via “result caching with configurable ttl and eviction policies”

Self-hardening prompt injection detector with multi-layer defense.

Unique: Implements configurable in-memory caching with multiple eviction policies (LRU, LFU, FIFO) and per-request cache bypass options, allowing developers to balance latency, cost, and memory usage; cache key includes configuration state to prevent incorrect hits when settings change

vs others: More sophisticated than simple TTL-based caching by supporting multiple eviction policies and configuration-aware cache keys; reduces API costs for repetitive workloads without requiring external cache infrastructure

via “response caching system with pickle serialization”

Graduate-level expert QA — unsearchable questions in biology, physics, chemistry for deep reasoning.

Unique: Caches at the API response level (full model outputs) rather than at the question level, allowing post-hoc changes to answer parsing and evaluation logic without re-running inference. Uses question ID + configuration tuple as cache key, enabling the same question to be evaluated with different model settings while maintaining cache hits for identical configurations.

vs others: More flexible than result-level caching because it preserves raw model outputs, allowing researchers to change evaluation metrics or answer parsing logic without re-querying the API, whereas caching only final scores requires re-inference if evaluation criteria change.
