The primary differentiator in developer workflow design is context retention capacity. Claude Mythos 5 offers a context window of 2,000,000 tokens, while Gemini 3.1 Pro supports up to 2,000,000 tokens.
Both models offer equivalent context window sizes, which means their fit is determined primarily by pricing structure and operational latency.
Evaluating pricing metrics is critical for running high-frequency background cron workflows.For input queries, Claude Mythos 5 costs $8.00 per 1M tokens, compared to $1.25 per 1M tokens for Gemini 3.1 Pro.
Gemini 3.1 Pro is the more cost-effective choice for input prompts, yielding savings of 84% compared to Claude Mythos 5. Similarly, output generations are cheaper on Gemini 3.1 Pro ($5.00 vs $32.00), representing a savings of 84% on completion tokens.
Gemini 3.1 Pro is better for large document parsing due to its larger context capacity of 2,000,000 tokens, enabling it to fit approximately 1x more content than Claude Mythos 5 in a single prompt.
Gemini 3.1 Pro is more budget-friendly for prompt inputs, costing $1.25 per million tokens (a saving of 84%). For output completion tokens, Gemini 3.1 Pro is more cost-effective ($5.00 per 1M tokens).
