Language pricing page ↗Creator and first-party host of the Grok model family. Standard per-1M-token input/output pricing published at x.ai/api.
1 current-gen
Video pricing page ↗xAI's own first-party API. Grok Imagine offers both video and image generation; video is billed per second of output at a flat rate — no resolution-based pricing tiers on the current docs.x.ai model pages.
1 current-gen
Audio pricing page ↗xAI (a subsidiary of SpaceX as of April 2026) offers the Grok Voice Think Fast line — speech-to-speech conversational voice models accessible via the xAI API's Voice API, billed per minute of audio. Pay-per-use, no subscription required. Distinct from xAI's text-generation (Grok 4.5) and image/video (Grok Imagine) product lines, which are out of scope for this audio-only registry.

8 models tracked across all verticals. Earliest release 2025-02, most recent 2026-09.
Derived from Modelglass's per-vertical provider registries — image/llm/video/audio's registry/providers/*.yaml records, plus science/coding/agentic/gdpval's benchmark registries, where a provider is identified by the prefix before "/" in each model's model_id rather than a registry record of its own. Where the same company uses a different provider slug or model_id prefix across verticals (e.g. Google DeepMind vs. Google Cloud, or Qwen's "alibaba" model_id prefix in the coding registry vs. its "qwen" provider slug elsewhere), coverage is merged onto a single profile per an explicit, human-reviewed alias list (registry/provider-aliases.yaml) — everything else reflects exact-slug or exact-prefix matches only.
