The best-benchmarked open-source AI memory system.

Key details

  • The only official sources for MemPalace are this GitHub repository, the PyPI package, and the docs site at mempalaceofficial.com.
  • Any other domain — including mempalace.tech — is an impostor and may distribute malware.
  • Details and timeline: docs/HISTORY.md.
  • Verbatim storage, pluggable backend, 96.6% R@5 raw on LongMemEval — zero API calls.

Results & evidence

  • Verbatim storage, pluggable backend, 96.6% R@5 raw on LongMemEval — zero API calls.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

Key details

  • Unlike function-level code generation, it requires the model to understand the entire repository, reasoning over complex dependencies across functions, classes, and modules.

  • In this paper, we introduce InlineCoder, a novel framework for repository-level code generation.
  • InlineCoder enhances the understanding of repository context by inlining the unfinished function into its call graph, thereby reframing the challenging repository understanding as an easier function-level coding task.

Key details

  • Having one idle while working on the other felt like underutilization of resources.
  • Initially the goal was to do file transfer via local network, and then came running commands.
  • I then tried running coding agents from one machine to the other, and it worked.

    Later I figured there should be a better way to continue my claude sessions remotely on my phone from the gym.

  • So I did a cloudflare worker that connects to my local machine.
