The pilot plant has started to process material, this is new correct?

After some more process improvement tests, it is this material from the Gen3 not the Gen4, that will be sent to potential buyers correct ? In the release it says:

"The goal of the QRR Pilot plant program is to attain a point where the system can be operated 24/7 which is the time required to collect all information necessary to advance to the next phase, which is building a commercial sized GEN4 PUREVAPTM QRR system. During this phase, the system will produce High Purity Silicon material on a semi continuous mode. Importantly, at this step HPQ will be sending the bulk of its samples to potential buyers"

I don't get it
