        10. Common Mistakes

    *   *Introduction:* Acknowledge the frustration of "jittery" local inference. Set the stage for a systematic "Scientific Method" approach.

    *   *Quick Diagnosis:*
        *   Check: KV Cache size, Context Window, Batch Size, GPU vs. CPU offloading.
        *   Identify "First Token Latency" (TTFT) vs. "Token Generation Speed" (TPOT).
        *   Explain why GPU memory jumps happen (Dynamic KV cache, context growth).

    *   *Data Collection Plan:*
        *   Tools: `nvidia-smi` (or `rocm-smi`), `llama.cpp` logs, Flight Recorder (request/response times), ServerTop (system metrics).
        *   Methodology: Baseline tests (fixed prompt, fixed length).
        *   Variables to hold constant: Temperature, Top_P, Max Tokens, Context.

    *   *MTP Comparison Plan:*
        *   What is MTP? (Multi-Token Prediction).
        *   How to test: Compare a model with MTP enabled vs. disabled (or a non-MTP version of the same architecture).
        *   Metrics: Throughput (tokens/sec) vs. Perplexity/Quality.
        *   The "Self-Deception" check: Don't just look at speed; look at the *quality* of the output at that speed.

    *   *Reasoning Budget Plan:*
        *   Define "Reasoning" (Chain of Thought).
        *   How to measure: Tokens spent on "thinking" vs. "answering."
        *   Cost analysis: Is the extra latency worth the accuracy?

    *   *Long Output Test Plan:*
        *   Testing context degradation.
        *   Testing "Lost in the Middle."
        *   Measuring "Time to Completion" for 1000+ tokens.

    *   *SQLite Queries:*
        *   Assume a schema for the Flight Recorder/SQLite reports.
        *   Queries for: Average TTFT, P95 Latency, Tokens per Second per Request, Memory usage correlation.

    *   *Dashboard Screenshots To Capture:*
        *   Describe what the charts should look like (Time-series of VRAM, TTFT distribution, Token/sec stability).

    *   *Weekend Checklist:*
        *   Step-by-step schedule (Saturday morning: Baseline, Saturday afternoon: MTP, Sunday: Analysis).

    *   *Interpreting Results:*
        *   Decision matrix: Coding (High reasoning, low speed tolerance), RAG (High context, medium speed), Chat (Low latency, high speed), Creative (High variety, medium speed).

    *   *Common Mistakes:*
        *   Variable context (dynamic vs. fixed).
        *   Ignoring system noise (background processes).
        *   "Cherry-picking" the best run.

    *   *Expansion Strategy:* To hit the 9,000-token target, I need to go deep into *why* these things happen.
    *   *Technical Depth:* Explain the mechanics of KV Cache, the difference between Prefill and Decode phases, and how MTP affects the attention mechanism.
    *   *Practicality:* Provide actual `curl` commands for testing and specific `llama.cpp` flags.
    *   *Formatting:* Use clear headings, tables, and code blocks.

    *   *Quick Diagnosis:* Focus on the "Why." Why does memory jump? (Dynamic KV cache allocation). Why is the first token slow? (Prefill phase complexity).
    *   *Data Collection:* Detail the Flight Recorder setup. Explain how to sync timestamps between `nvidia-smi` and the inference logs.
    *   *MTP:* Explain that MTP is about predicting multiple tokens in one forward pass. Compare "MTP-enabled" vs "Standard" and look for the "Speedup vs. Accuracy" trade-off.
    *   *Reasoning Budget:* This is crucial for agentic workflows. How much "thinking" can we afford before the user gets bored?
    *   *SQLite:* Write complex queries (e.g., `GROUP BY` for different models or `AVG` for different context lengths).
    *   *Decision Matrix:* Create a clear table for Coding, RAG, Agentic, Chat, Creative.

    *   *Check:* Did I include the required sections? Yes.
    *   *Check:* Is the tone helpful? Yes.
    *   *Check:* Is the length sufficient? I need to ensure the descriptions are verbose and detailed. I will elaborate on the "Reasoning Budget" and "Long Output" sections significantly, as these are often overlooked.
    *   *Check:* Are the SQL queries useful? I'll assume a standard `requests` table with `start_time`, `end_time`, `tokens_in`, `tokens_out`, `model_name`, and `vram_usage`.
