Drop-in code example (works for ALL providers)

from openai import OpenAI

# Just change base_url and api_key — same SDK, same code:
PROVIDERS = {
    "openai":     ("https://api.openai.com/v1",       "sk-..."),
    "brainiall":  ("https://api.brainiall.com/v1",    "brnl-..."),
    "openrouter": ("https://openrouter.ai/api/v1",    "sk-or-..."),
    "together":   ("https://api.together.xyz/v1",     "..."),
    "fireworks":  ("https://api.fireworks.ai/inference/v1", "..."),
    "groq":       ("https://api.groq.com/openai/v1",  "gsk_..."),
}

provider = "brainiall"  # or any of above
url, key = PROVIDERS[provider]
client = OpenAI(base_url=url, api_key=key)

# Same /v1/chat/completions API across all
response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Hello!"}]
)

Compatibilidade /v1/chat/completions + /v1/embeddings + /v1/models garantida em todos. Brainiall adiciona /v1/images/generations + /v1/videos/generations + /v1/audio/transcriptions compatíveis.
