode → service_tier=priority
• verbosity → text.verbosity=<level>

Behavior

• Fast mode is only applied to configured supported models.
• Default supported models are:
  • openai/gpt-5.4
  • openai-codex/gpt-5.4
• Verbosity is applied only to OpenAI Responses-family APIs:
  • openai-responses
  • openai-codex-responses
  • azure-openai-responses
• The default verbosity setting is unset, so the extension does not send any text.verbosity field unless you choose one.

Config

Config uses the same project-over-global pattern as the fast-mode package:

• project: .pi/extensions/openai-params.json
• global: ~/.pi/agent/openai-params.json

If neither file exists, the extension creates the global file on first run.

Default config:

{
  "fast": false,
  "verbosity": null,
  "supportedModels": [
    "openai/gpt-5.4",
    "openai-codex/gpt-5.4"
  ]
}

Integration

This extension emits its current state on pi's extension event bus over pi:openai-params with:

• source
• cwd
• fast
• verbosity

That lets other extensions, including status, show the active non-default fast/verbosity settings for the current workspace.

Notes

This extension combines the behavior of:

• @benvargas/pi-openai-fast for service_tier=priority
• pi-verbosity-control for text.verbosity

based on OpenAI GPT-5 / Responses API parameter docs.
