🛈 IMPORTANT!!!

You will need to search for, download, and load the model qwen3-coder-next in LM studio. You will also need to start the API server and generate an API Key. Learn how to configure LM Studio here.

Notes for using qwen3-coder-next:

• This model is 80B (requires high memory) and it is fairly fast.

• Although it's purpose is coding I included created a civitai workflow for this model as it won me first place in a civitai.com daily challenge.

• If the workflow appears to hang on the LM Studio Prompt Enhancer node, don’t worry this is expected.

• I set max tokens to 520, the max token length for Flux 2 prompts is 512, you can lower it if you don't want the LLM to ramble.
