DeepSeek V3 vs Gemini 3.1 Pro
Updated July 30, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload.
Gemini 3.1 Pro has the higher public score estimate, 54.66 versus 44.15, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.
1 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.

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

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.

- Deployment change
- The models list different providers, so authentication, endpoint behavior, limits, and feature support may change.
- Quality signal
- Gemini 3.1 Pro has the higher public score estimate, 54.66 versus 44.15, but the 90% score intervals overlap.
- Workload cost
- Repository review: $0.0168 vs $0.136. Cache-heavy agent loop: $0.0304 vs $0.2.
- Context tradeoff
- Gemini 3.1 Pro has the larger documented window (1M).
Run the same representative tasks against both endpoints before changing production traffic.

Frequently asked questions
Which is better, DeepSeek V3 or Gemini 3.1 Pro?
Gemini 3.1 Pro has the higher public score estimate, 54.66 versus 44.15, 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 V3 or Gemini 3.1 Pro?
The published evidence does not provide a shared weighted coding basis for both models, so BenchLM does not name a coding winner.
Which is better for agentic tasks, DeepSeek V3 or Gemini 3.1 Pro?
The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.
Which costs less, DeepSeek V3 or Gemini 3.1 Pro?
For the stated presets, chat costs $0.00082 on DeepSeek V3 and $0.008 on Gemini 3.1 Pro; repository review costs $0.0168 and $0.136; the cache-heavy agent loop costs $0.0304 and $0.2. DeepSeek V3 does not fit this workload in one request.
Which has the larger context window, DeepSeek V3 or Gemini 3.1 Pro?
Gemini 3.1 Pro has the larger documented context window: 1M, compared with 128K.
