[bug] langextract still asking for API key on local Ollama API setup

[Kishlay-notabot]

result = lx.extract(
    text_or_documents=input_text,
    prompt_description=prompt,
    examples=examples,
    model_id="Qwen3:0.6b",
    model_url="http://localhost:11434",
    fence_output=False,
    use_schema_constraints=False
)

The inference out of langextract works perfectly, but it throws the API key error when this is ran.

also tried this:

result = lx.extract(
    text_or_documents=input_text,
    prompt_description=prompt,
    examples=examples,
    model_id="gemma2:2b",
    model_url="http://ollama:11434",
    fence_output=False,
    use_schema_constraints=False
)

print(result)

and from #7 I tried setting the OLLAMA_HOST env variable but that didn't fix it too.

I used this:
`from langextract import inference

result = lx.extract(
text_or_documents=input_text,
prompt_description=prompt,
examples=examples,
model_id="gemma2:2b",
model_url="http://localhost:11434",
language_model_type=inference.OllamaLanguageModel, # ✅ class, not string
fence_output=False,
use_schema_constraints=False
)`

I used this: `from langextract import inference

result = lx.extract( text_or_documents=input_text, prompt_description=prompt, examples=examples, model_id="gemma2:2b", model_url="http://localhost:11434", language_model_type=inference.OllamaLanguageModel, # ✅ class, not string fence_output=False, use_schema_constraints=False )`

sorry,still error

Hi, same issue for openai; thanks @soleimanian for the workaround!

Thx to @soleimanian. This works for me:

from langextract.inference import OllamaLanguageModel

            extracted_events_result = lx.extract(
                text_or_documents=combined_content,
                prompt_description="What ever you wish here....",
                model_id="gemma2:2b",                      
                model_url="http://localhost:11434",  # Ollama URL
                examples=self.events_extraction_examples,
                language_model_type= OllamaLanguageModel,
                fence_output=False,  
                use_schema_constraints=False  
            )
