What happened

DeepSeek V4.1 Flash 1017 (Max) is an open‑weight model that supports text and image input, outputs text, and offers a 1 million‑token context window. It scores 33 on the Artificial Analysis Intelligence Index, well above the median of 23 for comparable models, but it is very verbose, generating 174 million tokens versus a median of 104 million. Pricing is $0.30 per 1 M input tokens and $1.20 per 1 M output tokens, costing about $0.60 per Intelligence Index task. The model takes 15.2 minutes per task, slower than the median 12.7 minutes, and is noted as moderately priced but slower than average.

Why it matters

For users choosing AI services, the model offers strong intelligence at a reasonable price but may be less efficient for time‑critical tasks due to its slower speed and high verbosity. Businesses that need large context windows and detailed outputs might find it useful, while those prioritising speed may look elsewhere.

Reality check

An automated, sceptical read of the source

Incremental. The model improves intelligence scores and offers a huge context window, yet its speed and verbosity are average‑to‑slow, making the advance modest rather than revolutionary.
