Cohere¶

Setup¶

pip install llmgate[cohere]
export COHERE_API_KEY="..."

Model prefix¶

Always prefix with cohere/:

completion("cohere/command-r-plus", messages)
completion("cohere/command-r", messages)
completion("cohere/command-a-03-2025", messages)

Embeddings¶

Cohere has excellent embedding models:

from llmgate import embed

resp = embed("cohere/embed-english-v3.0", "Hello world")
resp = embed("cohere/embed-multilingual-v3.0", "Bonjour monde")

Vision¶

Not supported

Cohere's vision API is not yet stable. Passing image content to a Cohere model raises VisionNotSupported.

from llmgate.exceptions import VisionNotSupported

try:
    resp = completion("cohere/command-r-plus", messages_with_images)
except VisionNotSupported:
    resp = completion("gpt-4o-mini", messages_with_images)  # fallback
