Dimension-by-dimension analysis
Reasoning & overall intelligence
DeepSeek-V4-Pro leads the overall aggregate by 9 points (77 vs 68). That is a meaningful, not marginal, edge on hard, multi-step reasoning, while Doubao Seed Evolving remains a strong generalist that is not out of its depth on routine work.
Agentic coding
This is a clear gap: DeepSeek-V4-Pro scores 79 against 67. On multi-file edits, SWE-style tickets and long-horizon agent loops DeepSeek-V4-Pro needs fewer correction turns; Doubao Seed Evolving is still competent for scripts and assisted completion but trails as task complexity rises.
Multimodal
Doubao Seed Evolving leads multimodal 83 vs 77. A concrete modality difference: Doubao Seed Evolving additionally handles image. Neither emits native video, so the comparison is about parsing images and documents, not generation.
Speed & latency
DeepSeek-V4-Pro is faster in interactive use: ~70 tok/s with 0.5s TTFT versus ~60 tok/s with 0.5s TTFT (about 1.2× the throughput). For conversational UIs where perceived responsiveness drives retention, that edge is a real product factor even when raw reasoning is lower.
Context: window vs usable recall
Nominal windows are 1M for DeepSeek-V4-Pro and 1M for Doubao Seed Evolving. Effective-context scores point the same way as window size — DeepSeek-V4-Pro is ahead on usable recall (94 vs 92), so prefer it for long-document work where details cannot be missed.
Price & total cost
DeepSeek-V4-Pro is the cheaper API at $0.44/$1.32 versus Doubao Seed Evolving at $0.83/$4.17 per 1M input/output tokens — list input is about 1.9× lower.
Chinese vs English
English: DeepSeek-V4-Pro 82 vs Doubao Seed Evolving 70. Chinese: 85 vs 93. For Chinese-language production, Doubao Seed Evolving is the stronger pick. Note that non-Chinese models generally require overseas network access for their APIs.
Tool use & ecosystem
Function-calling score: DeepSeek-V4-Pro 82 vs Doubao Seed Evolving 82, so DeepSeek-V4-Pro has the edge on structured tool use. Fine-tuning is available from DeepSeek-V4-Pro. Factor in existing SDK/plugin familiarity — switching cost often outweighs a few-point tool-use gap.
Cost worked example — same workload, real token math
Assume a production workload of 100M input + 30M output tokens per month, with 90% of input tokens served from cache. Figures use public list prices.
