  1. OpenAI, Anthropic accused of borrowing DeepSeek tech without credit

    An English op-ed and an X user's screenshot allege that OpenAI's and Anthropic's recent cache price cuts came from adopting DeepSeek's cache optimization without acknowledgment. The Chinese outlet Huxiu's Kanjian Lab checked the figures and found the price cuts themselves are documented — Claude Opus 5.5's cache-read price fell from $0.50 to $0.20 per million tokens versus Opus 5, and GPT-6.1 Sol's cache input is $0.10 per million tokens — but pricing tables do not establish technical provenance, and the original author provided no code or company statement, with the percentage drop also shifting depending on the baseline used. DeepSeek's V4.1 Flash technical report says its global KV cache footprint is reduced roughly 437x versus early V1 at the same context length, about a quarter of the previous V4 Flash. The piece also notes that NVIDIA's Nemotron Nano 2 report explicitly credits DeepSeek's FP8 training recipe, while Anthropic in February accused DeepSeek, Moonshot and MiniMax of improperly obtaining Claude capabilities and acknowledged distillation is common industry practice.

  2. SemiAnalysis: Anthropic subscriptions offer ~5x OpenAI's API-equivalent value

    SemiAnalysis estimates that at the mid-tier model level — Claude Opus 5.5 versus GPT-6.1 Sol — Anthropic subscriptions deliver roughly 5x the API-equivalent value of OpenAI's, while top-tier limits are broadly similar across GPT-6 Astra and Fable 5.1. It estimates Anthropic's subscriptions are only ~10% of revenue but consume over 40% of inference compute, cutting blended revenue per MW by about $36M. OpenAI last week halved the API-equivalent value of its $200 tier and added a $500 tier that offers only 21% more Astra usage than the old $200 plan, with pre-cut $200 plans keeping old limits until October 29; SemiAnalysis also launched a subscriptions dashboard tracking OpenAI, Anthropic, Meta, SpaceXAI, Cursor, Cognition, Z.ai, MiniMax and Moonshot.
