Amplifier OpenAI Provider Module

GPT model integration for Amplifier via OpenAI's Responses API.

Prerequisites

• Python 3.11+
• UV - Fast Python package manager

Installing UV

# macOS/Linux/WSL
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Purpose

Provides access to OpenAI's GPT-5 and GPT-4 models as an LLM provider for Amplifier using the Responses API for enhanced capabilities.

Contract

Module Type: Provider Mount Point: providers Entry Point: amplifier_module_provider_openai:mount

Supported Models

• gpt-5-codex - GPT-5 optimized for code (default)
• gpt-5 - Latest GPT-5 model
• gpt-5-mini - Smaller, faster GPT-5
• gpt-5-codex - Code-optimized GPT-5
• gpt-5-nano - Smallest GPT-5 variant

Configuration

[[providers]]
module = "provider-openai"
name = "openai"
config = {
    default_model = "gpt-5-codex",
    max_tokens = 4096,
    temperature = 0.7,
    reasoning = "low",
    enable_state = false
}

Environment Variables

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

Usage

# In amplifier configuration
[provider]
name = "openai"
model = "gpt-5-codex"

Features

Responses API Capabilities

• Reasoning Control - Adjust reasoning effort (minimal, low, medium, high)
• Stateful Conversations - Optional conversation persistence
• Native Tools - Built-in web search, image generation, code interpreter
• Structured Output - JSON schema-based output formatting
• Function Calling - Custom tool use support
• Token Counting - Usage tracking and management

Tool Calling

The provider detects OpenAI Responses API function_call / tool_call blocks automatically, decodes JSON arguments, and returns standard ToolCall objects to Amplifier. No extra configuration is required—tools declared in your config or profiles execute as soon as the model requests them.

Dependencies

• amplifier-core>=1.0.0
• openai>=1.0.0
