Mlx generate text, by default halusonates more

Issue Description
Problem: When using the mix generate text command with verbose set to false, and the following parameters:

Temperature: 0.1 or 0
Top p: 1
The LLM models seem to hallucinate more frequently.

Models Used:

Mistral 7B v3
IBM Granite
Mistral 7B v2
Use Case: Text-to-SQL

Method Used: mlx.generate_text

Steps to Reproduce
Set up the environment with the specified models.
Run the mix generate text command with verbose set to false.
Use a temperature of 0.1 or 0 and top p of 1.
Observe the output for hallucinations.
Expected Behavior
The models should generate accurate and coherent SQL queries without hallucinations.

Actual Behavior
The models produce outputs that are factually incorrect or nonsensical, indicating hallucinations.

Additional Information
Dataset: 20,000 examples split for training and validation.
Hardware: 128GB M3 Max

Start by reproducing the issue with mlx.generate_text using verbose=false, temperature 0 or 0.1, top_p 1, and the listed Mistral or Granite models. Compare the generated Text-to-SQL output against the reported behavior and determine whether the difference is caused by the command, generation settings, or model setup. Done requires a reproducible cause and a defined correction or documented limitation.
