What happened
A blog post on insufferable.dev argues the competitive dynamic between Western and Chinese AI labs has flipped: instead of Western labs accusing Chinese labs of distilling their models, Western labs are now quietly adopting Chinese inference optimizations. It cites DeepSeek's KV cache work — MLA at roughly 15x compression, then Compressed Sparse Attention and Heavily Compressed Attention, and DeepSeek-V4.1-Flash with CSA2, cross-layer cache reuse and FP4 caching bringing the global KV cache to 890 bytes per token, roughly 437x below DeepSeek-V1 — and claims Claude Opus 5.5 and GPT-6.1 Sol shipped with these techniques, with Opus 5.5 cutting cache-read pricing 60% versus Opus 5. The excerpt is truncated mid-sentence, and the pricing claims and model-release details are asserted by the author without cited primary sources.
Why it matters
If the cache-read price cuts described here are real, the cost of running long-context coding and agent sessions shifts from output tokens toward a much cheaper cache-read line item, which changes how you'd budget and architect retrieval-heavy agents. But the article gives no links to DeepSeek's papers or to Anthropic/OpenAI pricing pages, so before repricing anything, verify the 890 bytes-per-token figure and the claimed 60% Opus cache-read reduction against the vendors' own docs — the HN thread (349 points, 368 comments) is a better starting point than the post itself.
Discussion angle
Pull your own LLM bill and split it into cache-read versus output tokens for a long-context agent workflow — does a 60% cache-read cut actually move your total, or is output still the dominant cost?
