TL;DR

• Qwen3-235B-A22B-2507 (released July 2025) is the updated version of Qwen3-235B-A22B (April 2025).
• Two separate model variants are now available:
  • Thinking model
  • Instruct model
• This marks a shift from the hybrid “Thinking” mode used in previous releases.
• From the Qwen team (source):

  “After talking with the community and thinking it through, we decided to stop using hybrid thinking mode. Instead, we’ll train Instruct and Thinking models separately so we can get the best quality possible.” “A small update to Qwen3-235B-A22B, but a big improvement in quality!”

​

Highlights:

• Released: July 2025
• 235B total parameters / 22B active (Mixture of Experts architecture)
• Native 262K token context window
• Strong performance on math, logic, and coding tasks
• Outperforms Kimi K2 (1T params) and Claude Opus 4 (Non-Thinking) in several key benchmarks
• Try it on Nebius AI Studio

Fun Fact

Qwen3-235B-A22B-2507 uses a Mixture of Experts (MoE) architecture with 235B total parameters — but only 22B are active at any given time! So you get massive model performance with much lower compute costs. Smart and efficient.

​

Artificial Analysis Benchmark

According to Artificial Analysis, Qwen3 is currently the top-performing open-source model — and it’s getting close to matching proprietary SOTA models. Source

Fun Benchmark: “Pelican riding a bicycle”

Inspired by Simon Willison’s fun experiment (see here), this benchmark is all about how well models generate quirky, imaginative responses. Prompt:

Generate an SVG of a pelican riding a bicycle

You can see our full pelican tests here. So how does gpt-oss do? Let’s see.
