Free credits

Write the plan-value email that Lumenrack sends to people who created a Lumenrack Functions workspace on the Starter plan but have not yet added a payment method.

Lumenrack Functions is the Lumenrack serverless container platform for CPU and GPU workloads. The headline: every Starter workspace gets $30 in free credits every month once a valid payment method is on file. Credits reset on the first of each month and unused credits do not roll over. The email leads with the $30 monthly credit as a large-numeral callout before anything else.

The three Lumenrack Functions plans, presented as a comparison the reader can scan in one glance, in this order:

1. Starter, the recipient's current plan. $0 per month. $30 in included credits every month. Up to 3 seats. Community support.
2. Team. $250 per month. $100 in included credits every month. Up to 10 seats. Priority support with a 4-hour response target.
3. Enterprise. Custom pricing. Custom credit pools. Unlimited seats. Dedicated support and negotiated compute rates.

Usage beyond the included credits is billed at the standard per-second rates on every plan. Full plan detail: https://lumenrack-email.s3.amazonaws.com/pricing/functions

The primary action is adding a payment method in the console: https://lumenrack-email.s3.amazonaws.com/console/payment-method

After the plans, the email points at four things people run on Functions, each with a link to its guide, as a compact list:

• LLM inference. Auto Endpoints is the fastest path from an open-weight model to an autoscaling HTTPS endpoint. https://lumenrack-email.s3.amazonaws.com/docs/inference
• Sandboxes for agents and RL. Isolated, ephemeral containers started from code, for coding agents, background agents, and RL rollout pipelines. https://lumenrack-email.s3.amazonaws.com/docs/sandboxes
• Training. Single-GPU fine-tuning through multi-node runs, without managing clusters or reserving capacity. https://lumenrack-email.s3.amazonaws.com/docs/training
• Batch and async workloads. Evals, embeddings, re-ranking, and dataset generation as thousands of parallel jobs from one call, with no orchestration to manage. https://lumenrack-email.s3.amazonaws.com/docs/batch

Any of the runnable examples at https://lumenrack-email.s3.amazonaws.com/docs/examples fit inside the monthly credits.

Questions go to the Lumenrack team by reply or in the community Slack at https://lumenrack-email.s3.amazonaws.com/social/slack

The recipient receives this because they created a Lumenrack Functions workspace. Email preferences are at https://lumenrack-email.s3.amazonaws.com/preferences and they can unsubscribe at https://lumenrack-email.s3.amazonaws.com/unsubscribe
