I came across "semi free form" and "open die forging" but in Polish publications. Not sure which option is correct.

semi-closed die forging
Polish translations used semi-free, which cannot be found in western publications.
Open-die forging provides NO confinement of metal flow, so it is not półswobodne, which does.

Closed die forging — The shaping of hot metal completely within the walls or cavities of two dies that come together to enclose the workpiece on all sides. The impression for the forging can be entirely in either die or divided between the top and bottom dies. Impression-die forging, often used interchangeably with the term closed-die forging, refers to a closed-die operation in which the dies contain a provision for controlling the flow of excess material, or flash, that is generated. By contrast, in flashless forging, the material is deformed in a cavity that allows little or no escape of excess material. See Impression Die Forging.

2.3 Semi closed die forging operation
Only drop hammer type of force application is possible.
In case of open die and closed die forging operations the volume of raw material required is remaining same as that of the volume of final finished component. But in case of closed die forging operation the volume of the raw material is about 10% to 20% more than final component to be obtained.
To accommodate the excess volume of material it is required to provide some open space dies also called gutter.
Because of provision of gutter the flash is produces in the forged component.
This flash is unwanted material which has to be removed by trimming operation.
Flash and gutter is used only in case of closed die operation but not in open die or semi closed die forging operation.

open-die forging
Open-die forging is also known as smith forging. In open-die forging, a hammer strikes and deforms the workpiece, which is placed on a stationary anvil. Open-die forging gets its name from the fact that the dies (the surfaces that are in contact with the workpiece) do not enclose the workpiece, allowing it to flow except where contacted by the dies. - https://en.wikipedia.org/wiki/Forging#Open-die_drop_forging

Kucie półswobodne - polega na częściowym ograniczaniu swobodnego płynięcia metalu podczas wywierania nacisku narzędziem na część powierzchni przedkuwki. - https://pl.wikipedia.org/wiki/Kucie_półswobodne

Open-die forging, also known as free forging or smith forging, is the process of striking a hammer and deforming a workpiece, which is placed on a stationary anvil.
The piece of metal is deformed between “dies,” which are usually flat and don’t enclose the metal completely. - https://cantondropforge.com/open-vs-closed-die-forging/
