Multi-label classification. One forward pass. Zero completion tokens. We fine-tuned LFM2.5-Encoder-230M and LFM2.5-Encoder-350M to score every label at once: no decoding loop, nothing to parse or repair. First in a new encoder demo series, watch it in action. Check out the cookbook:
Context
Liquid AI's classification example assigns a document to several categories by calculating a separate score for every label in one model pass. It fine-tunes the company's small encoders for this task, avoiding the need to generate and then interpret a written answer. Announcement.
The linked cookbook example explains the decisions needed around those scores: train on labeled documents, select score thresholds using validation data, then evaluate on held-out examples. More than one label can clear its threshold. This turns the general-purpose encoder into a specialized categorization component with directly usable outputs.
- token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
