P0 fixes (blocking usability): - FIX-01: thread-local cuBLAS handle (was creating/destroying per matmul) - FIX-16: EOS token no longer leaks into API responses - FIX-17: max_seq_len configurable via --max-seq-len (default 2048, was hardcoded 256) - FIX-18: max_tokens clamped to available seq space, prompt overflow returns 400 P1 fixes (bugs & performance): - FIX-07: CachingAllocator wired into all hot paths (to_device, embedding, rope, concat) - FIX-08: CudaDeviceProp buffer increased to 32KB for CUDA 12.9 safety - FIX-09: tokenizer byte_fallback graceful degradation (was panic) - FIX-19: causal mask uses -INFINITY instead of -1e9 (BF16 supports inf) - FIX-20: LayerNorm rewritten to numerically stable two-pass algorithm - FIX-21: min block size guard (32 threads) for LayerNorm/RMSNorm launches P2 fixes (improvements): - FIX-22: Option<GpuKVCache> + take() eliminates dummy KV cache allocations - FIX-23: RoPE cache no longer artificially capped at 8192 positions Verified on dash5 (RTX 5090): 51 tok/s batch=1, 74 tok/s 2-concurrent, 1.7-3.3x HF transformers.
