1.9.0Feature

Claude Sonnet 4.6, Slack Streaming, and Gateway v1.9.0

Claude Sonnet 4.6 model support, 1M context window beta, native Slack text streaming, Discord Components v2, and nested subagents.

Claude Sonnet 4.6

Anthropic's newest model is now available in Molty. Select Claude Sonnet 4.6 from the model picker in your gateway settings or per-agent configuration.

  • Available immediately in the dashboard model selector
  • Works with all channels (WhatsApp, Telegram, Discord, Slack, Signal, and more)
  • Compatible with existing tool configurations

1M Context Window (Beta)

Anthropic's extended context window is available as an opt-in beta:

  • Up to 1 million tokens of context for supported models
  • Useful for processing long documents, codebases, or extended conversations
  • Enable via the model configuration in your gateway settings

Slack Streaming

Slack channels now support native text streaming - responses appear word-by-word in real time instead of arriving as a single block after the model finishes generating.

Discord Components v2

Discord channels now use the Components v2 API for richer message formatting and interactive elements.

Nested Subagents

Agents can now spawn nested subagents - child agents that inherit the parent's context and tools. This enables more complex multi-step workflows where an agent delegates subtasks to specialized sub-agents.

Security Fixes

This release includes security patches from upstream OpenClaw v2026.2.17. All gateways are recommended to update.
