theoldllm-api-pro provides API access to a wide range of AI models from various providers. Key features include:

Model Support: Access to models like GPT series (GPT-3.5 Turbo, GPT-4, GPT-4o, GPT-5), Claude series (Claude 3 Haiku, Claude 3.5 Sonnet), Gemini series (Gemini 2.0 Flash, Gemini 3 Pro), DeepSeek series (DeepSeek V3, DeepSeek R1), Llama series (Llama 3.1 8b), and many others including Mistral, Qwen, GLM, and custom models.
Capabilities: Supports text-based interactions with features like chain-of-thought reasoning (via Gemini-3/Claude-Thinking), file attachments (converted to text), and fingerprint simulation (Chrome 143).
Limitations: Does not support image processing or streaming output due to upstream restrictions. Some model IDs may display incorrectly (e.g., gemini-claude- prefixes actually refer to Claude models).
Use Cases: Suitable for developers and applications requiring multi-model AI integration without direct provider accounts, leveraging a single API endpoint for diverse model access.

This service routes requests through an upstream public site (https://theoldllm.vercel.app/) and uses a hybrid routing engine (Onyx Hybrid) for persona/proxy management.

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 5-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.

Domain Rating data is sourced from Ahrefs. It is a 0–100 backlink-based domain strength signal and does not measure API speed or reliability.

Announcements and FAQ are read from this provider's NewAPI status snapshot when available. LMSpeed stores the original content and optional English translations from the provider status source, then shows the localized fields on this page.
