Validation on 11 RTX 3090 GPUs (2026-09-14)
The IMMA checkpoint scored 100/100 on a fixed suite of controlled image
fixtures; the matched BF16 vision reference scored 99/100. This is a
regression check, not a general vision benchmark. Eight simultaneous requests
with eight distinct images each completed. A stretched-image stress variant
completed with identical counting errors in four of eight requests in both
variants.
The IMMA runtime completed a 990,160-token image prompt. Its repeated prompt
reused 989,952 tokens (99.979%) through LMCache. A separate image replay after
restarting all model/cache pods recovered 5,120 tokens from Redis on every
rank with initially empty local caches. Redis capacity was bounded to 12 GiB;
full long-context persistence in Redis is not claimed.
Minimum sampled free GPU memory across startup and tested IMMA workloads was
1.161 GiB per GPU or greater. Configured limits were 1,000,000 context tokens,
eight concurrent sequences, and eight images per request. Production SM86 PTX
verified signed INT8 tensor-core MMA in vision linear and attention kernels.
