Capabilities & modalities

EuroLLM is a text-only multilingual language model for European-language generation, assistant tasks and machine translation. Per aggregated benchmarks and the technical report (ev-tech-report, ev-moonlight) it is the strongest for its size on multilingual EU-language tasks - on par with Gemma-2-9B on multilingual benchmarks, ahead on WMT24++ translation, and matching Mistral-7B on English - while remaining, at 9B, below frontier on raw single-language reasoning. Choose EuroLLM when you need broad, even EU-language coverage from a European, Apache-2.0 model more than you need class-topping English reasoning.

Context window & long-context behaviour

Both EuroLLM-9B and EuroLLM-1.7B use a 4,096-token context window. This is short by current standards, so design around it:

Chunk long inputs and use retrieval rather than stuffing large documents into the prompt.
Budget the 4k across system prompt, few-shot examples, input and output.

Treat 4k as the architectural ceiling.

Prompt format & chat template

The Instruct variants ship a chat template in their tokenizer configuration (with BOS token id 1 and EOS token id 4). Use it rather than hand-rolling role markers:

messages = [
    {"role": "system", "content": "You are a helpful multilingual assistant."},
    {"role": "user", "content": "Traduis en portugais : ..."},
]
inputs = tok.apply_chat_template(messages, tokenize=True,
                                 add_generation_prompt=True, return_tensors="pt")

Base checkpoints have no chat template - they are plain text-completion models and should not be prompted as chat assistants.

Language coverage

This is EuroLLM's defining strength. It is trained from scratch for multilingual EU coverage: all 24 official EU languages - Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Irish, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish, Swedish - plus roughly 11 additional strategic languages: Arabic, Catalan, Chinese, Galician, Hindi, Japanese, Korean, Norwegian, Russian, Turkish and Ukrainian.

Unlike English-centric open models where non-English behaviour is incidental, EU-language coverage is EuroLLM's design target, and translation quality (WMT24++) is a documented strength. The practical caveat: with 35 languages sharing a 9B (or 1.7B) budget, quality is uneven - the smaller and lower-resource languages trail the majors - so evaluate each target language for your task rather than assuming uniform quality.

How this scores

The ownership factor this domain covers, drawn from the one entry record.

ReliabilityIs it reliable and good enough for the job?

Moderate

Runs dependably, but per-language safety coverage is thin and uneven, so you supply the safety layer.

How this scores (AOI sub-dimensions)

Operational4/5how practical it is to run, serve and maintain in productionStandard safetensors with a conventional architecture load on all mainstream stacks (vLLM, llama.cpp, Ollama, TGI, transformers); community GGUF / MLX / GPTQ quants and a hosted NVIDIA NIM endpoint exist.

Safety3/5whether misuse risks are evaluated and guardrails are providedThe Instruct variants are instruction-tuned on EuroBlocks and behave as ordinary safety-tuned assistants, but published safety/alignment coverage is light, there is no companion guard model, and multilingual coverage means safety behaviour varies by language and is not uniformly evaluated.

What this means for adoptionYou fully own the use of these Apache-2.0 weights - clean across 9B, 1.7B and 22B-Instruct-2512, with unconditional commercial use and no field-of-use limits - and, self-hosted and EU-domiciled, you keep your data entirely. It stays short of full because data openness is partial rather than full: the SFT set (EuroBlocks-SFT-2512) is released but the ~4T-token pre-training corpus is only described, so you can inspect the recipe but not reproduce it from a released corpus as with a fully-open model; the 9B size, 4k context and uneven multilingual safety also cap reliability. Adopt it for multilingual EU-facing work that fits inside 4k, behind your own guardrails; look elsewhere for a long-context or frontier engine.

EuroLLM base and Instruct weights - 9B, 1.7B and 22B-Instruct-2512 - are distributed under OSI-approved Apache-2.0 with unconditional commercial use and no field-of-use limits (the licence is not a preference-alignment/safety grant, and the cards warn the models may hallucinate).
