## Benchmark scores published at release

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| BullshitBench v2 | 14% | Lab | Given a confidently-worded but nonsensical prompt, does the AI spot that it makes no sense and push back — instead of playing along and inventing an answer? The score is how often it clearly called out the nonsense. Higher is better. |
| LiveCodeBench | 93.5% | [BenchLM](https://benchlm.ai), retrieved 2026-07-11 | Coding problems published so recently the AI can't have seen them in training — a contamination-free test of raw programming skill. Higher is better. |
| BrowseComp | 83.4% | [BenchLM](https://benchlm.ai), retrieved 2026-07-11 | Can the AI browse the web and track down hard-to-find answers? Higher is better. |
| GPQA Diamond | 90.1% | Lab | Graduate-level science questions in biology, physics, and chemistry — hard enough that subject-matter PhDs score around 65%. Higher is better. |

## About DeepSeek-V4-Pro

DeepSeek-V4-Pro, released April 24, 2026 alongside the lighter DeepSeek-V4-Flash, launched as DeepSeek's frontier open-weight flagship. It scored 90.1% on GPQA Diamond and 93.5% on LiveCodeBench — the best published competitive-coding score on this tracker at the time — with 83.4% on BrowseComp for agentic web research.

The V4 generation extended DeepSeek's consistent playbook: frontier-adjacent capability, open weights, and dramatically lower cost than closed rivals. At launch V4-Pro competed directly with the strongest proprietary models of spring 2026 while remaining freely downloadable, continuing the open-weights pressure the lab began with V3 and R1. DeepSeek later designated this build V4-Pro-Preview; the generation's next update, in July 2026, went to the Flash tier first, and the Pro tier was refreshed as V4-Pro-0813 in August 2026.
