DECISION FACTORS
What materially changes the choice.
Context capacity
Both publish a 1,048,576-token context window.
Input modalities
Both list PDF, audio, image, text, video as input types.
Direct token cost
For 100K uncached input + 10K output tokens, both calculate to $0.1125 at the catalog verification date.
HOW TO DECIDE
Specifications narrow the field. Your workload decides.
Context, modalities and direct token economics are comparable from official sources. Coding quality, latency, reliability and agent success should be measured on your own acceptance tests before production routing.
Replay real tasks
Use representative prompts, files, tools and expected outputs from the workload you plan to ship.
Measure task cost
Include retries, cached tokens, long-context rules and tool charges—not only headline input price.
Track failures
Record hallucinations, tool errors, timeout behavior and human corrections alongside pass rate.
Route by task
A portfolio can outperform a one-model policy when different task classes have different cost and capability needs.
