transformers v5: summarization/translation/question-answering/text2text pipelines removed — use text-generation

Fix
# before
summarizer = pipeline("summarization")
summarizer(text)

# after: a chat model + text-generation
from transformers import pipeline
gen = pipeline("text-generation", model="HuggingFaceTB/SmolLM3-3B")
out = gen([{"role": "user", "content": f"Summarize:\n{text}"}], max_new_tokens=200)
print(out[0]["generated_text"][-1]["content"])

For VLMs, put images inside the message content list instead of passing images=. For image generation use Diffusers.

Symptom

pipeline("summarization"), pipeline("translation_en_to_fr"), pipeline("text2text-generation"), pipeline("question-answering") or pipeline("image-to-image") fail on transformers v5; v4-era tutorials still show them.

Cause

transformers v5.0.0 (2026-01-26): question-answering and Text2TextGenerationPipeline "including its related SummarizationPipeline and TranslationPipeline, were deprecated and will now be removed"; image-to-image was removed too. Image-text-to-text pipelines no longer accept images as a separate argument alongside chats.

Verify

The text-generation pipeline returns a chat transcript whose last message is the assistant reply.
