## Tracked benchmark scores

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| BullshitBench v2 | 6% | [BullshitBench](https://github.com/petergpt/bullshit-benchmark) | 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. |

## About Qwen3

Qwen3 was introduced on April 29, 2025 with eight initial open-weight models under Apache 2.0. The lineup included six dense sizes from 0.6B to 32B and two mixture-of-experts models, 30B-A3B and 235B-A22B. The initial checkpoints combined thinking and non-thinking behavior in the same weights.

The release emphasized multilingual coverage and reasoning for mathematics, code and tool use. Developers could switch thinking modes and manage the computation spent on a response. The initial hybrid models should be distinguished from later Qwen3 checkpoints released specifically as Instruct or Thinking variants.
