Oxygen AI Positron for Eclipse 8.1

February 10, 2026

Version 8.1 of Oxygen AI Positron Assistant for Eclipse brings the latest AI-powered authoring enhancements to users of Oxygen XML tools within the Eclipse environment. This release includes support for OpenAI GPT-5.2 models, enhanced context awareness, and smarter handling of document attachments further boost productivity.

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.

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, operating system details, current date, and caret or selection data (Oxygen 28.1 or newer). Having richer contextual information leads to higher-quality AI responses.

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 now decide whether a custom AI action sends both content and referenced images to the LLM by using the

"input-type":
            "markup-with-images"

JSON property. This helps you include images only when they are relevant for the AI response. 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.

Oxygen AI Positron for Eclipse 8.0

November 18, 2025

Oxygen AI Positron 8.0 for the Eclipse distribution adds a dedicated AWS Bedrock connector and new AI model options (OpenAI GPT-5.1, Claude Sonnet 4.5, Claude Haiku 4.5, and xAI Grok 4 Fast) allowing you to choose the right balance between quality and speed for your tasks.

Development moves faster with smarter, project-specific prompts and the AI can now make targeted changes with the edit_document tool.

New Dedicated Connector: AWS Bedrock

You can now connect AI Positron to the AWS Bedrock service using a dedicated connector. Get instant access to enterprise-grade AI models with simple API key authentication, real-time streaming responses, and multi-modal capabilities.

Smarter AI Context Prompt Setup

You can now use the Generate agent instructions action to create a project-specific context prompt. This prompt helps the AI understand the structure and conventions of your project, so that AI-generated content matches your project’s specific organization, framework, and metadata requirements. The generated prompt is saved as a Markdown file in your project and is used by AI Positron when you use chat or other AI actions.

Edit Document Tool

When using agentic chat to make changes to topics, small changes (e.g. attribute values, spelling corrections) can now be made more easily by the AI engine using the newly available edit_document tool that performs exact string replacements in a specified file.

Generate Code Improvements (Oxygen 28.0 Required)

The Generate Code development AI action now provides the structure of the associated XML file in the prompt, ensuring better results. For XSLT and XQuery, it includes the structure of the XML document associated in the transformation scenario, while for schemas (XSD, Schematron, DTD, RNG, RNC), it includes the structure of an instance that has the schema associated in a validation scenario.

OpenAI GPT-5.1 Models Available

The flagship GPT-5.1 and GPT-5.1 Thinking models are now available in the list of OpenAI models to choose from.

xAI Grok 4 Fast Models Available

The latest fast models for xAI Grok are available to choose from, including Grok 4 Fast and Grok 4 Fast (Non Reasoning).

Claude Sonnet 4.5 Model Available

The Claude Sonnet 4.5 model (listed as their strongest model for building complex agents) is now available in the list of AI models to choose from.

Claude Haiku 4.5 Model Available

The Claude Haiku 4.5 model (listed as their latest small model) is now available in the list of AI models to choose from.

Improved Tool Names and Descriptions

All the names and descriptions of tools that are available in the chat or AI actions were improved for greater accuracy and relevance. This allows the AI to better decide what tool to call and what parameters to pass, thus improving the agentic AI workflows.

Custom Actions Prioritized

Your custom actions are now displayed before the built-in actions wherever AI actions are shown, so you can access them more quickly.

Oxygen AI Positron 7.0

September 15, 2025

The latest release of the Oxygen AI Positron Assistant for Eclipse users, the Oxygen AI Positron Assistant now supports the latest OpenAI GPT-5 models for improved AI-driven interactions. Additionally, enhanced handling of Word (.docx) attachments further improves the user experience.

Support for OpenAI GPT-5 Models

After configuring the OpenAI connector, you have access to the latest GPT-5 models, including GPT-5 (with default or minimal reasoning), GPT-5-mini, and GPT-5-nano, in the Chat view. This gives you access to improved AI capabilities for chatting or invoking AI actions.

Invoke Tools Defined on Model Context Protocol Servers

The Anthropic Model Context Protocol (MCP) is an open standard that enables developers to build secure, two-way connections between their data sources and AI-powered tools. You can now configure a reference to a MCP configuration file in the AI Positron Assistant's Model Context Protocol preferences page. The AI Positron Enterprise add-on utilizes this file to load extra tools that can be called by the AI engine when using the chat modes or invoking custom AI actions.

Connect External Tools to AI with Model Context Protocol

AI-powered Automatic Fixes for Invalid XML Responses

When an invalid or not well-formed XML document is generated by the AI model, Oxygen AI Positron automatically detects the document type, validates the document, and tries to correct any detected errors, thus ensuring that the generated XML documents are valid.

Fix Validation Problems in the Editor with AI Positron Fix

You can fix validation problems in the editor (Text and Author modes) with the AI Positron Fix action, available in the Quick Fix menu and in the tooltip when you hover over a validation problem. This helps you resolve issues faster without leaving your editing context.

Attach Files to Edited Message Prompts

When editing a message prompt that was sent to the AI, you can use the convenient Attach action to attach images (in PNG or JPEG format) or files (in various formats including plain text, XML, Markdown, Word, Powerpoint, or PDF). This allows you to provide additional context, helping the AI generate more relevant responses.

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

You can now paste a screenshot directly into the chat input area to share visual context with the AI and reduce the need to retype details.

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.

Flexible OAuth2 Configuration via the Positron Custom Connector Add-on

Use the Oxygen AI Positron Custom Connector add-on to connect the Positron Assistant Enterprise plugin to AI services that expose a REST API (for example, OpenAI-compatible endpoints). You can now configure the OAuth2 token endpoint with the POSITRON_CONNECTOR_AUTH_TOKEN_URL environment variable and set the OAuth2 scope with POSITRON_CONNECTOR_AUTH_SCOPE. This lets you use identity providers that require custom token URLs or scopes.

Improved Word (.docx) Attachment Handling

When you attach a Word (.docx) file, the text and images are kept in their original order. This preserves the document’s structure and context, so you get more accurate responses.

Dedicated Connector for xAI Grok

You can now connect the Enterprise distributions of Oxygen AI Positron Assistant to the xAI Grok service using a dedicated connector.

Search In Project Tool

The new search_in_project tool allows the AI to quickly find precise matches across your project files. It supports wildcards (for example, *.dita), regular expressions, and XPath filters, making searches both flexible and powerful. With this feature, the AI can ground its answers in your project content.

Debug Custom AI Action Prompts

For debugging custom AI action prompts, you can see the exact prompt that is sent for any custom AI action (in the Chat view) by setting the oxygen.ai.positron.development.mode system property with the value of true in the parent Oxygen application.

New XSpec Template for Testing AI Actions

Use the new AI Action Test file template to create XSpec tests that validate your AI actions. It includes a commented skeleton that shows where to define inputs and expected results.

Enhanced Generate Code Experience

Easily generate code directly within the editor by pressing Ctrl + G (Command + G on macOS). This shortcut instantly opens a convenient text field at the cursor location, allowing you to describe the code you want to generate without interrupting your workflow.

Flexible AI Validation and Correction Controls

You now have separate controls for automatic validation and correction in AI Positron Preferences. Choose whether the AI attempts to fix validation errors in complete XML documents it returns, well-formedness errors in XML fragments it returns, and validation errors when AI-generated XML is inserted into your document. This lets you control when automatic fixes happen and avoid unwanted changes.
