The SaaS founder LLM cost trap

You ship an AI feature. 100 users sign up. Your OpenAI bill goes from $20 to $400 in 1 month. Each user costs you $4 + your $20 SaaS price. You're at -$3.80 margin per user.

With Brainiall Pro Team $99/mo + 50k credits = ~10k AI calls covered = ~100 active users at near-zero marginal cost. Margin: +$15/user.

Per-tenant architecture

# Multi-tenant pattern — track usage per customer
from openai import OpenAI

# Your master key
master_client = OpenAI(
    base_url="https://api.brainiall.com/v1",
    api_key="brnl-master-..."
)

# Or generate per-tenant keys via dashboard
# Each tenant gets independent brnl- key with scoped usage tracking

# In your handler:
def chat_for_user(user_id, message, tenant_id):
    response = master_client.chat.completions.create(
        model="claude-sonnet-4-6",
        messages=[{"role": "user", "content": message}],
        # Tag with tenant_id for usage analytics
        user=f"tenant_{tenant_id}_{user_id}"
    )
    return response.choices[0].message.content

# In admin dashboard (via Brainiall API):
# GET /api/admin/usage?tenant=tenant_42
# Returns: tokens, requests, cost per tenant for billing markup
