Summary

DeepSeek: DeepSeek V4 Pro 0813 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 input, outputs text, and supports a 1.05M-token context window.

Pricing is $1.12 per 1M input tokens (below the $2.08 average) and $3.35 per 1M output (below the $9.56 average). Cached input reads at $0.037 per 1M, a 97% discount on its input price. At 51 tokens per second it sits in the upper middle of the tracked range.

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

Context Window

Maximum input context from provider metadata via models.dev and OpenRouter. Higher is better.

Latency

Time to first token, mean across providers over successful measurements from the last 48 hours

Latency (TTFT)

Seconds to first streamed chunk, mean across tracked providers over successful measurements from the last 48 hours. Derived from OpenRouter endpoint telemetry. Lower is better.
