Choose the experience you need. Harness plans are for coding in your terminal. API credit packs are for calling models from your own apps and scripts through Concurred. Email our team after purchase and we’ll provide your API key.
The discounts work differently. Harness plans renew monthly; the promotional credit amounts apply to your first month only. API packs are one-time purchases with no renewal. All API packs expire on 20 October 2026, regardless of purchase date. The crossed-out amounts show credit value, not a future subscription price.
The harness itself is free and open source under the MIT license. These offers pay for model usage. October Desktop plans are listed separately on the pricing page.
