# ana-ml2 GPU0 char-rp prose seat (MeroMero-v2). Real .env lives on the host.
#
# ⚠ GPU0 IS SHARED WITH `vllm-gen` AND THE BUDGETS MUST SUM UNDER ~0.92.
# gen runs at --gpu-memory-utilization 0.43 but actually holds ~45.6 GiB of the
# 94.97 GiB card, because the utilization figure sizes the KV cache and does not
# cover CUDA context, graphs and non-torch overhead. This seat was at 0.51:
# 0.43 + 0.51 = 0.94, which left ~0.6 GiB of real headroom and worked right up
# until it did not. On 2026-08-24 it stopped fitting and the seat entered a
# crash-loop — 13 restarts, `torch.OutOfMemoryError: ... 195.19 MiB is free`,
# both the `char-rp` and `char-rp-reasoning` gateway aliases returning 500s
# (they share this one seat; see the LiteLLM routes for :8016).
#
# 0.47 restores a real margin (~4.8 GiB free on the card) and costs nothing you
# can use: KV cache goes 27.36 GiB -> 23.56 GiB, which is 430,825 -> 371,023
# tokens against a max-model-len of 262,144. The pool still holds 1.4x a
# full-length sequence; what you lose is concurrent long requests, not context.
#
# Raising this again means lowering gen's in the same change. Check the real
# numbers, not the flags: `nvidia-smi --query-compute-apps=pid,used_memory`.
#
# ⚠ AND CHECK THEM ON A FRESHLY-RESTARTED gen. Measured 2026-08-24: gen held
# 46,726 MiB (45.6 GiB) after ~3 days of uptime, and 39,424 MiB (38.5 GiB)
# immediately after a restart — the same container, the same
# `--gpu-memory-utilization 0.43`, ~7 GiB apart. Its footprint GROWS WITH
# UPTIME, which is the missing half of why this seat "fit on the 21st and
# stopped fitting on the 24th": nothing about this seat changed, gen crept up
# underneath it. Headroom arithmetic done against a long-running gen is
# measuring a moving number.
