xAI (Grok)
External APIs
xAI serves Grok 4.7 at $2 and $6 per million. The editor keeps thirty days for abuse auditing, without training on inputs.
Key points : Grok 4.7 · Thirty-day retention · No training without permission.
Models served : the range opens with Grok 4.7, released on 21 September 2026, at $2 input and $6 output per million, with configurable reasoning. Its 500,000-token context is the only one on the frontier line to stay below a million. A voice interface and an image interface round out the offering.
Where the data goes
The editor writes that it never trains on API inputs or outputs without explicit permission. Requests and responses are kept encrypted at rest for thirty days, to audit suspected misuse, then automatically deleted. A zero data retention option exists for demanding teams.
Retention and training
The thirty-day window is the only published duration, and it applies by default. The editor offers to attribute violations to an opaque identifier supplied by the customer, rather than to the whole key, which avoids passing an email address or a name.
When to use it from a sovereign platform
The written commitment not to train, together with a stated retention period, is more precise than at several competitors. The 500,000-token context remains the shortest on the frontier line, which matters for an agent reading long repositories.
