Claude vs Grok
Two product families, side by side — subscriptions, API pricing, and which one to reach for.
The short answer
Claude leads on raw capability — its strongest model, Claude Fable 5, posts the higher combined coding and reasoning score in this comparison. Claude is the cheaper way in: Claude Haiku 4.5 blends to $2.20 per million tokens, which is what matters once you are running volume rather than evaluating. Claude offers the wider context window at 1M tokens. Most teams end up using both — one for the hard problems, one for everything else.
Claude
Anthropic's assistant, favoured for long-document work, writing quality, and agentic coding. The API family runs from an always-thinking frontier model down to a fast extraction tier, with a 1M context window across the current generation.

Grok
xAI's assistant, bundled with X Premium. The API's headline feature is output-token pricing well below its capability peers, which makes it unusually cheap for generation-heavy workloads.

Subscriptions
What Claude and Grok charge a person per month.
Claude sells a consumer subscription; Grok is used mainly through its API or bundled elsewhere, so there is no like-for-like monthly price to compare. If you want a chat product you pay for monthly, that decision is already made for you.

API pricing, tier by tier
Claude and Grok line-ups matched by capability tier.
| Tier | Claude | Grok |
|---|---|---|
| Flagship | Claude Fable 5$10.00 / $50.00 per 1M in / out | — |
| Mid-range | Claude Sonnet 5$3.00 / $15.00 per 1M in / out | Grok 4.5$2.00 / $6.00 per 1M in / out |
| Budget | Claude Haiku 4.5$1.00 / $5.00 per 1M in / out | — |
At 10M + 2M tokens a month — a realistic mid-size production workload — the cheapest option from Claude (Claude Haiku 4.5) runs about $20.00, against roughly $32.00 for Grok's Grok 4.5. Run your own numbers on the calculator before committing: the mix of input to output tokens moves this more than the headline price does.
