Grok and Claude pulled in opposite directions in our run. Grok was the cheapest and the most concise, answering in a third of the cost and a third of the length. Claude was the fastest to respond and gave the fuller, more structured answer. Each won a different measure, so the right pick comes down to which measure you care about.

The run

The whole setup behind the numbers:

  • Prompt: one everyday question (below), with an “under 200 words” limit.
  • Models: Grok grok-4.7 and Claude claude-opus-5-5.
  • Settings: each model’s default, temperature 0.7, no system prompt, no extra context.
  • Keys: our own, calling each provider directly. One real run.

Prompt

A small bakery owner asks: “A customer wants to return a custom birthday cake they already picked up, saying it was ’too sweet.’ They’ve eaten half of it. How should I handle this professionally while protecting my small business?” Give practical, specific advice in under 200 words.

The result, side by side

Grok (grok-4.7)

  • Cost: $0.0035 (cheaper here)
  • Speed: 10.5 seconds
  • Length: 146 tokens (most concise)
  • Style: one tight paragraph

Claude (claude-opus-5-5)

  • Cost: $0.0094
  • Speed: 5.6 seconds (faster here)
  • Length: 450 tokens
  • Style: warm, structured, with a prevention checklist

The actual answers:

Grok (grok-4.7)
Acknowledge the complaint calmly and thank them. Once picked up and partly eaten, a subjective complaint like “too sweet” is not a defect and does not require a refund. State your policy clearly: no returns on custom items after pickup. Offer a small goodwill gesture only, such as 10 percent off a future order. Note the conversation and put the policy in writing at order and pickup.
Claude (claude-opus-5-5)
Stay calm and professional. Thank them and acknowledge the disappointment without admitting fault; sweetness is taste, not a defect. Hold your position on a full refund since half was eaten and custom items can’t be resold. Offer a goodwill gesture if you want to keep the customer, document everything, post a clear written policy with a signature, and reply to any bad review with brief, polite facts.

Both reach the same core advice. The measurable difference is which lever each pulled: Grok on cost and brevity, Claude on speed and depth.

Insight: When two models each win a different metric, averaging them into “which is better” throws away the useful information. The honest read is a mapping:

  • Tight budget or a brevity requirement points to the cheaper, shorter answer.
  • A latency-sensitive or detail-hungry job points to the faster, fuller one.

Run your own task and pick on the metric that actually binds you.

These results come from a specific run on 2026-11-02 on one defined task, using real models through a real pipeline. They show how each model performed on that task, not a general ranking of model quality, which depends entirely on your task and data. Run your own to see your numbers.
