Build a Model Benchmarking & Evaluation Workflow with a Live Comparison Harness
In 2026 model capability moves weekly — Gemini 3.7 Flash jumped 16 points on DeepSWE in three weeks, GLM-5.3 hit 84.5% on CyberGym, and the frontier leaders reshuffle every release. Static model choices are obsolete. This workflow builds a LangGraph evaluation harness that runs your real workloads against candidate models, scores them on task-specific metrics, tracks scores over time, and produces the evidence that routing and procurement decisions need.
