Model can also have a form of mocks, description. By the broadest definition BRD is also a model. The diagram on the other hand is a graphical representation only. It's a kind of a single sheet out of the whole set of "plans".
In practice, you'll split complex information that constitutes the model into small comprehensible bits that you will show on a diagrams and sometimes also in other forms, e.
Large, complex data model will be split by packages plus few diagrams showing the complex relations. The multiple behaviours of the system will be presented one at the time you can't have a single activity diagram presenting multiple activities, can you?
The entire model of the system will be represented from various angles, both static and behavioural and shown on different models. And so on. So typically, the model will consist of a list of objects in the system, usually represented in diagrams, the behaviours, also at least partially presented as diagrams and sometimes part of information presented in additional form as a part of the documentation. Think of a house 2-storey house.
Plans of each of the house's floors will be one version or even just part of the model, second part being the physical model or system visualisation. The plans can be very generic so that you understand where the rooms are or how to run the whole infrastructure. A single plan of one floor will be a diagram.
A natural follow-up question is "What should be included in the model? As a rule of thumb though the model should contain all necessary information and not more! The diagrams are part of the model, they are a subset of it, so what is the difference between UML diagrams and UML models has no sense.

Then, by taking into consideration a number of implementation issues ranging from architectural styles, nonfunctional quality criteria to be maximized e. If your focus is on the diagram itself, there are two big differences between diagrams about domain model and diagrams about design model: At least this is what the Larman book Applying UML and Patterns says.
In UML diagrams which represent domain model, you cannot use arrows. All classes are interlinked with a line, which signifies "relation", and you should use text annotations over the lines to illustrate what relation it exactly is. While in design models, you have to use arrows, all types of arrows: association, inheritance In design model you have to specify the type of properties and methods etc, while in domain model you only have to write them without anything additional just like in real world.
