Platform Performance, Billing, Metrics, and AWS Bedrock Integration
New Features:
- AWS Bedrock Integration: Enabled native AWS Bedrock as LLM provider for agents.
- Helicone Integration: Added support for Helicone as AI Gateway for LLM providers.
Improvements:
- Performance Enhancements:
- Reduced streaming latency and improved robustness of agent event pipelines by pre-starting SDK and worker streams and coordinating their outputs.
- Optimized Kubernetes metrics collection.
- Streamlined execution history updates and improved event-loop responsiveness.
- Configuration and Memory:
- Aligned default user memory settings and improved configuration for agent memory behavior.
Bug Fixes:
- UI and Configuration Consistency:
- Corrected default user memory behavior to default-off.
- Robustness and Error Handling:
- Improved error handling and graceful shutdown in streaming event pipelines.
- Ensured that missing or invalid API keys do not break core agent flows, but only disable related features.
Generalist Agent Revamp, UI/UX Enhancements, other fixes and improvements
New Features:
- Generalist Agent Revamp: Major overhaul of the generalist agent experience, including explicit reasoning tools (think/analyze), task grouping in the WebUI, and a well-known agent card endpoint for client discovery.
- Timezone Awareness: Chat sessions now capture and sync the user’s IANA timezone from the browser to the backend.
- User Details Propagation: Webhook and agent invocation pipelines now accept and propagate user identity details.
Improvements:
- UI/UX Enhancements:
- Overhauled the Chainlit WebUI with stabilized task sync indicators, improved task grouping, and live reasoning display.
- Refined logs (monitoring) panel with duration indicators, operation icons, and improved readability.
- Improved file extraction and rendering for images and attachments in chat threads.
- Enhanced connector management in Workbench, including connection switching, multi-delete, and version upgrades.
Bug Fixes:
- Task Grouping and State Persistence: Fixed issues with duplicated chat steps, improper task state persistence, and UI artifacts during session reconstruction.
- Silent Agent Task Creation: Ensured agent task creation is silent in the UI, with accurate progress and completion indicators.
- Connector and Avatar UI: Resolved connector collapsible section bugs, avatar sizing inconsistencies, and improved tool selection logic.
- Logs Panel and Activity Thread: Fixed collapse/expand behavior, duration calculations, and error propagation in activity threads.
Async Platform Stabilization, Agent Improvements, and Model Catalog Expansion
Today’s update is relatively short due to the last update being 4 days ago. We’re now moving to a weekly update every Sunday.
New Features:
- OpenAI GPT-5.1 Model Support: Added GPT-5.1 and additional GPT-5 family variants to the model catalog, with updated context and output token limits for each model.
- Agent Description Field: Introduced editable agent descriptions in the Workbench and auto-generation of agent descriptions. This will be populated in the Agents list in platform.xpander.ai and chat.xpander.ai (or chat.your-company.com)
- Improved robustness of Task scheduler: Migrated platform services to async Redis clients and offloaded non-critical work to background tasks for improved throughput and reliability.
Improvements:
- Environment Management: Added option to configure default environment for agent deployments.
- Agent Activity Logs UI: Refined agent activity logs to group user turns, tool calls, and assistant answers for improved readability.
- UI/UX Enhancements: Improved chat background color handling, loader states for iframe chat initialization, and clarified terminology (e.g., “Executions” to “Tasks”).
- Connector and API Key Management: Added SQL functions for environment filtering, improved API key selection in OAuth2 flows, and refined connector versioning logic.
Bug Fixes:
- UI Consistency: Resolved various UI bugs, including modal race conditions, built-in tool toggling, metrics tab rendering, and chat view background color.
- OAuth2 CLI Flow: Improved OAuth2 CLI login flow with API key selection, authorization UI, and safe redirect handling.
Platform, Agent, and UI Enhancements
New Features:
- OAuth 2.1 Authorization Server: Introduced a full OAuth 2.1 server with Remote OAuth and Dynamic Client Registration for MCP and API endpoints, including JWT-based authentication and discovery endpoints. Check out the API reference here: https://docs.xpander.ai/api-reference
- Workbench: Built-in Tools: Added toggles to enable/disable built-in tools like email sending and sleep toold in the Workbench Tools tab.
- Guardrails and Agno Settings: Expanded agent guardrails configuration, including PII detection, prompt injection detection, and OpenAI moderation categories.
- Agent Version Naming: Added support for naming agent versions, with editable version names displayed throughout the UI.
Improvements:
- Agent Activity Token Metrics: Exposed input and output LLM token breakdowns in agent activity threads and sessions for improved monitoring and billing.
- Connector Versioning and Upgrade Flow: Improved connectors table with version selectors, upgrade confirmation dialogs, and better version management.
- UI/UX Enhancements: Refined metrics counting, improved modal and tab behaviors, clarified terminology (e.g., “Executions” to “Tasks”), and enhanced error handling and session management.
Bug Fixes:
- Tool-Call Reporting and Error Flow: Improved reliability of tool-call lifecycle reporting, error event emission, and UI rendering for tool-call steps.
- Thread Activity Metrics: Corrected token metrics display and layout in thread activity views, ensuring accurate input/output token counts.
- UI Consistency: Resolved various UI bugs, including modal race conditions, built-in tool toggling, metrics tab rendering.
- Connector and Agent Settings: Fixed issues with connector version selection, upload modal behavior, and agent settings persistence.
