ARC Releases Preview of Interactive Reasoning Benchmark ARC-AGI-3: ARC has released a preview of ARC-AGI-3, featuring three games designed to challenge interactive reasoning capabilities. Unlike the first two versions, ARC-AGI-3 focuses on evaluating agents’ reasoning abilities in dynamic environments rather than static reasoning. Currently, state-of-the-art AI scores 0% on this benchmark, while humans score 100%. ARC has also released an API for AI researchers to test their agents and is hosting an agent competition with a $10,000 prize. This release highlights the importance of interactive benchmarks in evaluating AI systems, particularly agents, and encourages community participation in building more robust AI systems.

Kimi K2 Open-Sourced, Attracting Global Attention: Kimi_Moonshot has open-sourced its trillion-parameter MoE model, Kimi K2, designed specifically for agent tasks. It excels in programming, tool calling, and mathematical reasoning, outperforming open-source models like DeepSeek-V3 and Alibaba Qwen3. K2’s release is being hailed as “another DeepSeek moment” due to its high performance, low cost, and genuinely open-source nature. The Kimi team’s active engagement with the community has fueled K2’s rapid dissemination and application, demonstrating the potential of open-source models to challenge closed-source counterparts. K2’s release not only elevates Kimi’s global profile but also brings new possibilities to fields like AI programming. (Source: TheTuringPost, ClementDelangue, cline, huggingface, 36kr)
OpenAI Releases ChatGPT Agent, a New “Model as Agent” Approach: OpenAI has released ChatGPT Agent, an AI agent capable of autonomously selecting tools and executing multi-step tasks. It integrates various tools, including a browser, terminal, and API access, and is trained end-to-end using reinforcement learning, rather than being a combination of multiple models. ChatGPT Agent achieved state-of-the-art results in multiple benchmarks and emphasizes safety and user control. While its functionality is similar to products like Manus, the difference in its technical approach suggests a development direction towards end-to-end general agents. (Source: 36kr, MatthewJBar)
