How this offer works

Both options cover model usage. Choose from all frontier models, including Fable 5.1 and Astra 6, with 500+ models to choose from.

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. Use promotional credits within 30 days; unused credits expire. 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.
