Best API & Subscription for Oh My Pi

To run Oh My Pi cost-efficiently, declare Standard Compute in ~/.omp/agent/models.yml with the openai-completions API and https://api.stdcmpt.com/v1: its router sends each step to the cheapest model that can do it (Claude Fable 5.1 or GPT-6 Astra only when it counts), and plans start at $19 a month with a $20 compute budget shared by every model role. Long sessions and parallel subagents spend that budget faster, so compare it with a coding subscription or usage-based models per role.

Light or occasional use
Use an efficient model for routine work and evaluate stronger models on tasks that need them. Compare real consumption across supported providers before treating a subscription as the cheapest option.
Daily use, cost-optimized
Standard Compute sends each omp step to the cheapest model that can do it, and for every model we vet providers for price, uptime and speed, with automatic fallback. Opt-in Europe or US Compliance rules apply per key, team or company, and we don't train on your prompts or store them. The bill is one monthly plan with a finite allowance: long sessions and parallel agents still consume compute, and requests stop at the budget.

API and subscription options for omp

OptionPriceWhat you get
OpenCode Go$10 or $40/moNative OpenCode subscription: Go $10 a month, Go Plus $40. Each model has a monthly usage limit in dollars, with 5-hour and weekly windows set as shares of it. Single-member workspaces only. Source: opencode.ai
Standard Compute (us)From $19/moSmart routing sends each request to the cheapest model that can do it, or pin any model by its exact ID. Standard Compute starts at $19/month with a $20 monthly compute budget. Requests stop when that budget is exhausted until renewal or a plan change; there are no automatic overage charges. Requests are not slowed as the budget is used. It is a fixed bill with a finite allowance.

Try one task before choosing a plan

  1. Check the API format and model configuration supported by your installed omp version.
  2. Run a small task on a clean branch and review the result, elapsed time and compute used.
  3. Estimate your actual monthly workload before selecting a larger allowance.

Disclosure: this guide is maintained by Standard Compute, one of the options above. Choose based on task quality, supported features and total cost for your workload. Light usage may cost less on a usage-based API; sustained workloads need enough allowance on any subscription.
