tl;dr: Summary not available
HN Discussion:
  • ↓Reduced context size is a dealbreaker; long context is essential for detailed work and papers
  • ↑Large contexts degrade model quality anyway, so the reduction is fine or even beneficial
  • ~Compaction is lossy and problematic; better to manually manage context via chunking or clearing
  • ↑Codex's compaction works seamlessly in practice, so the reduction isn't noticeable
  • ↓OpenAI should adopt cheaper KV cache techniques (like DeepSeek) rather than shrinking context
