TL;DR:
In November, SmythOS brought enterprise-grade observability to the SDK with OpenTelemetry support, letting you track every agent action with traces, metrics, and detailed logs. The platform got smoother across the board: clipboard attachments make file sharing instant, expandable editors give you breathing room for complex logic, and the default Claude model upgraded to the more stable Haiku 4.5. Debugging became sharper with visual highlights for active components and automatic disabling of inactive ones. Weaver now runs in the background, the test sidebar got a responsive redesign with voice embodiment built in, and a modern sans-serif font refresh gives the entire interface a cleaner look. These updates make SmythOS more observable, more productive, and more polished every day.
Everything listed below is already live across all SmythOS accounts.
New Features
OpenTelemetry support in the SmythOS SDK
Initialize telemetry at the start of your application and automatically record every action performed by your agents. Traces, metrics, and detailed logs of agent behavior get captured and exported for analysis. Initialize it once, and all your agent actions are recorded. This is a significant step forward for monitoring and debugging production agents.
Clipboard-based attachment support for chat and chatbot
Paste images and files directly from your clipboard without extra clicks. Just copy and paste. File uploads are streamlined, intuitive, and work seamlessly across both chat and chatbot environments.
Expandable text and code editors
Whether you’re writing complex logic or debugging code, you can now expand your editor to get a better view. A small feature with big productivity benefits.
Builder and Debugging
Smarter debugging flow
Inactive components are now disabled during debug sessions, while active components get highlighted with step icons. This makes it easier to focus on what’s running and understand where you are in the execution flow.
Redesigned test sidebar
The test sidebar now features responsive embodiment tabs and an overflow menu, keeping everything organized and scalable as you switch between testing modes.
Voice embodiment in test sidebar
Voice testing is now integrated directly in the test sidebar. No more context switching between tabs to test voice interactions.
LLM model selection dropdown in chat
Switch between different AI models directly from the chat interface. Compare outputs, test different capabilities, or optimize for cost versus performance in real time.
Model and Runtime Updates
Default Claude model updated to Haiku 4.5
The deprecated Claude 3.7 model has been replaced with Claude Haiku 4.5, giving you access to a more stable and supported model with better performance right out of the box.
Run Weaver in the background
Weaver can now operate while you multitask. Start a build or modification and switch to other work without waiting.
Interface and Experience Polish
Modern sans-serif font across the application
The entire interface now uses a clean, modern sans-serif typeface, giving SmythOS a fresh and professional look.
Clearer error messaging
When you stop content generation, you’ll see “generation interrupted by user” instead of technical jargon. Clear language matters when troubleshooting.
Navigation links open in new tabs
Links no longer risk losing unsaved work. They open in new tabs by default, keeping your current work intact.
Collapsed sidebar navigation improvements
The collapsed sidebar now shows a clearer visual highlight for the active page, making navigation easier when space is limited.
Collapsible advanced settings in custom model modal
The custom model modal now features a collapsible advanced settings section, keeping primary fields visible while tucking away advanced options.
Bug Fixes
API call component JSON extraction fixed. A critical bug preventing the API call component from extracting data from JSON responses with special character keys like @context and @type has been resolved. If you work with JSON-LD formatted data or vendor-specific APIs, this fix opens up new possibilities.
Where to Start
- Initialize OpenTelemetry in an SDK project to see traces and metrics flowing into your monitoring stack.
- Run a debug session to experience the new visual highlights for active and inactive components.
- Use the LLM dropdown in chat to compare different models side by side.
- Copy an image and paste it directly into chat to test clipboard attachment support.
- Expand a code editor while writing complex logic to enjoy the extra screen space.
- Check the updated interface for the new font and cleaner navigation highlights.
These November updates strengthen the foundation for observable, productive, and polished AI agent development heading into the next release cycle.
