Allison summarizes the launch of OpenAI’s GPT-5 models on GitHub Models, highlighting new features, model variants, and pathways for developers to leverage advanced AI in coding workflows.

GPT-5 is now generally available in GitHub Models

OpenAI’s GPT-5—their most advanced AI model to date—is now accessible to developers and organizations via GitHub Models. GPT-5 delivers significant improvements over previous versions, particularly in reasoning, code quality, and multimodal conversation capabilities.

Key Features

Advanced Reasoning: Enhanced ability to perform complex, multi-step tasks with clearer logical structure.
Improved Code Quality: Better at generating, refining, and explaining code with minimum prompting.
Agentic Capabilities: Designed to act as an intelligent coding collaborator and assistant.

GPT-5 Model Variants

gpt-5: Optimized for logic and multi-step operations.
gpt-5-mini: Lightweight, cost-efficient model.
gpt-5-nano: High-speed, low-latency version for performance-sensitive applications.
gpt-5-chat: Advanced for conversational, multimodal, and context-aware tasks, ideal for enterprise use.

How to Access

Models Tab: Enable and select GPT-5 models from the GitHub Models tab.
Playground: Experiment interactively on the GitHub Models playground.
API Access: Utilize the latest models via the GitHub API for custom integration.

Developer Opportunities
