LFM2.5-2.6B (free)

LFM2.5-2.6B appears as a free-tier entry on OpenRouter's Liquid provider index, sitting alongside LFM2.5-Embedding-350M and LFM2-24B-A2B within the ten Liquid models accessible through the OpenRouter unified API. The 2.6B naming suggests a compact, mid-sized model in Liquid's lineup, distinct from the much larger 24B variant and from the embedding-only 350M sibling, positioning it as a lightweight option for users exploring the family without committing to heavier inference costs.

Because the supplied evidence comes only from gateway and aggregator listings rather than Liquid AI's own model card or technical report, the overview avoids asserting specific architectural details, benchmark numbers, or open-weight status for LFM2.5-2.6B. What can be stated is the practical positioning: it is a free-access Liquid model offered through the OpenRouter gateway, intended for developers who want to experiment with a compact entry from the family before stepping up to larger siblings like LFM2-24B-A2B.
