Version 4.1.0 - Programmatic API, Agent Overhaul & Observability

Version 4.1.0 is a major feature release introducing a programmatic API with official SDKs, a redesigned agent chat experience, new image generation and presentation capabilities, capability objects, and a full observability stack for self-hosted deployments.

Programmatic API & SDKs

Davinci models can now be created and manipulated programmatically without the UI.

JavaScript SDK: Official TypeScript SDK with session management, webhook support, and full type definitions
Python SDK: Official Python SDK with async support, error handling, and webhook integration
Enables scripting, automation, and integration with external tools and CI/CD pipelines

Agent Chat Redesign

The agent chat experience has been substantially improved.

Session Summary Panel: Live summary showing agent progress, tool usage, and current plan status
Thinking Visualization: See the agent’s reasoning process with collapsible thinking sections
Progress Tracking: Long-running agent operations now show real-time progress updates
Improved Message Handling: Better message ordering with recovery for interrupted sessions
Richer Responses: Improved markdown rendering for agent messages

Capability Objects

A new object type for modeling system capabilities.

New capability object with dedicated icon, properties, and help documentation
The agent can build capabilities, connect them to subjects, and trace relationships between them
Capabilities render in tree views with derived relationship support

Agent Image Generation

The agent can now generate and manipulate images directly within your model.

Generate CAD-style visualizations, concept of operations graphics, and technical diagrams
Auto-generate themed slide backgrounds for presentations
Convert raster images to structured SVG representations
Modify and replace image backgrounds

Presentation Improvements

The agent’s ability to build and edit presentations has been significantly expanded.

Add, delete, move, and replace individual slides
Edit individual slide elements and text blocks
Generate and apply layout templates with automatic space allocation
Better violation detection and automatic correction during slide generation

Task Management

Create individual tasks or full task lists through the agent
Improved task tree generation with better dependency handling
Added decade scale to the Gantt timeline

Agent Version Control

The agent can now interact with the version control system directly — comparing branches and commits, reviewing history for individual objects, and checking uncommitted changes.

SysML v1.x Import (Preview)

Initial support for importing SysML v1.x XMI files from MagicDraw/Cameo, including activity diagrams, interaction diagrams, state machines, and relationships.

Observability Stack

Self-hosted deployments now include a full monitoring stack.

Grafana Dashboards: Pre-built dashboards for LLM usage, system health, tool usage, and user metrics
Prometheus Metrics: Metric collection across all services
Loki Logging: Centralized log aggregation with support for local, AWS, and GCS storage

UI Improvements
