vs

Grok Build 0.1 vs Grok 4.7

Two xAI models, compared on listed price, real workload cost, context and capabilities.

The short answer

  • Grok Build 0.1 lists lower input and output prices.
  • Grok 4.7 offers the larger context window.
  • Grok Build 0.1 reads cached input for less ($0.2/M against Grok 4.7's $0.5/M), which decides the bill for agents that resend long context.

At listed rates. Token counts are typical sizes, not measurements.

Grok Build 0.1 pricing notes

  • Rates double once a request reaches 200K input tokens ($2 / $4, cached $0.40) and apply to the whole request; the listed price is the sub-200K rate.

Grok 4.7 pricing notes

  • Once a prompt reaches 200K tokens, every rate doubles for the whole request ($4 input, $12 output, $1 cached); the listed price is the sub-200K rate.

When to pick which

Grok Build 0.1

xAI's coding model for agentic coding and tool calling, and the model that powers Grok Build. It bills half Grok 4.7's input rate and a third of its output rate, on a 256K window instead of 500K.

Pick it if

  • you run agentic coding, debugging or tool-calling loops on a budget
  • you want xAI coding at a third of Grok 4.7's output rate
  • your prompts repeat, so cached input bills at a fifth of input

Skip it if

  • you need more than 256K tokens of context; Grok 4.7 offers 500K

Grok 4.7

xAI's model for coding and knowledge work, launched September 2026 as the successor to Grok 4.6 at the same price and speed. It takes text and images, and reasoning is always on.

Pick it if

  • you want xAI's top model for coding and multi-hour terminal tasks
  • your prompts repeat: cached input bills at a quarter of the input rate
  • you need text and image input in one 500K window

Skip it if

  • Grok Build 0.1 fits your work: half the input, a third the output price
  • you need a non-reasoning mode: reasoning on Grok 4.7 cannot be disabled

FAQ

Which is cheaper, Grok Build 0.1 or Grok 4.7?

Grok Build 0.1 lists lower input and output prices. On a coding-agent session (2M tokens in, 60,000 out) Grok Build 0.1 costs $2.12 and Grok 4.7 $4.36.

Which has the larger context window?

Grok 4.7 offers the larger context window. Grok Build 0.1: 256k tokens; Grok 4.7: 500k tokens.

Can I switch between Grok Build 0.1 and Grok 4.7 mid-task?

Yes. In an Octomind session, /model octohub:grok-build-0.1 and /model octohub:grok-4.7 switch models without losing the conversation, so you can draft on one and review on the other.
