Bottom line：Tencent released Hy Memory 2.0, an open-source memory framework, dedicated model, and local management tool designed to provide persistent agent memory.
Core Offerings：Includes the Hy Memory framework, Hy-Memory-30B-A3B dedicated model, and MemHub local application for cross-tool memory synchronization.
Performance：Ranked #1 open-source framework across four memory benchmarks, outperforming several frontier baselines.
OpenAI Upgrades GPT-6 Astra Pro with Parallel Multi-Agent ExecutionOOpenAI
Bottom line：OpenAI has rolled out an upgrade to GPT-6 Astra Pro in ChatGPT, introducing faster responses and parallel task execution by multiple agents.
New Capabilities：Allows multiple sub-agents to tackle different parts of a complex task simultaneously with trackable progress and reviewable outputs.
Availability：Currently available to Pro users within the Chat tab.
NVIDIA RTX Spark Laptops Launch with 128GB Unified Memory for Local AINNVIDIA
Bottom line：NVIDIA and major hardware partners have officially released RTX Spark PCs, pairing Blackwell RTX GPUs and Grace CPUs for heavy local AI workloads.
Hardware Specs：Features up to 128GB of unified memory and combines Blackwell architecture with Grace CPUs to support large local models and training.
Market Launch：Available starting at $2,599 from manufacturers including ASUS, Dell, HP, Lenovo, Microsoft, and MSI.
Bottom line：A new study from UC Berkeley demonstrates that periodically resetting an agent’s history and restarting from top candidates prevents anchoring and improves optimization outcomes.
Methodology：Periodically discards candidate session history and restarts search from the best performing candidate found so far.
Performance Gains：Yields up to 15% improvement over parallel agents and up to 39% over a single agent given the same total compute budget.
Google DeepMind Demonstrates End-to-End Minecraft Completion Using Gemini 4 Argon AgentsGGoogle DeepMind
Bottom line：Google DeepMind researchers showcased four Gemini 4 Argon agents autonomously completing Minecraft from scratch without human intervention.
Execution Details：Four agents coordinated via in-game chat and shared memory over 27 hours, writing 2,783 self-generated programs to defeat the Ender Dragon.
Autonomy Level：Operated entirely within a sandbox using code and text through the Mineflayer library without predefined roles or seed scouting.
