Jinja template out of the box in GPT4All-Chat 3.6.1 (does not work)

The model does not feature a jinja chat template in its tokenizer_config.json

Jinja template made by ThiloteE (maybe works?)

{{- bos_token }}
{%- for message in messages %}
    {{- message['role'] + message['content'] }}
{%- endfor %}
{%- if add_generation_prompt %}
    {{- 'ASSISTANT:' }}
{%- else %}
    {{- eos_token }}
{%- endif %}

Recommended system prompt:

The model apparently was finetuned on this system prompt: A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
