Call grok-4.6 through RouterPlex's OpenAI-compatible API — vendor list price, 0% markup, billed per token from a prepaid balance. No subscription required.
On cost it sits in the mid-range band of the catalog: the 23rd cheapest of 39 comparable text models, at about $0.26 per 100K-in / 10K-out agent turn — cheaper than 14 others on the same key. Its 500K context window ranks 25th of 39.
Base rate applies below 200K prompt tokens. Prompts at or above 200K are billed at $4 input / $12 output per 1M tokens. Cached prompt tokens are billed at xAI's published $0.50 per 1M rate ($1 in the long-context tier).
These examples apply the published input and output token rates directly. Actual cost depends on the tokens your client sends and the model returns.
10K input + 1K output tokens
100K input + 10K output tokens
Past 200K tokens in a single request, Grok 4.6 bills at $4.00 per 1M input and $12.00 per 1M output — 2.0× more on input than the standard rate. The threshold applies per request, not per conversation.
Every model below runs through the same endpoint and the same API key, so moving between them is a one-line model ID change. Costs are for the same 100K-in / 10K-out turn.
Quality is a separate question from price — see Grok 4.6 benchmark results before optimising on cost alone. Grok 4.6 reads images; for generating them see GPT Image 2 pricing.
