667 requests a month at 1,000 input and 500 output tokens each, about 1M tokens. The recommender uses the same assumption when you don't give your own usage.

Our take
GPT-5.4 Nano from OpenAI offers a 400K-token context window and is well-suited to long-context work. Pricing is $0.2 in / $1.25 out per 1M, billed per token through the provider API.
Watch for the trade-offs: weights are closed, so you cannot self-host.
