	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
