oc-crofai

An OpenCode plugin that adds CrofAI as a first-class provider.

CrofAI provides cheap access to open-weight LLMs. This plugin dynamically discovers available models from CrofAI's API, so you always see the latest models without updating the plugin.

Installation

opencode plugin add oc-crofai

Usage

1. Get an API key from crof.ai
2. OpenCode will prompt you to enter your CrofAI API key when you first use the provider
3. Select "CrofAI" as your provider and choose a model

Alternatively, set the CROFAI_API_KEY environment variable:

export CROFAI_API_KEY="your-api-key-here"

How It Works

The plugin uses three OpenCode hooks:

• config — Registers CrofAI as a provider with @ai-sdk/openai-compatible SDK integration
• provider — Fetches https://crof.ai/v1/models on startup and maps the response (context length, pricing, reasoning capabilities) to OpenCode's model schema
• auth — Provides interactive API key entry with automatic CROFAI_API_KEY env var fallback

Models are fetched once when the provider loads. If CrofAI adds new models, simply restart OpenCode.

Thinking / Reasoning Support

All reasoning-capable models include four variants for controlling thinking depth:

| Variant | Reasoning Effort | Effect | |---------|-----------------|--------| | none | "none" | Disables reasoning — reduces latency and cost | | low | "low" | Minimal thinking, faster responses | | medium | "medium" | Balanced (default) | | high | "high" | Maximum thinking, best reasoning |

Set the variant in your OpenCode agent config:

agent:
  build:
    model: crofai/kimi-k2.6
    variant: high
