goose session --provider oceantoken --model deepseek/deepseek-v4-flashWhat it costs
An agent resends a long prompt on every turn, so the cached input price matters as much as the input price. DeepSeek V4 Flash 0423 caches the repeated part of the prompt on its own: from the second turn of a task it is billed at the cached input price.

Frequently asked questions
Does DeepSeek V4 Flash 0423 work with goose’s tools?
Yes. It was tested on October 19, 2026 with goose CLI 1.54.0: writing and running a small program with its file and shell tools.
How much does DeepSeek V4 Flash 0423 cost in goose?
Every request goose makes is billed at the model’s price: $0.21 / $0.84 per 1M input / output tokens. The repeated part of a long prompt is billed at $0.006 per 1M cached input tokens. Each request’s charge is in the console under Logs.
Where do I put my OceanToken key?
Create a key in the OceanToken console and give it a credit limit: an agent sends many requests, and the limit caps what this key can spend. Keep it in an environment variable, never in a file in your repository.
