Remember to switch to the corresponding group for the special price pure blood model. 5-minute cache hit rate is 99%, can RP lewd (with related processing, if it still doesn't work, it's too extreme). Quality is comparable to official C level, you can test it yourself on the evaluation site.

A small amount is being tested on the GCP channel. Prices are still being explored, and only minor changes are guaranteed. For other reverse channels, prefer using ant. CLI also has some volume available. For other questions or doubts, contact customer service.

Please test the actual model costs in the practice field to see the actual deduction. The model square may have too many digits not displayed and rounding issues, which should not be taken as the actual standard. For example, some models are 0.0015 displayed as 0.002 and 0.0001 displayed as 0.000. Why explain in such detail? Because I really have many models priced this way ()

Notes
- Health checks: Scope: the 72-hour chart and recent availability measure API connectivity only. Each bar summarizes one hour of checks. Targets: LMSpeed tries the configured health check URL and provider status URL first, then API endpoints derived from known API hosts and recent speed-test base URLs. A website host is considered only when it looks like an API endpoint. Probe steps: each candidate goes through DNS lookup, TCP connection, TLS handshake for HTTPS, and an HTTP HEAD request with redirects followed. Probing stops after the first reachable candidate. Reachable criteria: every required network step must succeed. An HTTP response below 500 is treated as reachable, including 401 because it confirms that an authenticated API endpoint responded, except for statuses classified as blocked. Blocked results: HTTP 403, 429, 521, 525, and 530, plus detected WAF or Cloudflare challenges, are shown as blocked and excluded from availability calculations because LMSpeed cannot determine whether the API itself is down. Model availability: when a dedicated test key is configured, LMSpeed sends an authenticated GET request to a derived /models endpoint and compares returned model IDs with this provider's listed models. These per-model results appear in Models & Pricing and are not included in the provider connectivity percentage. Timeouts: TCP connection, TLS handshake, HTTP connectivity, and model requests each use a 20-second timeout. A full run can take longer when several candidates are tried. Frequency: a background worker checks all providers every 5 minutes by default. The 72-hour chart combines those samples into hourly bars, and the schedule may be changed by the service operator. Limit: automated samples are not an SLA and do not guarantee account quota, every model, every region, or successful completion requests. Check the provider's own status page before making operational decisions.
