DeepSeek V4 Flash Just Drew a Pretty Brutal "Kill Line" on This Chart (Reddit r/LocalLLM)

Reddit interprets a historical Artificial Analysis chart as roughly a 50 index and about $0.03 per weighted task for Flash 0731.

Key data and applicable tasks

Post highlights (translated and edited)

"Kill line" sounds like clickbait, but the blue dot on the chart really earns it:

"DeepSeek V4 Flash 0731 scores about 50 on the Artificial Analysis index, at about 3 cents per weighted task. On… This is a necessary excerpt; read the original source for full context.

Another awkward detail: The current Pro preview is worse than Flash 0731 on this chart; Pro has not beaten anything on this chart so far.

Comment highlights

  • u/StupidScaredSquirrel: If models on the Pareto frontier "kill" all offline models, then most of this chart would have already been killed by other models—in reality, that's not how it works; every use case has other requirements

  • u/Subject-18: OpenAI deliberately left Mimo 2.5 out of its Luna price-cut post; hilarious

  • u/FilterJoe: Asked what "per task" actually means (whether retry tokens, task types, etc., are included)

Key conclusions

  • The "kill line" concept is similarly popular in English-speaking communities: V4 Flash 0731 achieves an AA score of about 50 at roughly 3 cents per task, occupying an advantageous position at the far lower-left of the price-performance curve

  • The post is a highly upvoted r/LocalLLM post (812 points), showing that awareness of its price-performance value has spread beyond the niche

What this supports

  • Supports a dated price–capability snapshot, provided the chart’s original definitions remain visible.

What this does not support

  • Does not support treating the community interpretation as a new experiment, current rank, or precise task cost.

Method, limits, and reproduction

The figures, task set, reasoning tier, and client conditions apply only to the listed source and collection snapshot. Different versions, harnesses, or providers must not be compared directly; undisclosed parameters remain unknown.

For a reproduction, fix the model version, provider or client, reasoning tier, tools, task-set version, sample count, and collection date, and record failures, retries, and human corrections. Full steps are in the source notes below.
