Your Agent Keeps Forgetting Because You Keep Switching Models

Three weeks ago, the fastest-growing model on r/LocalLLaMA had no name. The community called it ox-alpha, a stealth release nobody officially claimed. People benchmarked it blind and argued about who built it, then added it to their agent stacks anyway. On August 26 the mask came off: ox-alpha is GLM-5.3-Flash (320B params, 18B active, MIT).

That same month, Qwen shipped five releases in 36 days. If you run AI agents, that's a maintenance problem your roadmap didn't budget for.

The churn tax

Every model swap makes an agent that "remembers" via context pay again: prompts need retuning, tool calls need retesting, and the context you curated evaporates. If memory lives in the model, model churn is memory loss. Weekly releases make it a weekly tax.

Memory that outlives the model

We built Uteke on the opposite bet: models are commodities, memory is the asset. One local binary, SQLite plus a vector index, no server. Any model reads the same memory via MCP or CLI, so your agent's brain survives every swap. The README numbers: 42ms P50 recall at 10K memories, Recall@5 0.946 on LongMemEval.
