- 109M
- 4B
- 2.6%
The cross-encoder fine-tuned with ListNet achieves better performance on NDCG@3 and Spearman correlation, despite having significantly fewer parameters. This has implications for efficient reranking in medical procedure retrieval.
Needle2: 14MB agentic LLM for devices
- 14MB
- 45m
- 2bit
Needle2 achieves competitive performance with larger models while being significantly smaller and more efficient, making it suitable for deployment on phones, wearables, and smart home devices.
Matryoshka training framework for language models
- 500M
- 1.5B
- 3B
The Matryoshka framework trains a suite of language models of increasing size in a nested architecture, reducing total parameter count and enabling efficient distillation and speculative decoding.
Muse Glimmer: local, agentic, multimodal model
Muse Glimmer is an open-source model that operates locally and supports multimodal interactions, offering a unique approach to AI applications.
