pi-gpt-config

wezterm-gui_yELqYVWQ4Y.mp4

Adds a /gpt-config command to pi for Codex-parity settings on three models only:

• gpt-5.3-codex
• gpt-5.4
• gpt-5.4-mini

Outside those three models, every setting in this extension is a no-op.

Install

pi install git:github.com/edxeth/pi-gpt-config

Controls

• Fast mode: on, off (only shown for gpt-5.3-codex and gpt-5.4)
• Personality: none, friendly, pragmatic, claude
• Verbosity: low, medium, high
• Reasoning summary: none, auto, concise, detailed
• Footer: show, hide

Behavior

• Fast mode requests OpenAI priority service tier on models that support it.
• Personality is the only prompt-bearing mode:
  • none: model's built-in Codex tone with no extra overlay
  • friendly: warmer, more collaborative
  • pragmatic: more direct, factual, compact
  • claude: Claude-inspired answer-first, terse, lower-overengineering, lower-check-in behavior
• Non-none personalities are re-injected on every model request, so they add repeated prompt-token cost.
• Verbosity controls answer length.
• Reasoning summary controls whether a summarized reasoning trace is requested back from the API. It does not disable internal reasoning.

Defaults on parity models

• Fast mode: off on models that support priority service tier
• Personality: none
• Verbosity: medium
• Reasoning summary: auto
• Footer: show

Command

Open the panel:

/gpt-config

Subcommands:

/gpt-config status
/gpt-config reset
/gpt-config fast on
/gpt-config fast off
/gpt-config personality none
/gpt-config personality friendly
/gpt-config personality pragmatic
/gpt-config personality claude
/gpt-config verbosity low
/gpt-config verbosity medium
/gpt-config verbosity high
/gpt-config summary none
/gpt-config summary auto
/gpt-config summary concise
/gpt-config summary detailed
/gpt-config footer show
/gpt-config footer hide

Persistence

State is stored globally in settings.json under the gptConfig namespace:

~/.pi/agent/settings.json

If PI_CODING_AGENT_DIR is set:

$PI_CODING_AGENT_DIR/settings.json

Persisted shape:

{
  "gptConfig": {
    "fastMode": false,
    "personality": "none",
    "verbosity": "medium",
    "summary": "auto",
    "showFooter": true
  }
}

Legacy state from ~/.pi/agent/cache/pi-gpt-config/state.json is migrated on load.

TUI

• The panel explains what each setting does.
• The panel hides Fast mode on gpt-5.4-mini.
• The footer shows:
  • priority and personality on gpt-5.3-codex and gpt-5.4
  • personality only on gpt-5.4-mini
• The footer is only shown on the three parity models.

Notes

• This extension mixes native API controls (service_tier, text.verbosity, reasoning.summary) with a single prompt overlay mode (personality). gpt-5.4-mini gets the verbosity/summary/personality behavior but not service_tier.
• personality=none means no extra prompt overlay.
• personality=claude is a Claude-inspired prompt overlay, not provider-native Claude mode or true Claude parity.
• The Claude overlay also counter-pressures Codex-style optional check-ins by preferring autonomous continuation until a real blocker or decision appears.
• Backend support still depends on the upstream provider honoring the request fields.
