Inferencex Data

Setup

Download the latest database dump from GitHub releases. It is xz-compressed and split into one or more .tar.xz.part* files; reassemble them by piping cat through xz (requires xz):

gh release download --repo SemiAnalysisAI/InferenceX-app --pattern 'inferencex-dump-*.tar.xz.part*' --dir .
cat inferencex-dump-*.tar.xz.part* | xz -d -T0 | tar -x

Data

Each .json file corresponds to one database table.

Relationships

• benchmark_results[].config_id -> configs[].id
• benchmark_results[].workflow_run_id -> workflow_runs[].id
• benchmark_results[].server_log_id -> server_logs[].id (nullable)
• eval_results[].config_id -> configs[].id
• eval_results[].workflow_run_id -> workflow_runs[].id
• run_stats[].workflow_run_id -> workflow_runs[].id
• changelog_entries[].workflow_run_id -> workflow_runs[].id

Config Fields

Each config is a unique serving deployment:

id, hardware, framework, model, precision, spec_method, disagg, is_multinode,
prefill_tp, prefill_ep, prefill_dp_attention, prefill_num_workers,
decode_tp, decode_ep, decode_dp_attention, decode_num_workers,
num_prefill_gpu, num_decode_gpu

• tp: tensor parallelism, ep: expert parallelism, dp_attention: data parallel attention, num_workers: pipeline parallel workers
• spec_method: speculative decoding method. mtp = multi-token prediction, none = standard autoregressive
• disagg=true means prefill and decode run on separate GPU pools (disaggregated serving). When disagg=false, prefill and decode fields are identical
• Total GPU count = num_prefill_gpu + num_decode_gpu for disagg, or just num_prefill_gpu for non-disagg. When not explicitly set, defaults to tp * ep

Benchmark Result Fields

id, workflow_run_id, config_id, benchmark_type, date, isl, osl, conc,
image, metrics, error, server_log_id

• benchmark_type: currently always single_turn
• date: ISO 8601 timestamp string (e.g. 2025-10-12T00:00:00.000Z)
• isl / osl: input/output sequence length in tokens
• conc: concurrency level
• image: Docker image used for the serving framework (e.g. lmsysorg/sglang:v0.5.8.post1-cu130), null for runs before 2025-12-08
• error: null means success
• metrics: nested JSON object — access as row["metrics"]["tput_per_gpu"], not as top-level fields

Metrics Keys

All latency values in seconds. tput_per_gpu is total throughput (input+output tokens) per second per GPU.

Throughput: tput_per_gpu, output_tput_per_gpu (optional), input_tput_per_gpu (optional) TTFT (time to first token): median_ttft, mean_ttft, p99_ttft, std_ttft TPOT (time per output token): median_tpot, mean_tpot, p99_tpot, std_tpot ITL (inter-token latency): median_itl, mean_itl, p99_itl, std_itl E2EL (end-to-end latency): median_e2el, mean_e2el, p99_e2el, std_e2el Interactivity: median_intvty, mean_intvty, p99_intvty, std_intvty

New numeric metrics may appear in future dumps without schema changes — the ETL auto-captures any numeric field not reserved for config dimensions.

Eval Result Fields

id, workflow_run_id, config_id, task, date, isl, osl, conc, lm_eval_version, metrics

• task: evaluation task name (e.g. gsm8k)
• metrics: nested object with n_eff, em_strict, em_flexible, em_strict_se, em_flexible_se

Workflow Run Fields

id, github_run_id, run_attempt, name, status, conclusion, head_sha,
head_branch, html_url, created_at, run_started_at, date

• run_attempt: re-runs of the same github_run_id get incrementing attempts. When computing latest results, first filter to the highest run_attempt per github_run_id.
• conclusion: success, failure, or cancelled
• html_url: link to the GitHub Actions run

Run Stats Fields

id, workflow_run_id, date, hardware, n_success, total

• Reliability rate = n_success / total per hardware per run

Availability Fields

Denormalized table for fast date-picker lookups — one row per (model, isl, osl, precision, hardware, framework, spec_method, disagg, date) combination. Not joined by config_id; uses the raw text keys directly.

model, isl, osl, precision, hardware, framework, spec_method, disagg, date

Changelog Entry Fields

id, workflow_run_id, date, base_ref, head_ref, config_keys, description, pr_link

• config_keys: array of strings like ["dsr1-fp8-mi355x-mori-sglang"] identifying which configs changed
• pr_link: GitHub PR URL (nullable)

ETL Normalization

Framework names are normalized during ingest: dynamo-trtllm -> dynamo-trt, sglang-disagg -> mori-sglang. The dump contains already-normalized values.

Enum Values

hardware: h100, h200, b200, b300, gb200, gb300, mi300x, mi325x, mi355x model: dsr1=DeepSeek-R1-0528, gptoss120b=gpt-oss-120b, llama70b=Llama-3.3-70B-Instruct-FP8, qwen3.5=Qwen-3.5-397B-A17B, kimik2.5=Kimi-K2.5, minimaxm2.5=MiniMax-M2.5, glm5=GLM-5 framework: atom, dynamo-sglang, dynamo-trt, mori-sglang, sglang, trt, vllm precision: bf16, fp4, fp8, int4 spec_method: mtp, none

Analysis Recipes

• Load data: Parse configs.json and benchmark_results.json, join on config_id, filter out rows where error is not null.
• Latest per config: First filter workflow_runs to the highest run_attempt per github_run_id, then join to benchmark_results. For each unique (config_id, conc, isl, osl), keep only the row with the latest date.
• Pareto frontier (chip vs chip): Fix a model/concurrency/sequence length. Plot throughput (x) vs median TTFT (y) per hardware. The pareto frontier connects points that dominate all others (higher throughput AND lower latency). Sort by descending throughput, greedily collect points with improving latency.
• Pareto frontier (date vs date): Fix a hardware/model/concurrency/sequence length. Plot throughput and latency over time to see how performance evolves across benchmark dates.
