Standard reference rates only; batch, priority, regional or tool charges may differ.

Tasks to evaluate

Ticket classification, short summaries and context processing. Evaluate labeled samples and human handoff rates.

Limits and cost considerations

Long prompts use different pricing tiers. Complex open-ended tasks need separate evaluation; no independent benchmark is claimed.

Token estimates are available for reviewed text-model routes and cover uncached text input and output only. It excludes cache writes, tools, other modalities, time-of-use adjustments, retries and processing premiums. A rate tier is not a context limit. Missing prices stay unavailable rather than becoming zero. Selection uses the lowest input rate, not necessarily the lowest total task cost.

A small integration acceptance check

POSIX shell template for a channel offering Chat Completions. Set the account-provided base URL (normally including /v1) and API key in your terminal. Confirm this exact identifier is enabled. Running it makes a billable request; this page does not send it.

curl "$YOUJIE_BASE_URL/chat/completions" \
  -H "Authorization: Bearer $YOUJIE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"claude-haiku-5-5","messages":[{"role":"user","content":"Return a JSON object with the sum of 17 and 25 under the key total. No other text."}],"stream":false}'

Acceptance target: parse the final message as JSON and verify total equals 42. This is a known mathematical target, not a recorded model response. Also inspect HTTP status, response structure and actual usage. No tool calling or strict-schema feature is assumed.
