The latest AI model from Phi, Phi-4, is now available in GitHub Models.

Phi-4 is a 14B parameter state-of-the-art small language model (SLM) that excels at complex reasoning and conventional language processing.

GitHub Models makes it easy for every developer to build AI features and products on GitHub.

Easily try, compare, and implement this model in your code for free in the playground or via the API. Compare it to a previous Phi model using the side-by-side feature in GitHub Models.

The latest AI model from Mistral, Codestral 25.01, is now available in GitHub Models.

Codestral 25.01 is explicitly designed for code generation tasks. It helps developers write and interact with code through a shared instruction and completion API endpoint. As it masters code and can also converse in a variety of languages, it can be used to design advanced AI applications for software developers.

You can now specify a custom JSON schema as a response format, alongside the existing text and recently released general JSON option. When JSON schema is selected, an input box will allow you to define your desired schema format directly in the playground.

This enhancement provides more control if you’re working with models that require structured responses, helping to mitigate issues like models outputting unnecessary tokens. You can either specify a single object or an array of objects. Additionally, you can save this JSON schema as a preset so that you can use it again later.

JSON Schema structured outputs are currently only supported for the GPT 4o model, and specifically for the api-version: “2024-08-01-preview”.

GitHub Models makes it easy for every developer on GitHub to build AI features and products, with access to top AI models via a playground, API, and more.

Today, we’ve added access to OpenAI’s brand new o1 model. The new o1 model replaces o1-preview, and offers even better performance in complex tasks. You can learn more about this launch and its availability on both GitHub Models and Copilot in our blog post.

Start working with o1 directly in our GitHub Models playground. You can even compare it side-by-side with GPT-4o to evaluate how they work differently.

If you’re ready to jump in and integrate o1 into your code, check out our API.

The GitHub Models playground now shows your real-time token usage, including both input and output counts, as well as latency information in its responses. The analytics are accessible via the top bar, helping you more efficiently optimize prompts, evaluate model costs, and monitor response times.

Additionally, clicking on the information in the top bar now opens a modal with more details about the token and latency metrics:

You can now use the new “Improve Prompt” button next to your system prompt in the Models Playground.

A system prompt is a predefined instruction or guideline that sets the behavior and tone for an AI model, helping it respond in a specific way to user inputs. This AI-powered tool will refine and optimize your prompt to help you get the best possible results from your chosen model.

GitHub Models now supports the ability to retrieve structured JSON responses from models, making it easier to integrate AI outputs into applications and workflows.

While this functionality was already available via our API, this update adds it to the UI.

Supported models include OpenAI (except for o1-mini and o1-preview) and Mistral models.
