TraceDiff: Autoregressive Latent Diffusion for High-Fidelity Storage I/O Trace Synthesis

I/O traces are essential for storage system evaluation and workload analysis, but real traces are often scarce due to privacy concerns, collection costs, and workload diversity. While LSTM-based generators model short-term sequential dependencies, they suffer from autoregressive error accumulation and struggle to joint...

KAT-Coder-V2.5 Technical Report

We present KAT-Coder-V2.5, a coding-focused agentic model trained to act autonomously inside real, executable repositories rather than as a single-turn code generator. Its capability is bottlenecked less by model scale than by the scarcity of reproducible environments, verifiable rewards, and high-value trajectories, w...
