[Anthropic Open Source] Agentic Context Engineering (ACE): Self-Improving LLMs via Evolving Contexts, Not Fine-Tuning. A team of researchers from Stanford University, SambaNova Systems and UC Berkeley introduce ACE framework that improves LLM performance by editing and growing the input context instead of updating model weights. Context is treated as a living “playbook” maintained by three roles—Generator, Reflector, Curator—with small delta items merged incrementally to avoid brevity bias and context collapse. Reported gains: +10.6% on AppWorld agent tasks, +8.6% on finance reasoning, and ~86.9% average latency reduction vs strong context-adaptation baselines.
Meet OpenTSLM: a novel family of Time-Series Language Models (TSLMs). This breakthrough addresses a critical limitation in current LLMs by enabling them to interpret and reason over complex, continuous medical time-series data, such as ECGs, EEGs, and wearable sensor streams, a feat where even frontier models like GPT-4o have struggled. The evaluation found that the model provided a correct or partially correct ECG interpretation in an impressive 92.9% of cases. The model showed exceptional strength in integrating clinical context (85.1% positive assessments), demonstrating sophisticated reasoning capabilities over raw sensor data.

[AGI] Meta Superintelligence Labs introduces MetaEmbed, a late-interaction recipe for multimodal retrieval that exposes a single control surface at serving time: how many compact “Meta Tokens” to use on the query and candidate sides. Rather than collapsing each item into one vector (CLIP-style) or exploding into hundreds of patch/token vectors (ColBERT-style), MetaEmbed appends a fixed, learnable set of Meta Tokens in training and reuses their final hidden states as multi-vector embeddings at inference. The approach enables test-time scaling—operators can trade accuracy for latency and index size by selecting a retrieval budget without retraining......
[Open Source & Compact Device Models] Liquid AI Releases LFM2-8B-A1B: An On-Device Mixture-of-Experts with 8.3B Params and a 1.5B Active Params per Token. How much capability can a sparse 8.3B-parameter MoE with a ~1.5B active path deliver on your phone without blowing latency or memory? Liquid AI has released LFM2-8B-A1B, a small-scale Mixture-of-Experts (MoE) model built for on-device execution under tight memory, latency, and energy budgets. Unlike most MoE work optimized for cloud batch serving, LFM2-8B-A1B targets phones, laptops, and embedded systems. It showcases 8.3B total parameters but activates only ~1.5B parameters per token, using sparse expert routing to preserve a small compute path while increasing representational capacity. The model is released under the LFM Open License v1.0 (lfm1.0)....

[AGI-Open-Source-Agentic] Sentient AI Releases ROMA: An Open-Source and AGI Focused Meta-Agent Framework for Building AI Agents with Hierarchical Task Execution. ROMA structures agentic workflows as a hierarchical, recursive task tree: parent nodes break a complex goal into subtasks, pass them down to child nodes as context, and later aggregate their solutions as results flow back up—making the context flow transparent and fully traceable across node transitions. ROMA defines a minimal, recursive control loop. A node first atomizes a request (atomic or not). If non-atomic, a planner decomposes it into subtasks; otherwise, an executor runs the task via an LLM, a tool/API, or even a nested agent. An aggregator then merges child outputs into the parent’s answer. This decision loop repeats for each subtask, producing a dependency-aware tree that executes independent branches in parallel and enforces left-to-right ordering when a subtask depends on a previous sibling…..
