With the recent rapid advancement of Agentic Intelligence, agentic tool use in LLMs has become increasingly important. During multi-turn interactions between agents and users, the dynamic, uncertain, and stochastic nature of user demands poses significant challenges to the agent's tool invocation capabilities. Agents are no longer expected to simply call tools to deliver a result; rather, they must iteratively refine their understanding of user needs through communication while simultaneously invoking tools to resolve user queries. Existing reinforcement learning (RL) approaches for tool use lack the integration of genuinely dynamic users during the RL training process. To bridge this gap, we introduce MUA-RL (Multi-turn User-interacting Agent Reinforcement Learning for agentic tool use), a novel reinforcement learning framework that, for the first time in the field of agentic tool use, integrates LLM-simulated users into the reinforcement learning loop. MUA-RL aims to enable autonomous learning of models to communicate with users efficiently and use various tools to solve practical problems in dynamic multi-turn interactions. Evaluations are done on several multi-turn tool-using benchmarks (see Figure 1). Specifically, MUA-RL-32B achieves 67.3 on TAU2 Retail, 45.4 on TAU2 Airline, 28.3 on TAU2 Telecom, 28.4 on BFCL-V3 Multi Turn, and 82.5 on ACEBench Agent -- outperforming or matching the performance of larger open-source models such as DeepSeek-V3-0324 and Qwen3-235B-A22B in non-thinking settings.

Most tech costs a fair chunk of change (the PS5 Pro and iPad Pro jump to mind), but some smaller electronics are (almost) as exciting. Now that Cyber Monday is here, we've found dozens of deals on inexpensive electronics and accessories that cost less than 50. Unlike other lists you may find today, this one is made up of items we've tested, reviewed or otherwise recommend in our buying and gift guides -- so we think they're actually worth your money. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere. Anker Nano Charger 30W USB-C for 13 ( 7 off): This compact 30-watt wall charger is smaller than others of its wattage and can speedily juice up an iPhone or Android handset. Anker is one of Engadget's most recommended accessory brands and this is the model we picked for our fast charger guide. Get the same deal at Anker with an auto-applied code. Anker Nano power bank with built-in USB-C connector for 16 ( 4 off): It's the size of an old-timey lipstick case but packs enough juice (and its own USB-C plug) to get a dying smartphone back in service with at least a half charge.

The expensive tech gets all the attention -- thousand-dollar phones and 500 tablets. But the supporting players, the cables and batteries and chargers that make those devices work properly, are just as important. Right now for Black Friday, many of those smaller gadgets are on sale for less than 50 even after the day has passed. And there are even some standalone devices like earbuds and smart speakers that fall well below the threshold. We've tested scads of these smaller, less expensive tech for Engadget buying guides, including the best power banks, iPad accessories, smart plugs and microSD cards. Here, we've gathered up all the Black Friday tech deals under 50 that you can still get on gadgets we recommend. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere.

When it comes to new tech, 50 doesn't get you a lot-- except perhaps during Black Friday sales. Surprisingly, quite a few of the smaller electronics and accessories we recommend are currently on sale right now for less than 50. These deals include picks from our guides to accessories guides, portable batteries, budget earbuds and smart speakers. Everything on this list has earned the Engadget nod of approval -- like Anker's Nano charger ( 13), Belkin's AirTag holder ( 15) and PopSocket phone grips ( 15). These picks come from stuff we tested for our reviews and buying guides or from personal use and brands we know to be reputable -- so you don't have to guess whether these Black Friday tech deals are worth your (less than) 50.
