Model pricing

X6.AI bills by token usage. OpenAPI GET /v1/models returns model metadata only — not sell prices. Use the developer console → Models marketplace as the source of truth.

Where to see prices

1. Sign in to the Developer Console.
2. Open Models.
3. Open a model’s detail page and check Pricing.

Pricing tiers (current model)

Model detail pages show four token rates (usually $/1M tokens; missing tiers fall back to the input rate):

Tier	Meaning
Input	New input tokens (not from cache)
Cache read	Input tokens served from Prompt Cache (usually cheaper)
Cache write	Tokens written into cache on first use. Some models split short TTL / long TTL write rates (e.g. Anthropic 5m / 1h; OpenAI-style windows such as 30m / 12h)
Output	Completion tokens

Optional dimension:

Dimension	Meaning
Long context	When context exceeds the model’s configured threshold, input (and cache read/write that follow the input path) and/or output are multiplied by the rates shown on the detail page

Follow what the marketplace displays. If cache read/write rates are unset, those tokens still bill at the input rate (not free).

OpenAPI vs billing

Scenario	Description
List models	GET /v1/models — no prices
Actual charges	After a successful POST /v1/chat/completions, POST /v1/messages, or POST /v1/responses, X6.AI bills from token usage in the response (including cache read/write) at marketplace rates; long-context multipliers apply when matched

See Chat Completions — usage & Prompt Cache billing for the simplified formula. For per-request reconciliation, use response header X-Request-Id (same value as X-SNX-Trace-ID) with GET /v1/billing/requests/{request_id}.
