Handling Large Volatile Corpora with AI
How frontier labs and practitioners handle large, fast-churning corpora (codebases under daily churn, financial filings, clinical records, log streams) across 2025-2026: layered architectures that cache stable prefixes, route volatile content through hybrid lexical-plus-AST-plus-vector retrieval with explicit version metadata, push heavy reprocessing to discounted batch APIs, and confront the still-unsolved problem of cache and index invalidation when the corpus changes daily.

Full brief
Read the synthesised summary→
Large volatile corpora, codebases under daily churn, financial filings, clinical records, log streams, broke the assumption underlying first-generation retrieval-augmented generation: that documents are stable and that semantic similarity beats exact matching. By mid-2026, frontier labs and practitioners have…

Handling large volatile corpora with AI requires orchestrating multiple systems—caching, retrieval, incremental indexing, and selective fine-tuning—each with distinct tradeoffs. The recent research landscape reveals three interconnected challenges: first, how…

Frontier Lab & Model News
Frontier labs have deployed prompt caching as a standard feature across major APIs by 2026, with Anthropic, OpenAI, and Google all offering 50-90% input cost reductions and 13-85% latency improvements for cached prefixes. A 2026 study across 500+ agent…
