RWKV-7 beats Llama 3.2 with 3x fewer training tokens and formally exceeds TC^0

The more interesting result is architectural: RWKV-7 formally exceeds TC⁰, the complexity class bounding standard Transformers (Merrill & Sabharwal's proof in the paper). It solves state-tracking problems that fixed-depth attention provably cannot.

Inference runs in O(1) memory per token — no KV cache. The hybrid variant (RWKV-X) hits 99.8% passkey retrieval at 64K and 1.37x Flash Attention v3 throughput at 128K.

Happy to discuss the delta rule generalization, the TC⁰ proof, or the benchmark methodology — I spent 36 sources digging into the caveats.
