1. Kronos: Open-Source Foundation Model for Financial K-Line Markets

Kronos is a decoder-only foundation model pretrained on financial K-line data from more than 45 global exchanges, with a two-stage tokenizer designed for noisy OHLCV sequences. Its AAAI 2026 acceptance and released fine-tuning scripts lower the barrier to building reusable forecasting and signal-research models for financial time series. Source-github

2. MemT-1.0 Introduces Memory-Native Architecture for Foundation Models

MemT-1.0 treats memory as part of model computation rather than an external retrieval add-on, using Gated DeltaNet-2 with stable token-level memory updates and a Mixture-of-Storage approach. This points toward foundation models that can accumulate and reuse information natively, a key requirement for continual learning and long-horizon agents. Source-huggingface

3. Holi-World Builds Holistic World Intelligence from Human Egocentric Experience

HOLI-WORLD converts human egocentric recordings into scalable world representations that connect scene structure, object semantics, and interaction histories across viewpoints and time. The work could reduce manual annotation for embodied AI and provide a data engine for holistic world models trained on everyday human experience. Source-huggingface
