What kind of thing are you comparing?
A finished agent, a platform to build agents on, and a delivered solution are three different purchases. This directory keeps them apart, because comparing them side by side on one table mostly reveals differences in shape rather than differences in quality.
A product you can deploy and use on its own to perform a defined task.
Infrastructure for building, running or evaluating agents — you compose agents yourself rather than adopting a finished one.
An engagement or delivery-shaped offering scoped to one organisation, delivered by a solution provider.
A company that builds or delivers agents, platforms and solutions. Listed as an entity in its own right, not as a product.
Why the separation matters
Three questions a buyer asks, which a single undifferentiated list cannot answer.
A finished agent is adopted and configured. A platform is composed by your own engineers. A solution is scoped with you — none of the three has a meaningful "features" list compared against the others.
Agents are usually licensed per user or per use. Platforms are licensed as infrastructure. Solutions are priced per engagement. A single pricing row across all three is arithmetic, not comparison.
For an agent, the product vendor. For a solution, the delivery partner. The distinction is the difference between "the software has a defect" and "the programme did not land", and it decides where a dispute goes.
Solutions are not all the same thing
Four kinds of solution appear under one heading. The distinction decides whether it can be ordered, has to be adapted, is only a reference, or does not exist as a deliverable at all.
A packaged offering that can be ordered as-is.
Delivered by a vendor and adapted to the customer's environment; scope is defined per engagement.
A documented deployment that can be studied but is not itself a purchasable offering.
An approach or architecture without a purchasable deliverable.
