Multilingual support

All Mira models are trained on multilingual data and support over 50 languages. Special attention is given to Russian and English, which are supported at native-speaker level.

Supported languages

Priority languages (highest quality)

Well-supported languages

The following languages are supported at a high level with minimal quality loss compared to priority languages:

• European — German, French, Spanish, Italian, Portuguese, Dutch, Polish, Ukrainian, Czech, Swedish
• Asian — Chinese (Simplified/Traditional), Japanese, Korean, Vietnamese, Thai, Indonesian
• Middle Eastern — Arabic, Turkish, Hebrew, Persian
• Indian — Hindi, Bengali, Tamil, Telugu

Performance across languages

Mira models are optimized to maintain quality when working with non-English languages. Here is approximate performance by language:

Best practices for non-English prompts

• Write prompts in the target language — for best Russian output quality, ask in Russian rather than asking in English to respond in Russian
• Be specific — specify desired style and formality in the target language
• System messages — set the system message in the target language to maintain context
• Avoid mixing — for maximum quality, avoid mixing languages in a single prompt (except for technical terms)

Russian language examples

curl https://api.vmira.ai/v1/chat/completions \
  -H "Authorization: Bearer sk-mira-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "mira",
    "messages": [
      {
        "role": "system",
        "content": "Ты — опытный технический писатель. Отвечай на русском языке, используя профессиональный, но доступный стиль."
      },
      {
        "role": "user",
        "content": "Объясни, что такое REST API, простыми словами."
      }
    ]
  }'

Translation

Mira excels at translation between any supported languages. For best results, provide context and specify the target audience.

{
  "model": "mira",
  "messages": [
    {
      "role": "system",
      "content": "You are a professional translator. Translate from Russian to English, preserving the style and tone of the original."
    },
    {
      "role": "user",
      "content": "Translate: \"Artificial intelligence opens new horizons in science and technology.\""
    }
  ]
}

Language detection

Mira automatically detects the language of input text and can switch languages within a single conversation. This is useful for applications serving users from different countries.

Mixed-language conversations

Mira can handle conversations where the user switches between languages. The model responds in the same language the question was asked in, unless instructed otherwise.

{
  "model": "mira",
  "messages": [
    { "role": "user", "content": "What is machine learning?" },
    { "role": "assistant", "content": "Machine learning is a subset of AI..." },
    { "role": "user", "content": "А теперь объясни это на русском." },
    { "role": "assistant", "content": "Машинное обучение — это подраздел ИИ..." }
  ]
