Comparing Models Beyond Price: Context, Vision and Reasoning
The cheapest model is only a bargain if it can do the task. Comparing capabilities — context window, vision, reasoning, tool use — alongside price keeps you from underspending into a model that cannot deliver.
Capabilities set the shortlist
Filter first by what the job requires: a big context for long documents, vision for images, reasoning for hard logic, tool use for agents. Only models that clear those bars belong in your price comparison.
Then let price decide
Among the models that can do the job, compare cost on your workload. This two-step approach — capability filter, then price — avoids both overpaying for unused power and underspending into failure.
