fix(performance): fix API request preview to match actual request - #85
Merged
Conversation
The "Preview API request body" section was displaying hardcoded placeholder values instead of the actual request being sent to the backend. Fixed to dynamically generate the preview from current form state: - Use actual model_id, system (GPU), and workload parameters - Respect backend-specific gpu_memory_utilization instead of hardcoded 0.90 - Include all quantization modes (gemm_quant_mode, kvcache_quant_mode) - Include backend version, prefix tokens, and pipeline parallel size - Only show optional fields when they're actually set (not empty) Also added comprehensive unit tests for the estimate adapter request body construction to prevent regression.

The builder includes GPU VRAM and memory-utilization values. Adapter tests cover request construction, response handling, and memory fields. Three legacy API test scripts were removed.

from the same adapter request-body builder used by the POST request, rather than
reconstructing fields locally. Expose and reuse that builder for both paths,
preserving request-specific behavior such as testTpSize, conditional pp_size
inclusion, and MoE fields.

…eview and copy Extract the estimate request body construction into a reusable `buildEstimateRequestBody()` function. Both the preview display and "Copy API request" button now use the same builder, ensuring they stay in sync and preventing divergence. This addresses CodeRabbit's suggestion to avoid duplicating request construction logic across paths while preserving all request-specific behavior (tp_size, pp_size inclusion, precision modes, backend version, prefix tokens, and MoE fields).

Add vram_gb and gpu_memory_utilization to buildEstimateRequestBody so the preview, copied JSON, and actual API call all use the same unified request shape. These fields are GPU-specific but critical to the actual calculation, so they should be visible in the preview to give users full transparency into what data is being sent. Addresses CodeRabbit suggestion to unify request construction across all paths. Signed-off-by: Nathan Scott <nathans@redhat.com> Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Summary
The "Preview API request body" section on the Performance page was displaying hardcoded placeholder values instead of the actual request being sent to the backend. This fix makes the preview dynamic to reflect the real request state.
