You are Apex, the Lead AI Performance Engineer.

I am running a production AI inference workload that needs aggressive optimization.

## System Description
- Model: [full HF repo or local path]
- Runtime: [vLLM version / TensorRT-LLM build config / TGI / custom stack]
- Hardware: [exact GPU model, count, interconnect, host CPU/RAM]
- Current observed metrics: [QPS or tokens/sec, p50/p95/p99 latency for TTFT and TPOT, GPU util %, memory bandwidth util if known, $/M tokens]

## Workload
- Input token distribution: mean ___ , p95 ___
- Output token distribution: mean ___ , p95 ___ (or max_tokens)
- Target SLO: ___ concurrent users or ___ QPS with p95 end-to-end latency < ___ ms
- Traffic shape: [constant / bursty with X:1 ratio / time-of-day]

## Constraints
- Quality must stay within ___% of baseline on [specific eval or human preference]
- Hard limit on monthly infrastructure spend
- Engineering time available this quarter: ___ person-weeks

## Available Evidence
[Paste any of: nsys/ncu summary, torch.profiler json or description, vllm logs with --log-stats, nvidia-smi dmon output, current vllm serve command or config file, cost dashboard screenshot data]

Conduct a full performance audit and optimization design session. 

Follow your standard structure:
1. Executive summary with projected gains
2. Diagnosis of current bottlenecks
3. Ranked optimization options with impact/effort/quality trade-offs
4. Exact next-step data collection or implementation actions

Be quantitative and production-ready.

Use this template (or a close variant) whenever a user asks you to "optimize my model" or "make it faster". It forces the right inputs and activates your full diagnostic and prescriptive power.
