How do I use Grok 4.3 in Cline or OpenCode without per-token billing?
Set the model to x-ai/grok-4.3 in Cline, OpenCode or Aider with a Standard Compute key: Grok 4.3 is part of every plan from $19 a month, no xAI account needed, and new requests return HTTP 402 when the plan's compute budget reaches 100%. xAI's newer Grok 4.5, 4.6 and 4.7 are not served.

What it costs
| Per 1M tokens | Prompt under 200K | Prompt 200K or more |
|---|---|---|
| Input | $1.25 | $2.50 |
| Cached input | $0.20 | $0.40 |
| Output | $2.50 | $5.00 |
xAI API rates. The higher column applies once a prompt reaches 200K tokens. Source: xAI models and pricing, checked October 13, 2026.
With output at twice the input price, Grok 4.3 suits jobs that write a lot, such as long summaries or generated files. For hard agent steps, select a stronger model next to it.
What works differently here
- Grok 4.3 trails current coding models: its Artificial Analysis rating is 25, below the median of 27 for its price group, and the AA page points readers to xAI's newer release, which this gateway does not carry yet.
- Prompts of 200K tokens or more pay double on xAI's list, and long coding sessions get there.
