+
+## `standard_v3_0`
+
+- [216 possible tool's outputs](./standard_v3_0/README.md).
+- Overall same average accuracy of `standard_v2_1`, ~99%.
+- Inference speed: ~2ms (~3x faster than `standard_v2_1`, ~20% faster than `standard_v1`).
+
+## `standard_v2_1`
+
+- [Support for 200+ content types](./standard_v2_1/README.md), almost double what supported in `standard_v1`.
+- Overall average accuracy of ~99%.
+- Inference speed: ~6.2ms, which is slower than `standard_v1`; See `fast_v2_1` in case you need something faster (at the price of less accuracy).
+
+## `fast_v2_1`
+
+- Similar to `standard_v2_1`, but significantly faster (about 4x faster).
+- Overall average accuracy of ~98.5%.
+
