Claude vs GPT Pricing: Full Breakdown
Is Claude cheaper than GPT? It depends on the model, the tier, and whether your workload is input-heavy or output-heavy. This page compares every Claude and GPT model side by side, with real dollar examples so you can pick the right one.
Head-to-Head: All Claude vs GPT Models
Here is every current Claude and GPT model with its per-token pricing and context window. All prices are per 1 million tokens.
| Model | Provider | Input / 1M | Output / 1M | Context |
|---|---|---|---|---|
| Anthropic (Claude) | ||||
| Claude Fable 5 | Anthropic | $10 | $50 | 1M |
| Claude Opus 4.8 | Anthropic | $5 | $25 | 1M |
| Claude Sonnet 5 | Anthropic | $2 | $10 | 1M |
| Claude Haiku 4.5 | Anthropic | $1 | $5 | 200K |
| OpenAI (GPT) | ||||
| GPT-5.6 Sol | OpenAI | $5 | $30 | 1.05M |
| GPT-5.5 Pro | OpenAI | $30 | $180 | 400K |
| GPT-5.6 Terra | OpenAI | $2.50 | $15 | 1.05M |
| GPT-5.5 | OpenAI | $5 | $30 | 400K |
| GPT-5.6 Luna | OpenAI | $1 | $6 | 1.05M |
Price Per Word and Per Page
Token pricing can feel abstract. Here is what each model costs when you think in words and pages instead. One token is roughly 0.75 words, so 1 million tokens is about 750,000 words. A standard page is ~500 words (~667 tokens).
| Model | Input / word | Output / word | Input / page | Output / page |
|---|---|---|---|---|
| Claude Fable 5 | $0.000013 | $0.000067 | $0.007 | $0.03 |
| Claude Opus 4.8 | $0.000007 | $0.000033 | $0.003 | $0.02 |

Tier-by-Tier Comparison
The fairest comparison matches models of the same tier. Here is how each Claude model stacks up against its GPT counterpart.
Frontier: Claude Fable 5 vs GPT-5.6 Sol
Flagship: Claude Opus 4.8 vs GPT-5.6 Terra
Input-Heavy vs Output-Heavy Workloads
Which provider wins depends on what you are doing. Input-heavy workloads (reading documents, analyzing code, processing data) are dominated by input token costs. Output-heavy workloads (writing articles, generating code, producing reports) are dominated by output costs.
Input-Heavy (Reading)
The cheapest Claude model for input is Claude Haiku 4.5 at $1 / 1M. The cheapest GPT model for input is GPT-5.6 Luna at $1 / 1M.
Same input price at the budget tier
Output-Heavy (Writing)
The cheapest Claude model for output is Claude Haiku 4.5 at $5 / 1M. The cheapest GPT model for output is GPT-5.6 Luna at $6 / 1M.
Claude wins on output: 1.2x cheaper
Real Dollar Examples
Abstract per-token prices are hard to reason about. Here are three concrete scenarios with real costs on every Claude and GPT model.
Summarizing 500 pages
333,500 input tokens (500 pages at ~667 tokens/page)

The Bottom Line
At the frontier tier, Claude Fable 5 is significantly cheaper than GPT-5.5 Pro on both input and output, while also offering a larger context window (1M vs 400K tokens).
At the flagship tier, Claude Opus 4.8 and GPT-5.5 share the same input price ($5 / 1M), but Claude Opus 4.8 is cheaper on output ($25vs $15) and comes with a much larger context window.
For budget workloads, Claude Haiku 4.5 at $1 / $5 is the cheapest Claude option. OpenAI does not currently offer a budget model in the GPT family, so Claude has the advantage for cost-conscious projects.
Short version: if you want the lowest price and the biggest context window, Claude wins across the board. GPT-5.5 competes at the flagship tier on input price but costs more for output.
