f8f4678ee4 feat: benchmark local Ollama models against 50 tok/s threshold (#287)
Some checks failed
Forge CI / smoke-and-build (pull_request) Failing after 1m24s
Add scripts/benchmark_local_models.py — tests all local Ollama models
against the 50 tok/s UX threshold (configurable via --threshold).

Features:
- Auto-discovers all pulled Ollama models or test specific ones
- Configurable rounds, max tokens, threshold
- Per-round timing with prompt_eval/eval token breakdown
- Human-readable table report with PASS/FAIL/ERROR status
- JSON output mode (--json) for CI integration
- Exit code 1 if any model fails threshold

Usage:
  python3 scripts/benchmark_local_models.py                 # all models, 3 rounds
  python3 scripts/benchmark_local_models.py --models qwen2.5:7b  # single model
  python3 scripts/benchmark_local_models.py --json          # CI output
  python3 scripts/benchmark_local_models.py --threshold 30  # custom threshold

Tested: gemma3:1b scores 141.8 tok/s (PASS).
