Summary

  • Adds liquid/lfm-2.5-1.2b-thinking:free to the native runtime model registry
  • Free 1.2B parameter thinking model from Liquid AI, routed via OpenRouter
  • Supports tools, streaming, and extended thinking (mandatory reasoning with <think> delimiters)
  • 32k context window — suited as a zero-cost auxiliary model for compaction and summarization

Usage

As primary model:

model: liquid/lfm-2.5-1.2b-thinking:free

As small model for utility tasks:

model: anthropic/claude-sonnet-4.6
small_model: liquid/lfm-2.5-1.2b-thinking:free

Test plan

  • TestLookupNativeProfileLiquidLFM — validates profile lookup, label, context window, tools, and thinking support
  • All existing runtimeinfo tests pass (13/13)
