better-custom

A better way to add custom providers for Pi and Oh My Pi (OMP).

Features

• Add, edit, or delete custom providers from an interactive wizard
• Supports:
  • OpenAI-compatible endpoints
  • Anthropic-compatible endpoints
  • Ollama-compatible endpoints
• Uses the running host's agent directory automatically
  • Pi: models.json
  • OMP: models.yml / models.yaml
• API key modes:
  • API key (stored verbatim in the active models config)
  • none (writes a placeholder so the provider still loads)
  • existing $ENV and !command keys are still resolved when re-probing
• Auto-probe /models for OpenAI-compatible endpoints
• Multi-select model picker for probed models
• Unique provider names — the wizard refuses to overwrite an existing provider
• Image input enabled by default (input: ["text", "image"]) so vision-capable models receive images instead of having them silently dropped
• Reasoning enabled by default at the xhigh ceiling for newly added models
• Safe delete flow for whole providers or individual models

Install

From npm:

pi install npm:better-custom

From GitHub:

pi install https://github.com/ratatulieoi/better-custom

Usage

After installing, reload pi if needed, then run:

/better-custom

The wizard can:

1. Add a provider
2. Edit a provider
3. Delete a provider

Add a provider

Guides you through:

• provider style (OpenAI / Anthropic / Ollama)
• endpoint
• provider name (must be unique)
• API key method (API key or none)
• model discovery (auto-probe /models) or manual model entry

Newly added models default to input: ["text", "image"] and reasoning: true at the xhigh ceiling. Tune any of this later via Edit provider.

Edit a provider

Pick a provider, then choose:

• Re-probe for new models — query /models again and add ones not yet configured
• Set context window (all models) — apply one contextWindow to every model
• Edit per model — pick a model and edit a single field:
  • Reasoning ceiling (off → xhigh)
  • Vision (text+image vs text-only)
  • Context window
  • Max output tokens
  • Headers / endpoint override (per-model baseUrl and JSON headers)
  • Delete this model
• Add models manually
• Rename provider — change the provider name (key) in the active models config

Per-model edits change one field in place, so untouched fields (cost, headers, overrides) are preserved.

Delete a provider

Lists configured providers and removes the selected one after confirmation.

How reasoning maps to pi

pi exposes six thinking levels: off, minimal, low, medium, high, xhigh. When a model has reasoning: true, pi treats minimal through high as available. xhigh is opt-in and only unlocked when explicitly mapped, and any level set to null is removed. The wizard writes a thinkingLevelMap to unlock xhigh or to cap reasoning below high.

Configuration

The extension uses the host-provided agent directory instead of hard-coding ~/.pi/agent. Existing models.yml, models.yaml, or models.json files are kept in their current format. A fresh OMP config is created as models.yml; normal Pi continues to use models.json.

Saving YAML rewrites its formatting and does not preserve comments.

Files

• index.ts — extension entry point
• package.json — pi package manifest
