Assistants Client (Beta)

Description

An Assistant is a configured AI entity with a model, instructions, and optional tools. It operates on ThreadsClient (conversations) by creating Runs that execute the assistant's logic.

Details

Client for the OpenAI Assistants API v2 (Beta). Assistants are AI agents that can use tools (code interpreter, file search, custom functions) and maintain persistent state. Access via client$assistants.

Typical workflow

  1. Create an assistant: client$assistants$create(model, instructions, tools)

  2. Create a thread: client$threads$create()

  3. Add a user message: client$threads$messages$create(thread_id, "user", "...")

  4. Create a run: client$threads$runs$create(thread_id, assistant_id)

  5. Poll the run until status is "completed"

  6. Read the assistant's reply: client$threads$messages$list(thread_id)

width

Numeric. Width of the saved PNG in inches. Default: 7.

height

Numeric. Height of the saved PNG in inches. Default: 5.

dpi

Integer. Resolution in dots per inch. Higher DPI gives sharper images (important for text readability) but larger file size. Default: 150. Use ⁠200+⁠ when text in plots must be legible.

Arguments

url

Character. A publicly accessible image URL. Supported formats: JPEG, PNG, GIF (static), WebP. Example: "https://example.com/chart.png"

detail

Character. Controls how the model perceives the image, trading off between cost/speed and accuracy:

  • "auto" (default) — model chooses based on image size

  • "low" — 85 tokens flat; fast and cheap; good for simple images, icons, or when spatial detail is unimportant

  • "high" — tiles the image at 512px squares (up to 1105 extra tokens); use for charts with small text, detailed figures, or when precise spatial understanding is needed

Value

A named list (content part) to be placed inside a message's content list. Use with create_multimodal_message or construct messages manually.

Helper Functions for Multimodal Content

Description

Most modern LLMs (GPT-4o, Claude 3, Gemini, Qwen-VL, etc.) support multimodal input — you can send both text and images in the same message. Images are embedded inside the content field of a "user" message as a list of content parts.

There are three ways to provide an image:

  1. Image URL — the model downloads it directly (image_from_url)

  2. Local file — read and Base64-encoded automatically (image_from_file)

  3. R plot — save a ggplot2 / base R figure and send it (image_from_plot)

Use create_multimodal_message to combine text + multiple images into a single ready-to-use message object.

Details

Functions to construct image content objects for sending images to vision-capable LLMs via the Chat Completions API.
