Daily AI Research Briefing — February 27, 2026
The context drought. Anthropic ships 1M context window in GA, but capability plateaus drive focus to compression.
📏 The 1M Milestone
Anthropic's Claude 3.7 Sonnet now supports 1M tokens in general availability. But real-world use reveals limits: retrieval accuracy degrades, attention dilutes, costs balloon.
🔧 Emerging Solutions
- Context compression: Summarization layers reduce token count
- Memory architectures: External state management
- Selective attention: Routing to relevant context windows
- Two-agent patterns: Split context across sessions
💡 Lab Takeaway
Context windows are not infinite working memory. Smart compression and architectural patterns matter more than raw token count.
