# Llama 3.1 70B Instruct vs Llama 3.1 405B

Put two to four models side by side on the fields that decide a deployment: context, price, region, license, languages, hosting, and what is verified.

Where two models differ, this table shows the difference and stops. LLM EU publishes no winner badge without a documented score for that task, and a missing figure stays missing instead of becoming a zero.

## When to use it

### [Llama 3.1 70B Instruct](/en/models/llama-3-1-70b-instruct/)

#### Strengths

- open weights are published on Hugging Face and can be downloaded without a vendor agreement
- the model page lists 6 languages the European Union publishes in, including en, de, fr, it
- instruction-tuned checkpoint with a chat template in the repository

#### Limits

- catalogue only %E2%80%94 LLM EU does not run this model, and nothing on this card implies an LLM EU endpoint
- no evaluation has been run by LLM EU
- the published configuration records no context window, so the card carries none
- at 70.6B parameters, self-hosting needs a high-memory accelerator

#### Tasks

[Multilingual support](/en/tasks/multilingual-support/), [Reasoning](/en/tasks/reasoning/), [Summarisation](/en/tasks/summarization/)
