VESPA has published a new data service compiling the asteroid spectra from Gaia DR3, which is by far the largest collection available with 60,518 entries.

This complements other asteroid spectrum services, which can be cross-searched from the VESPA portal.
The service is accessible from VO tools or the VESPA portal:
