I serve unsoloth GGUF models with ollama, both codex and vscode copilot are throw no function calling/tools support error, it works fine in openweui. such as https://huggingface.co/unsloth/Qwen3-Coder-Next-GGUF/blob/main/Qwen3-Coder-Next-UD-IQ4_NL.gguf.

TL;DR

• The issue may be resolved by checking the compatibility of the GGUF models with the ollama, codex, and vscode copilot tools.

Guidance

• Verify that the GGUF models are correctly formatted and compatible with the tools being used.
• Check the documentation for ollama, codex, and vscode copilot to ensure that they support the GGUF model format.
• Test the GGUF models with other tools or environments to isolate the issue.
• Compare the configuration and setup of openweui, where the models work fine, with the current setup to identify potential differences.

Notes

• The lack of information about the OS, GPU, CPU, and ollama version may limit the ability to provide a more specific solution.
• The issue may be related to a specific version or configuration of the tools being used.

Recommendation
