DeepSeek V4 Pro vs Hy3 Preview

Updated August 7, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.

DeepSeek V4 Pro

DeepSeek

60.0/100

Supported · Public rank #52

90% interval 41.7–78.3

Hy3 Preview

Tencent

42.8/100

Estimated · Public rank #167

90% interval 32.9–52.7

DeepSeek V4 Pro has the higher public score estimate, 60.01 versus 42.8, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.

6 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Agentic work

    Tool use, computer use, and multi-step task completion

    DeepSeek V4 Pro

    DeepSeek V4 Pro leads on the same 1 weighted benchmark row.

    Confidence: limited

  • Long documents

  • Coding work

    Code generation, repair, and software-engineering tasks

    Not enough matched evidence

    The category averages use different weighted benchmark sets, so they are directional rather than like-for-like.

What is actually comparable

Shared results can support a head-to-head reading. Results present for only one model describe coverage, not superiority.

Category results, on a stated basis

Each row states whether both averages use the same weighted benchmark set. Directional and not-comparable rows remain visible, but they never receive a winner in this template.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

Too few matched category axes support a radar. The ruled list below shows only shared benchmark results; positions use each benchmark’s normalized display scale when available.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Frequently asked questions

Which is better, DeepSeek V4 Pro or Hy3 Preview?

DeepSeek V4 Pro has the higher public score estimate, 60.01 versus 42.8, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, DeepSeek V4 Pro or Hy3 Preview?

The current coding averages use different weighted benchmark sets, so BenchLM does not name a winner from them. Read the shared benchmark rows directly and test the models on the same task set.

Which is better for agentic tasks, DeepSeek V4 Pro or Hy3 Preview?

DeepSeek V4 Pro leads the like-for-like agentic tasks comparison across 1 shared weighted benchmark row.

Which costs less, DeepSeek V4 Pro or Hy3 Preview?

Both models do not have comparable published API token rates, so this page does not name a universal price winner.

Which has the larger context window, DeepSeek V4 Pro or Hy3 Preview?

DeepSeek V4 Pro has the larger documented context window: 1M, compared with 256K.
