The companies that make the stuff flat out say that it's not a lubricant.
The two companies I know of off the top of my head that make anti seize clearly call it a lubricant.

There may be some companies making anti seize with "ground up quartz crystals" in it, and stating it's not a lubricant, but clearly not all of them are.
By the way, for what it's worth, lime (calcium oxide) is a common component of many greases.

"Introduced in the 1940s, anti-seize lubricants have evolved far beyond their original use as high-temperature lubricants. Anti-seize compounds are made for high-temperature applications to facilitate easier removal of threaded fasteners fasteners
In construction, connectors between structural members. Bolted connections are used when it is necessary to fasten two elements tightly together, especially to resist shear and bending, as in column and beam connections. by preventing seizing and galling, but the ability of these lubricants doesn't end there. For example, anti-seize lubricants:
* may be even more important when torquing fasteners down than when backing them off
* are valuable for low-temperature applications, as well as harsh, corrosive environments
* are not just for threaded fasteners; some compounds can improve gasket performance or lubricate a variety of plant equipment
* provide smooth assembly and reduce torque tension scatter, which leads to more uniform bolt tensions.
Know the material
Above 350[degrees]F, conventional petroleum-based lubricants vaporize , leaving fastener threads vulnerable to corrosion and seizing. Anti-seize compounds were developed to solve the problem of fastener seizure in high-temperature equipment. Still on the market today, the earliest anti-seize compounds consisted of copper flakes or copper powder suspended in grease. When the grease disappears, the copper particles remain, protecting the threads and allowing easy disassembly.
More recent formulations follow the same principle but use different materials to suit specific needs. Now, special formulations exist for extremely high temperatures for use with stainless-steel fasteners, soft-metal fasteners, in food production facilities and in nuclear power plants. Fillers in these formulations can include copper, nickel, zinc, aluminum or non-metallic materials such as graphite, calcium fluoride calcium fluoride,molybdenum disulfide, calcium hydroxide, zinc oxide,or calcium oxide."
