LFM2.5 2.6B

LFM2.5-2.6B is a text-generation model from LiquidAI with 2.69B parameters, a 131,072-token context window, and a 128,000-token vocabulary. It uses a hybrid architecture with 30 layers, including 22 double-gated short convolution blocks and 8 GQA layers, and was trained on 34 trillion tokens. The model is described as general-purpose, text-only, and post-trained for agentic workloads, with multilingual coverage across 16 languages. It is distributed under the lfm1.0 license and supports safetensors and text-generation tags.

Freshness 74 out of 100. Repository age: 79 days old, Jul 28, 2026. Measures age, not quality.
Popularity 70 out of 100. 114,916 downloads in 30 days; 831 lifetime likes. Checked Oct 15, 2026. Measures adoption, not quality.
What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))

Best for

  • Local text generation with a compact model footprint
  • Tool-use and multi-step agentic task experimentation
  • Instruction-following and conversational workflows
  • Multilingual text generation across the listed languages
  • Fine-tuning or inference with compatible local runtimes

Tradeoffs

  • Source provides limited detail beyond the model card summary.
  • No independent performance or compatibility validation is included.
  • Usefulness depends on local setup and supported runtimes.
  • Agentic behavior may require careful prompting and oversight.
  • Not positioned as a replacement for larger or more specialized models.
