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
Claude Sonnet 4.6 from Anthropic offers a 1M-token context window and is well-suited to strong tool calling, multi-step reasoning, coding, long-context work. Pricing is $3 in / $15 out per 1M, billed per token through the provider API.
Watch for the trade-offs: output pricing is on the higher side; weights are closed, so you cannot self-host.
