Oxygen AI Positron for Content Fusion
OpenAI GPT-5.2 Models Available
The flagship GPT-5.2 and GPT-5.2 Thinking models are now available in the list
of OpenAI models to choose from.
Optimized Token Consumption for AI Prompts and Tools
The prompts and tools that the AI uses to generate answers have been improved
to consume fewer tokens/credits.
New Planner Chat Mode for Resource Consuming Tasks
The newly-introduced Planner chat mode is available for complex, token-intensive operations (e.g. “Translate all files in the current folder” or “Find all conrefs and replace them with conkeyrefs in userguide.ditamap”).
After being given the prompt, the AI explores your project, proposes a multi-step plan, and, after your approval, delegates each step to the most suitable AI agent. This means large, project-wide changes can be coordinated without hitting LLM context limits, while still showing you the tool calls and results for review.
More Context Information Available in Chat
The AI chat now automatically includes additional information about your
environment and editing context, such as the Oxygen application version, current date, and
caret or selection data (Content Fusion 9.0 or newer). Having richer contextual
information leads to higher-quality AI responses.
Documentation and APIs to Create New Chat Modes
You can now officially define new chat modes by creating new AI actions that
contain the
"output-action": "agentic" property.
For more details, see Creating Custom Chat ModesTools to List and Invoke AI Agents
Newly added tools make it possible to create powerful new chat modes to plan
complex changes and then use separate agents for each part of the plan. For more details,
see AI Positron User Guide: Tools to Invoke AI Actions or Agents.
List Directory Tool (Available with the Upcoming Content Fusion 9.1)
When using an agent chat mode, a new list_dir tool is
available to list the contents of a directory, which helps the AI understand the structure
of your project.
Control AI Action Visibility
You can now choose whether a defined AI action is visible in the UI or only
available to other AI actions as a sub-agent by using the new visibility
property. For more details, see AI Positron User Guide: Visibility Property.
Create AI Actions with Vision Support
You can control whether a custom-defined AI action sends both content and
referenced images to the LLM by using the
"input-type":
"markup-with-images" JSON property.
For more details, see markup-with-images.
Generate Image Alternate Text Improvements
The Generate Image Alternate Text action can now be used on
all images that are referenced within a document at once, while you can still use the
action on individual selections as well.
Preserve Structure and Styles for Attached Word and PDF Documents
When attaching Word (.docx) or PDF documents in the chat, their internal
structure (headings, lists, tables, code blocks) and styling (bold, italic) are now
preserved when being sent to the AI so that it better understands the context of the
document.
