T6 slashes KV cache 10x via TPA
The T6 architecture introduces Tensor Product Attention (TPA), a novel mechanism that uses dynamic tensor decomposition to compress KV caches by 10x. By factorizing Query, Key, and Value representations into contextual low-rank components, T6 maintains high model quality and native RoPE compatibility while drastically reducing the memory overhead of long-sequence inference.
// ANALYSIS
TPA effectively solves the "RoPE tax" that hindered previous low-rank attention methods like DeepSeek’s MLA, making extreme context compression viable for standard Transformer architectures.
- –10x memory reduction allows for massive context windows on consumer-grade hardware that previously hit OOM limits.
- –Seamless RoPE integration enables TPA to be a drop-in replacement for Llama-style models without the complexity of decoupled heads.
- –Custom FlashTPA Triton kernels ensure that theoretical memory gains translate into actual wall-clock inference speedups.
- –Matches or exceeds the performance of GQA and MLA in perplexity benchmarks, proving that higher-order tensor factorization preserves more semantic signal than simple matrix rank reduction.
