feat(aiperf): qualify native text conversation history - #1804
Conversation
Forward ordered text messages through the existing TextConversation SDK. Keep Qwen chat rendering and tokenization family-owned, and reuse published AIPerf multi-turn loading with live assistant responses and explicit think time. Verify every original user turn and retained native answer by conversation and request identity, and report client and Task timings per turn. Existing models, bundles, core contracts and numerical criteria remain unchanged. Refs: NVIDIA#1679 Signed-off-by: Yizhuo Zhang <yizhuoz@nvidia.com>
Count explicit encoded token IDs from the rendered pinned template and group live turns by their correlation ID. Preserve the upstream request ordinal without using it as a conversation identity. Signed-off-by: Yizhuo Zhang <yizhuoz@nvidia.com>

- Around line 161-162: Update verify_records to reject every profiling
correlation group that does not contain both turns, in addition to the existing
measured-pair coverage check. This must reject extra incomplete groups even when
duplicate session-and-turn pairs leave the measured set unchanged.

Current head Local checks on this head passed: 756 app tests (two existing optional skips), 52 focused/detached tests, 307 source tests, both unchanged full Qwen correctness cases on the served FP16 bundle, and the real PyPI AIPerf 0.13.0 workload. All six conversations / twelve measured turns plus two separate warmup requests verified original inputs, live assistant history and native outputs, with zero errors. The optional Dev Community CI run remains queued and has no model result. It is not being represented as green or as a model failure. Merging once the unchanged required checks are satisfied, following the owner's existing merge policy used for the earlier stages. No model contracts, numerical criteria, CI configuration or merge rules were changed. |

Post-merge CI clarification for tested head The exact-head required automated premerge gate and Stable Community CI remain successful. The existing Qwen3-0.6B full FP16 bundle was verified locally on GB300 with both requested unchanged full owning cases executed non-skipped, followed by actual published AIPerf 0.13.0 qualification: six two-turn conversations: twelve measured requests plus two warmups, all fourteen history/input/output/native joins verified with no errors. The PR retains the tested revision, bundle/checkpoint identity and commands. This is a coordination/provisioning result, without an observed model-correctness or OOM test result. No model/test criterion, exclusion, CI configuration or merge rule is changed, and the optional Dev run is not counted as passing. |
Background
Closes #1679. Chat requests with several turns previously could not deliver complete history to the native text Task. This adds the conversational workload after merged stage A (#1803).
Exit Criteria
Implementation
Qwen binds the existing native
TextConversationcontract for its supported ChatML templates. Qwen owns role rendering, tokenization and prior-thinking removal, checked against the pinned Hugging Face template. The generic worker forwards typed messages and advertises the capability. The HTTP server accepts bounded text histories, forwards all roles/content, and rejects unsupported history streaming, tools or non-text messages. Existing single-turn generation and streaming retain their existing paths.The optional profiler uses AIPerf's existing
multi_turnloader. A workload configuration for the existing full Qwen3-0.6B FP16 profile selects six distinct fitting ShareGPT human/assistant/human prefixes. It sends the two original human strings and retains the actual model answer for the second request; source assistant answers are not replayed. The second turn has 50 ms think time. Verification joins phase/correlation/request identities, original user strings, actual prior assistant output and native hashes. Complete rendered history is counted using the pinned tokenizer. Server records retain hashes/counts/roles, without raw message text.No new checkpoint, model spec/manifest, native Task contract, ABI, bundle format, dependency, numerical criterion or CI gate is added. Rebuild the native server and Qwen runtime library for history support; existing engine bundles can be reused.

Current head:
8187eb46d2f2959c617d20805dcfba4110e3126e. Review found that an extra incomplete profiling correlation group could evade set coverage; the verifier now requires both turns in every profiling group. Regression coverage rejects that extra group after full original coverage and preserves intentionally partial warmup. The review conversation is fixed and resolved.The app, source, detached-review and exact-bundle PyPI results below were rerun on this head.

Six conversations were selected from twelve considered source rows; five lacked a valid alternating prefix and one exceeded the budget.Not Run / Remaining Gaps
Remote CI is pending on the current head. The review finding is fixed, verified and resolved; CodeRabbit is green. Local hardware qualification covers the existing Qwen3-0.6B FP16 pilot on GB300. Other families, hardware/precisions, history streaming, tools, media and structured reasoning are not qualified here. Native input counts remain unavailable; tokenizer counts are reported explicitly. Timing is descriptive for this fixed workload, not a capacity claim.
Contributor Self-Review
Notes For Future Readers
Review Qwen's family-owned formatter/binding first, then capability-based worker/HTTP dispatch and conversation verification. No other family or shared model semantics changed. Existing single-turn rendering and native generation math are preserved. AIPerf carries actual previous answers, so complete history must fit the bundle; no prior turn is silently dropped. Stages C–F follow in separate PRs after this merges.
Risk level
This adds a native history path and bounded HTTP support. Existing Task contracts and single-turn behavior are preserved, while protocol controls, reference-template byte parity and full-model correctness cover the new path.
