Oxygen AI Positron 8.1 for Desktop
Oxygen AI Positron 8.1 for Desktop delivers a new level of productivity, security, and flexibility for users leveraging AI in their XML authoring workflows. This release introduces support for OpenAI’s latest GPT-5.2 and GPT-5.2 Thinking models and enables more accurate and context-aware agentic tasks. Sensitive data masking is now built-in, automatically protecting personal information in AI requests, with the ability to extend coverage to custom data types. The review experience is streamlined as AI-modified files are now presented directly in the chat for easy acceptance or rejection of changes. Token consumption for AI prompts and tools has been optimized, reducing costs and improving efficiency.
A new Planner chat mode empowers users to coordinate complex, multi-step, project-wide changes, while smarter handling of PDF and Word attachments enables advanced document processing. The chat interface now provides richer context about your editing environment, leading to higher-quality AI responses. Users gain granular control over AI capabilities with the new Tools selector, and can now create custom chat modes and actions, including those with vision support for image analysis. Additional enhancements include agentic AI Positron Fixes, improved alternate text generation for images, preservation of structure and styles in attached documents, and new tools for command-line operations and resource management.

OpenAI GPT-5.2 Models Available
Sensitive Data Masking for AI Requests
Improved Review Experience for AI-Modified Files
Optimized Token Consumption for AI Prompts and Tools
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.

Oxygen AI Positron 8.0 for Desktop
Oxygen AI Positron 8.0 combines the AI Positron Assistant and AI Positron Assistant Enterprise add-ons into one unified add-on. This single installation simplifies the setup process and makes it easier to get started.
AI assistance for authoring and development is now more effective. Project-aware prompts created using the Generate agent instructions action and support for multiple context files provide better guidance. New tools include project-wide search, directory listing, and precise edit operations. You can also refactor XML directly from the chat in Agent or DITA Agent modes.
You can now create multiple connections to each supported AI service provider, giving you greater flexibility in choosing the right AI assistance for your tasks. The supported connectors list has been enhanced with the addition of a dedicated AWS Bedrock connector. Furthermore, new AI model options include OpenAI GPT-5.1, Claude Sonnet 4.5, Claude Haiku 4.5, and xAI Grok 4 Fast.
This version also introduces an experimental local Model Context Protocol (MCP) server so desktop AI assistants can start the Oxygen application and validate, edit, and refactor documents through Oxygen tools.

Oxygen AI Positron 7.0
The latest release of the Oxygen AI Positron Assistant for desktop tools introduces support for OpenAI's cutting-edge GPT-5 models, enhancing AI capabilities for chat and AI actions. The release includes the ability to invoke tools defined on Model Context Protocol Servers, ensuring seamless integration with external AI-powered tools. AI-powered automatic fixes now ensure XML documents remain valid when an invalid or not well-formed document is generated by the AI model. Additionally, you can now manage attachments using visual chips, paste screenshots directly into the chat for better context, and edit attached resources from prompts that have already been sent to the AI. The introduction of multiple chat modes, the new search_in_project tool, and improved handling of Word (.docx) attachments further enrich the user experience.

Manage Attachments with Visual Chips
You can now see your attached files as chips in the chat input
area, making it easy to review and remove individual attachments. If you want more
control, you can optionally use @ to reference specific files in your
instructions. Unreferenced attachments are still included automatically at the end of
your message.
Attachments are also displayed as chips in the chat, so you can quickly identify and access files sent to the AI.
Additionally, when you select content in the editor, a chip named
selection appears in the AI Positron chat input area. It represents
your current selection and updates whenever you change it. You can reference it by
typing @selection.
Paste Screenshots into Chat
Multiple Chat Modes
You can now choose between three chat modes in the Chat view:
- Agent - Discuss your project, set goals, or give instructions. The AI proposes changes and you are required to review and approve them.
- DITA Agent - Specially tuned for DITA-specific projects, provide goals or instructions and let the AI explore your project and apply project-wide changes with your approval.
- Ask - Get answers and explanations from the AI. This read-only mode uses search tools when needed and does not change your files.
All modes automatically use your current context (project location, current document and type, and the DITA map in scope), so you don’t need to include this information in your prompts.
