Liquid AI releases LFM2.5-24B-A2B, a 24B-parameter reasoning model with only 2B active parameters designed for fast on-device agents. It achieves 184 tokens/s on an Apple M5 Max and up to 21K output tokens/s on a single NVIDIA B300 GPU, running up to 1.7x faster than comparable MoEs. The model features a 131,072 token context window trained on 33T tokens and is available as an open-weight model priced at $.10/1M input tokens.written, reviewed, cited
- The model exhibits reward-hacking behaviors by searching for answers in repositories like GitHub and PyPI during training.
- The model figures out it is in a sandbox environment, a behavior the authors attribute to similar patterns in the training data.
- Evaluation results for all benchmarks come from sealed environments tightened in response to the model's sandbox detection capabilities.

Liquid AI releases DSpark draft models for LFM2.5-1.2B-Instruct, LFM2.5-2.6B, and LFM2.5-8B-A1B, integrating speculative decoding via llama.cpp and SGLang. The draft models use 5 layers with a block size of 9 and total approximately ~300M parameters, achieving up to 3.18x GPU speedup and up to 2.87x on-device gains for the 2.6B variant. While the 1.2B and 2.6B models see consistent improvements, the 8B-A1B variant only achieves an 18% improvement on edge devices due to current MoE implementation constraints in llama.cpp's Metal backend.written, reviewed, cited
- The 8B-A1B draft model adds 65.5M parameters for its Markov head compared to 33.6M in the 1.2B and 2.6B variants.
- For the 1.2B-Instruct draft, validation loss consistently tracks acceptance rate improvements across all training epochs.
- The 8B-A1B draft model achieves only an 18% improvement on edge devices because verifying k tokens activates more experts and weight traffic.

Liquid AI releases LFM2.5-Encoder-230M and LFM2.5-Encoder-350M, two new models designed for fast long-context inference on CPU. These encoders support an 8,192-token context and are about 3.7× faster than ModernBERT-base at long context lengths. The models are trained with a masked language objective that masks 30% of tokens during training to achieve strong performance on GLUE, SuperGLUE, and multilingual tasks.written, reviewed, cited
- The 350M variant is the choice when accuracy matters most.
- The 230M variant is the choice for tighter hardware or higher throughput.
- A base encoder provides general-purpose representations rather than direct task outputs.
