Temporally Ordered Pre-training Improves LLM Factual Freshness (Kairos)
Researchers from Kyutai pre-train 6B-parameter models on temporally ordered Common Crawl snapshots and compare them against standard shuffled pre-training baselines. They introduce a benchmark of over 7,000 temporally grounded questions to evaluate whether models correctly associate facts with their corresponding time periods. Results show sequentially trained models match shuffled baselines on general language understanding while exhibiting more up-to-date and temporally precise factual knowledge. Code, checkpoints, and datasets are released under the Kairos project.
Claude Code Source Code Leaked, Revealing Architecture and Unreleased Features
Anthropic's Claude Code version 2.1.88 accidentally included a source map file that allowed decoding of over 512,000 lines of closed-source code across 1,900 files, which was published widely before Anthropic removed the package. Analysis of the leaked code reveals Claude Code's architecture as a modular, OS-like agent system with swarm subagents, a three-tier memory structure, and multi-stage context compression. The leak also exposed unreleased features including an always-on background agent called Kairos with a memory-pruning subsystem called autoDream, a voice interface, an 'undercover mode' for stealth git commits, and references to unreleased models codenamed Capybara and Numbat. Anthropic confirmed the leak was a packaging error and not a security breach, with no user data exposed.
