README

@linioi/pi-fast-mode

npm version License: MIT

A pi extension that adds a protocol-aware /fast command with status indicator. It persists a local enabled flag in Pi's agent dir (fast-mode.json) and patches provider requests for supported targets:

  • openai-responses → service_tier: "priority"
  • openai-codex-responses → service_tier: "priority"
  • anthropic-messages with claude-opus-4-6 → speed: "fast" plus anthropic-beta: fast-mode-2026-02-01

Install

# Via pi package manager
pi install npm:@linioi/pi-fast-mode

# Or from source
git clone https://github.com/RimuruW/pi-fast-mode.git
cd pi-fast-mode
pi install .

Use

/fast          # toggle on ↔ off
/fast on       # enable fast mode
/fast off      # disable fast mode
/fast status   # show current state and supported APIs

Status Indicator

State Footer Meaning
active ⚡ fast fast mode on, current model/API supports it
unsupported ⚡ n/a fast mode on, current model/API unsupported
off (hidden) fast mode off

How It Works

When fast mode is enabled and the current model is supported, the extension applies the provider-specific fast-path patch:

{ "service_tier": "priority" }

for OpenAI responses APIs, and

{ "speed": "fast" }

plus the anthropic-beta: fast-mode-2026-02-01 request header for Claude Opus 4.6 on anthropic-messages.

This keeps OpenAI support as-is while matching Claude Code's fast-mode shape for Anthropic. The flag is persisted across sessions.
