Lovable has released OJ, a preview engine written from scratch in Rust. It reads your existing vite.config.ts and runs real Vite plugins through a compatibility layer, all in a single binary, with no toolchain installed into the project.
Why it matters: Lovable rewrote its preview engine OJ in Rust, sharing cold start and memory comparisons against Vite, plus canary data from production.
Terminal-Bench has released version 2.0 and the Harbor package. The former is a more rigorously validated, harder benchmark for evaluating agents; the latter is for evaluating and optimizing agents. Harbor rewrites Terminal-Bench's test harness, supports deploying containers in the cloud, provides rollout interfaces for RL and SFT, and works with any agent you can put in a container.
Why it matters: Terminal-Bench 2.0 and Harbor are released together, so readers can see how the agent evaluation benchmark is validated and how to scale it in the cloud.
Terminal-Bench 新增 parallelize-graph 和 feal-linear-cryptanalysis 两个高难度任务，分别要求智能体用 Unified Parallel C 实现基因组组装的并行 de Bruijn 图构建，以及对 FEAL 类分组密码实施已知明文线性密码分析攻击。
