Summary

DeepSeek: DeepSeek V4 Flash Vision Exp does not yet carry a Known Good Index score — the index needs at least one science, one mathematics and one coding result. It accepts text, image input, outputs text, and supports a 1.05M-token context window.

Pricing is $0.44 per 1M input tokens (below the $2.08 average) and $1.32 per 1M output (below the $9.56 average). Cached input reads at $0.014 per 1M, a 97% discount on its input price. At 88 tokens per second it sits in the fastest quarter of the models we track.

Price & Cost

Published API pricing by token type

BlendedInput vs outputQuality per dollar
Blended Price

USD per 1M tokens at a 3:1 input:output blend. Live from OpenRouter, cross-checked against models.dev. Lower is better. Ranked against the 439 models priced above zero, which is the population the chart draws; excludes 29 published at no cost (free and promotional tiers).

The Known Good
We publish blended price rather than cost-per-task. Cost-per-task requires token counts from an evaluation suite we do not run. Blended price is computed from published rates and is fully reproducible — see the pricing methodology.

Context Window

Maximum input tokens accepted
