For jcode, the Rust coding-agent harness built for many sessions and swarms, the best API for parallel agents every day is a cost-optimized OpenAI-compatible profile: run jcode provider add standardcompute --base-url https://api.stdcmpt.com/v1 --model standardcompute --api-key-stdin --set-default, and Standard Compute's router sends each step to the cheapest model that can do it (Claude Fable 5.1 or GPT-6 Astra only when it counts), on a plan from $19 a month with a $20 compute budget. jcode also signs in with Claude and ChatGPT subscriptions, which come with usage windows, and with OpenRouter or provider keys billed per token. jcode itself is free and MIT-licensed.
| Option | Price | What you get |
|---|---|---|
| Claude Pro / Max | See current plans | First-party Claude subscriptions with usage limits. Compare these for Claude Code's native workflow; a Claude subscription is separate from general Anthropic API billing. Source: claude.com |
| ChatGPT plan (Codex sign-in) | $20 Plus, $100–$500 Pro | Sign in with ChatGPT and the agent runs on Codex models within your plan's Codex allowance: five-hour windows on Plus, none on Pro, and weekly limits may apply. Only for agents that support ChatGPT sign-in. Source: learn.chatgpt.com |
| Standard Compute (us) | From $19/mo | Smart 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. |
| OpenRouter | Pay-as-you-go | Choose models and providers through one API. Usage-based pricing can suit light or bursty work; estimate long agent sessions and review current fees and limits. Source: openrouter.ai |
Prices and allowances can change. jcode's provider add flags, profile storage and auth-test come from its OAUTH.md and CLI source, and the swarm effort settings from its README, read on October 15, 2026. jcode: OpenAI-compatible API-key providers · jcode docs: providers · jcode repo.

This writes [providers.standardcompute] to ~/.jcode/config.toml and stores the key in jcode's private config directory (for example ~/.config/jcode/provider-standardcompute.env). Add --model-catalog to list every model from /v1/models, then pin one such as anthropic/claude-sonnet-5.5 when a task needs it.
Record your own results with the workload CSV and report template. These are blank templates, not published benchmark results.
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.
