[nitpick] This line exceeds typical line length conventions (appears to be over 100 characters). Consider breaking the ternary operator across multiple lines for better readability.

Suggested change

	String modelName = "DeepSeek-R1-Distill-Qwen".equals(basename) ? "DeepSeek-R1-Distill-Qwen" : "Qwen2.5";
	String modelName = "DeepSeek-R1-Distill-Qwen".equals(basename)
	? "DeepSeek-R1-Distill-Qwen"
	: "Qwen2.5";

[nitpick] This line is excessively long (over 150 characters) and reduces readability. Consider breaking it into multiple lines or extracting the conditional logic into a separate variable.

Suggested change

	int numberOfKeyValueHeads = metadata.containsKey("qwen2.attention.head_count_kv") ? (int) metadata.get("qwen2.attention.head_count_kv") : (int) metadata.get("qwen2.attention.head_count");
	int numberOfKeyValueHeads;
	if (metadata.containsKey("qwen2.attention.head_count_kv")) {
	numberOfKeyValueHeads = (int) metadata.get("qwen2.attention.head_count_kv");
	} else {
	numberOfKeyValueHeads = (int) metadata.get("qwen2.attention.head_count");
	}

[nitpick] This constructor call with multiple parameters on a single line is difficult to read and maintain. Consider formatting each parameter on a separate line for better readability.

Suggested change

	vocabulary.size(), modelContextLength, contextLength, false, (float) metadata.get("qwen2.attention.layer_norm_rms_epsilon"), (float) metadata.get("qwen2.rope.freq_base"));
	vocabulary.size(),
	modelContextLength,
	contextLength,
	false,
	(float) metadata.get("qwen2.attention.layer_norm_rms_epsilon"),
	(float) metadata.get("qwen2.rope.freq_base")
	);
