I built the save button. **[Medium](https://daily.dev/sources/medium_js)** · 6 min read · 0 upvotes · 0 comments ## Summary Slipcase is a tool that snapshots and restores LLM inference session state (KV cache and attention tensors) to disk, eliminating the need to re-read entire conversation histories on session resume. Benchmarks on an A100 with a 7B model and ~97K-token context show 19.2× faster time-to-first-token in warm conditions and 2.5–4.8× in cold-disk scenarios. The system uses a cryptographic manifest to ensure bit-exact restore fidelity, falling back to transcript replay on any mismatch. It targets self-hosted vLLM deployments with long-context, resume-heavy workloads like agent fleets and companion platforms. Limitations include dependency on fast local disks and engine-family binding of snapshots. ## Full article daily.dev links to this article rather than hosting it.
