Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@tifan/pi-fast-mode

Toggle OpenAI Fast Mode per model and track response TPS.

Install

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

Usage

Run /fast to open the list of supported models. Select a model to toggle Fast Mode. Enabled models are marked ✓. The setting is saved per exact provider/model pair.

Run /tps to toggle response TPS. The setting is saved in the same configuration file.

When TPS is enabled, the status shows the latest response rate, median response rate, and median time to first token:

last 58 t/s · med 44 t/s | 2.1s ttft

Response TPS uses Pi's provider-reported output tokens divided by the time from turn start to assistant message end. It includes reasoning tokens and response wait time. It does not include time spent executing tools.

Fast Mode adds service_tier: "priority" for these exact models:

openai/gpt-5.4             openai-codex/gpt-5.4
openai/gpt-5.5             openai-codex/gpt-5.5
openai/gpt-5.6             openai-codex/gpt-5.6
openai/gpt-5.6-sol         openai-codex/gpt-5.6-sol
openai/gpt-5.6-terra       openai-codex/gpt-5.6-terra
openai/gpt-5.6-luna        openai-codex/gpt-5.6-luna

Configuration

Preferences are stored at $PI_CODING_AGENT_DIR/extensions/pi-fast-mode.json:

{
  "models": ["openai-codex/gpt-5.6-luna"],
  "tpsEnabled": true
}

tpsEnabled defaults to true when it is missing. Unsupported models cannot be enabled.
