Cheapest viable option: GPT 5.6 Luna at $0.001260/call (59% less, 85/100 quality).
The most bounded question-answering shape: a short question against a fixed knowledge base, with a short answer. Because the knowledge base never changes between calls, cache reads apply to nearly the entire input, and the effective cost per answer falls well below the list rate. A fast-tier model is usually sufficient when the answers are already written.
For Grok Build 0.1 specifically, that means output tokens cost 2.0x more than input, at $2.00 vs $1.00 per MTok. At this use case’s 1,500/800 token split, output accounts for 52% of the $0.003100 per-call cost.
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $1.00 | 1,500 |
| Output | $2.00 | 800 |
Caching drops input cost from $1.00 to $0.20/MTok. For repeated system prompts, that saves $0.001200 per call.
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.

A typical faq bot call using Grok Build 0.1 costs about $0.003100 per call. This estimate uses 1,500 input tokens and 800 output tokens at standard rates. Standard rates are $1.00 per million input tokens and $2.00 per million output tokens.
Our benchmark data does not yet include a faq bot ranking for Grok Build 0.1. We recommend testing it against your own evaluation criteria before production usage.
The most affordable model for faq bot above 80/100 quality is GPT 5.6 Luna. It comes from GPT at $0.20 per million input tokens. Output costs $1.20 per million tokens with a quality score of 85/100. Switching from Grok Build 0.1 to GPT 5.6 Luna saves about 59% per API call.
Three strategies lower Grok Build 0.1 costs for this task type effectively. Prompt caching gives a 80% discount on input tokens when reusing system prompts. The batch API gives 50% off all tokens for asynchronous processing workloads. Prompt optimization reduces token counts through more concise instructions and context windows. Combining caching with batching brings your cost from $0.003100 to about $0.000310 per call.
Grok has 3 other models alongside Grok Build 0.1 today: Grok 4.6 at $2.00/$6.00 per million tokens (flagship), Grok 4.5 at $2.00/$6.00 per million tokens (flagship), Grok 4.3 at $1.25/$2.50 per million tokens (mid-tier). The right choice depends on whether your faq bot workload prioritizes quality, cost, or speed.
Grok Build 0.1 supports a context window of 256K tokens per API call. This sets the maximum combined length of your input prompt and generated response. For faq bot, typical calls use 1,500 input and 800 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
