🚀 LibreChat v0.8.1

The v0.8.1 release of LibreChat

🏞️ Highlights

Major features and improvements since v0.8.0

🤖 Agent Handoffs (Beta)

Agents can now be configured to transfer control of conversations to other specialist agents when specific expertise is needed.

📎 Upload to Provider Support

Files can now be directly uploaded to and handled by supported providers, removing the need for intermediate OCR and other multimodal processing steps.

🖼️ Improved Artifact Management and Shareability

Artifacts have been improved with version control capabilities, better UI interactions and rendering support, and can now be viewed within shared conversations.

🤖 Model Updates

Gemini 3 support with pricing
GPT-5.1 support with codex variants
Grok 4 variants (fast, 4-1-fast, code-fast) with context rates
Claude Opus 4.5 & Haiku 4.5 with token rates and window limits
Zhipu AI GLM family support with comprehensive context windows and pricing
Enhanced model pricing coverage for DeepSeek R1/V3, Qwen family, Amazon Nova Premier, Llama 3.3, gpt-5-pro and others with improved pattern matching

⚙️ Other Notable Changes

Langfuse Tracing support
Helicone AI Gateway integration
Bedrock Prompt Caching support
Screens are now prevented from sleeping during response generation
File names can now be used as context for Anthropic document uploads
Distributed Leader Election with Redis for multi-server-instance coordination within cluster deployments
Whether specific tool badges (file search, mcp servers, etc.) will be rendered in the chat input can now be configured via Model Specs
Accessibility improvements across the entire app for better keyboard navigation, screen reader support, and accessibility standards compliance
Helm Chart enhancements: custom deployment labels, annotations, init containers, ConfigMaps support, and additional RAG API environment variables
MCP Registry System restructure with distributed caching, leader-follower coordination, timeout-protected server initialization, and user-scoped tool caching
