Jev in production › Agent context and memory
Hermes memory provider that asks Jev to judge every eligible memory against short criteria from the calling agent and returns the matching evidence, with no embeddings. On 120 LongMemEval-S questions final-answer errors fell 72.6% (author).
Jev-powered memory for AI agents. Try it on Hermes. Replace Mnemosyne while keeping your existing SQLite database, memory banks, and tool calls.
An independent 120-question LongMemEval-S experiment reduced final-answer errors from 62 to 17 (72.6%), using the same GPT-5.6 Luna caller with high reasoning effort. Accuracy rose from 48.3% to 85.8%. These are results for a frozen predecessor of this release, not a fresh validation of the renamed package or an official leaderboard score.
