1. Introduction
GRM-2.6-Air-Opus is a fine-tune of LiquidAI/LFM2.5-1.2B-Thinking, trained on Claude Opus-style reasoning traces to sharpen its reasoning and boost performance on harder problems.
GRM-2.6-Air-Opus is a compact, edge-friendly model built for users who want a taste of Opus-style structured reasoning without the footprint of larger GRM models. It's the "Air" entry in the GRM-2.6 family: smaller and faster, aimed at lightweight local and on-device use.
2. Key Capabilities
- Opus-Style Reasoning, Compact Size: Distilled from Claude Opus-style traces to produce clearer, more organized reasoning at just 1.2B parameters.
- Edge-Ready: Built on LFM2.5-1.2B-Thinking, making it well suited for low-resource and on-device deployment.
- Improved Problem-Solving: Targeted training on harder reasoning traces lifts performance on difficult tasks relative to the base model.
[!Important] 2026-07-27 Update — Chat template.
We updated the chat template for this model to match that of LFM2.5-1.2b-Thinking; if you are using the old version, please update it if you want tool-call compatibility.
3. Performance
GRM-2.6-Air-Opus focuses on practical, lightweight reasoning: getting as much structured thinking as possible out of a 1.2B model.
