RubyLLM 1.15: Image Editing + Cost Tracking + Less Glue Code 🖼️💸🛠️

RubyLLM 1.15 removes glue code around images, costs, tools, callbacks, and Rails persistence.

If Ruby can infer a tool signature, RubyLLM now infers it. If a provider reports usage, RubyLLM can turn it into cost. If Rails already has a blob, RubyLLM reuses it instead of downloading and uploading it again.

🖼️ Image Editing

Same method, same attachment shape: paint now paints from scratch or edits an existing image.

RubyLLM.paint can edit existing images with OpenAI's GPT Image models. Pass one or more source images with with:, add a mask: when you want to constrain the editable area, and use params: for provider-specific image options.

image = RubyLLM.paint(
  "Turn the logo green and keep the background transparent",
  model: "gpt-image-1",
  with: "logo.png"
)

with: accepts the same attachment sources RubyLLM supports elsewhere: local files, URLs, IO-like objects, and Active Storage attachments. Multiple source images work too:

image = RubyLLM.paint(
  "Combine these references into a postcard illustration",
  model: "gpt-image-1",
  with: ["person.png", "style-reference.png"]
)

Image responses now expose provider usage data, and GPT Image pricing is represented in the model registry so image input/output costs can be calculated with the same API shape used by chats and messages:

image.tokens.input
image.tokens.output
image.cost.input
image.cost.output
image.cost.total

Fixes #138 and #512.

💸 Conversation Costs + Normalized Tokens

Token counts answer "how many?" Cost helpers answer the next question: "how much?"

RubyLLM now has first-class cost helpers for token-priced conversation usage:
