    • 5:07 - Prompt the on-device model with fm respond

      $ fm respond "Provide a basic regex in Swift to parse an email address"
      # Here is a basic regex to parse an email address in Swift: [...]
      
      $ fm respond "Provide a comprehensive regex in Swift to parse an email address" --model pcc
      # [...] Here's a robust Swift implementation using 'NSRegularExpression' to validate a typical email address:

      	--image Screenshot.png
      # The user is using the Mail app.

      	--image Screenshot.png --model pcc --schema schema.json
      # {"app_names": ["Messages", "Mail", "Calendar"]}
      
      $ fm respond --help
    • 7:55 - Sort files with fm respond and a schema

      fm schema object --name "TriagedFileList" \

Return a list of the latest files (i.e., all files that, you can infer from their name in the list, are the latest versions), and then return separately a list of all draft files (i.e., all files that weren't considered final)." \
          "This is the list of all files:\n\n${files_list}" \

    • 8:54 - Install the Foundation Models Python SDK

      pip install apple_fm_sdk
    • 10:00 - Create a session and respond to a prompt

      import apple_fm_sdk as fm

    • 0:00 - Introduction
    • Overview of the Foundation Models Framework — guided generation, tool calling, and new macOS 27 features like image inputs and server model access.

    • 1:22 - Introducing the fm CLI and Python SDK
    • Two new ways to access Apple Foundation Models on macOS: the fm command line tool (pre-installed with macOS 27 for terminal-based prompting and automation) and the Foundation Models SDK for Python (for ML engineers who work more in Python than Swift).

    • 3:23 - Command line tool
    • How to use the fm command line tool — browsing available commands, starting an interactive conversation with fm chat, switching between the on-device and Private Cloud Compute models, and saving sessions to resume later.

    • 5:02 - fm respond and structured output
    • How to use fm respond for inline scripting — passing prompts and getting responses as terminal output, using the model and image options, and combining fm schema object with the schema option to produce structured JSON outputs.

    • 6:11 - Automating file management with fm
    • A practical automation demo: using fm in a shell script to intelligently sort a messy presentation folder — prompting the model with a file list to classify drafts versus finals, generating structured JSON output, and routing files to backup and archive accordingly.

    • 8:52 - Python SDK
    • Introduction to the Foundation Models SDK for Python — installation requirements (Python 3.10+, Xcode, Apple Silicon), core features mirroring the Swift framework (text and image inputs, streaming, tool calling, guided generation), and its value for ML engineers and rapid prototyping.

    • 9:42 - Prompting, tool calling and guided generation
    • How to use the Python SDK in a grocery app prototype — creating a LanguageModelSession, calling session.respond with a prompt, exposing tools for the model to fetch order history, and using the fm.generable decorator for structured output into a typed ItemsSuggestion object.

    • 10:44 - Building an evaluation pipeline in Python
    • A case study using the Python SDK with Jupyter, Pandas, and matplotlib to evaluate three prompt implementations for a cart completion feature — generating outputs with the on-device model, scoring them with a server judge model on criteria like excess items, missing items, and hallucinations, and visualizing results to guide prompt iteration.

    • 15:20 - Next steps
    • Summary of the new macOS tools and next steps: explore fm in Terminal, visit the Python SDK GitHub for example snippets, and build an evaluation pipeline to measure and improve prompt quality.
