What Mistral’s docs calledmistral-medium-latest
On 12 June 2026, Mistral’s docs paired this alias with Mistral Medium 3.1 (mistral-medium-2508). Four days later, they paired it with Mistral Medium 3.5 (mistral-medium-3-5). The exact live switch time is unknown. These revisions don’t show when routing changed, whether it varied by account or region, or what any customer was billed.

The documented change
The table keeps the three Mistral documentation states separate. The 2 September 2026 revision still contains the newer name, fixed identifier and price.
On a narrow screen, scroll the table sideways to see every column.
| Revision | Model | Fixed identifier | Normalized USD price | Sources |
|---|---|---|---|---|
5b47202 | Mistral Medium 3.1Label: Deprecated | mistral-medium-2508dated API identifier | $0.40 input / $2.00 output per million tokens | SourceRevision |

The newer target had higher documented prices
The two model records also carried different price fields: $0.40 input / $2.00 output per million tokens for the older target and $1.50 input / $7.50 output per million tokens for the newer one. That is 3.75× for input and 3.75× for output.
The 2 September 2026 source still listed Mistral Medium 3.5 as mistral-medium-3-5 at the same USD amounts, with the source label “GA.”
Sources and method
Every source link is pinned to a Git revision. That makes the documentation state reproducible without turning a commit time into a claim about the live service.
How I checked this record
This is a manual comparison of source files at pinned revisions. A source revision time says when that repository state was committed. It does not say when a production alias changed. Historical entries are backfilled from Git, so AI-Buzz did not observe the live service at those times.
Mistral’s pinned 2 September 2026 lifecycle policy defines a major/minor identifier such as mistral-medium-3-5 as fixed and says moving aliases may switch automatically. We do not apply that policy retroactively to infer historical routing. The older mistral-medium-2508 is described here as a dated API identifier, not a major/minor identifier.
The historical model files contain numeric prices per million tokens but no currency field. I normalized them to USD because Mistral’s pinned historical price component renders dollars and its current pricing helper defaults to USD.
