Vision et images en entrée

Envoyez des images aux modèles multimodaux : encodage, limites de taille et coût.

Les modèles Claude et Gemini acceptent des images en plus du texte. Les images sont des blocs de contenu à l’intérieur d’un message ordinaire.

Image en Base64

Copy{
  "model": "claude-sonnet-4-6",
  "max_tokens": 1024,
  "messages": [{
    "role": "user",
    "content": [
      {"type": "image", "source": {
        "type": "base64",
        "media_type": "image/png",
        "data": "iVBORw0KGgoAAAANSUhEUg..."
      }},
      {"type": "text", "text": "What does this chart show?"}
    ]
  }]
}

Python

Copyimport base64, anthropic

img = base64.standard_b64encode(open(class="s">"chart.png", class="s">"rb").read()).decode()

client = anthropic.Anthropic(api_key=class="s">"sk-your-key", base_url=class="s">"https://aiprimetech.io")
