What the record shows

We have observed one change to Devstral Small's rates since it entered our archive on 2026-02-23. The most recent, on 2026-09-19, left the output rate unchanged.

Against the 40 models we price, it is the 3rd cheapest for retrieval-shaped work, which reads a great deal and writes little, and the 4th cheapest for content-shaped work, which does the reverse. The two are close, so it holds its position whichever way your workload leans.

It charges 3.0 times more for output than for input, against a median of 5.0 times across the set. That is narrower than most, so it punishes long answers less than the typical model does.

Inside Mistral's own lineup it is the 3rd cheapest of the 9 models we track on this workload, so 2 cheaper and 6 more expensive options sit on the same account behind the same key.

28 of the 40 models we price offer a larger context window, and 2 match it exactly. Context is a capability limit rather than a cost one: paying more buys no extra room unless the larger window is what you are paying for.

Cached input reads at $0.010 against a standard input rate of $0.100, a 90% discount on the part of your prompt that repeats.

Whether it accepts image input is not stated in the source we capture, and we do not guess at it.

Its 256k token context window holds roughly 192,000 words of English text in a single request. A workload that does not fit cannot run here at any price, which is a capability limit rather than a cost one.
