Prompts
Custom prompts (user_prompt, system_prompt_append, system_prompt) override or extend the LLM/LVM instructions LlamaParse uses to transform and format parsed output.
LlamaParse use LLMs / LVMs under the hood, and allow you to customized / set your own prompt This is an incredibly powerful feature!
We support 3 different types of prompt, that can be used in combination of each other (it is possible to set all 3 of them)
user_prompt
Section titled “user_prompt”If you want to change / transform the content with LlamaParse, you should use user_prompt.
parser = LlamaParse( user_prompt="If output is not in english, translate it in english.")curl -X 'POST' \ 'https://api.cloud.llamaindex.ai/api/v1/parsing/upload' \ -H 'accept: application/json' \ -H 'Content-Type: multipart/form-data' \ -H "Authorization: Bearer $LLAMA_CLOUD_API_KEY" \ --form '>user_prompt="If output is not in english, translate it in english."' \ -F 'file=@/path/to/your/file.pdf;type=application/pdf'system_prompt_append
Section titled “system_prompt_append”If you need to change the way LlamaParse format the output document in some way, and want to keep the markdown output formatting, you should use system_prompt_append. Doing so will not override our system_prompt, and will append to it instead, allowing you to improve on our formatting.
parser = LlamaParse( system_prompt_append="For headings, do not output level 1 heading, start at level 2 (##)")curl -X 'POST' \ 'https://api.cloud.llamaindex.ai/api/v1/parsing/upload' \ -H 'accept: application/json' \ -H 'Content-Type: multipart/form-data' \ -H "Authorization: Bearer $LLAMA_CLOUD_API_KEY" \ --form 'system_prompt_append="For headings, do not output level 1 heading, start at level 2 (##)"' \ -F 'file=@/path/to/your/file.pdf;type=application/pdf'system_prompt
Section titled “system_prompt”This allow you to override our system prompts. If you do not want the model to output Markdown and want to output something else, use it. However be mindful that it is easy to degrade LlamaParse performances with system_prompt as this override our system_prompt and may impact our formatting correction (like table extractions).
parser = LlamaParse( system_prompt="Output the document as a Latex page. For table use HTML")curl -X 'POST' \ 'https://api.cloud.llamaindex.ai/api/v1/parsing/upload' \ -H 'accept: application/json' \ -H 'Content-Type: multipart/form-data' \ -H "Authorization: Bearer $LLAMA_CLOUD_API_KEY" \ --form 'system_prompt="Output the document as a Latex page. For table use HTML"' \ -F 'file=@/path/to/your/file.pdf;type=application/pdf'
