Top 5 Most Expensive Deep Reasoning Models in the Market BILINGUAL COST ANALYSIS REPORT • 双语费用深度解析报告

Rank

Model Name

Input $/M

Output $/M

Position OpenAI o1-pro $150.00 $600.00

Enterprise exclusive; utilizes 10x the compute of regular o1; not available for public retail. o1 $15.00 $60.00

The absolute ceiling of commercially purchasable reasoning models on the open market. Claude Opus 4 (extended thinking) $15.00 $75.00 Anthropic 推理旗舰，thinking tokens 采取

Anthropic’s reasoning flagship; internal thinking tokens are fully metered and billed. Grok-3 (DeepSearch) ~$5.00-10.00 $30.00-50.00

xAI’s flagship; generates extremely long reasoning chains under DeepSearch mode. Gemini 2.5 Pro (thinking) $3.75 $15.00

64K tokens。 Google’s premier reasoning model; supports an internal thinking window of up to 64K tokens.

But There Is a Critical Pitfall Market Analysis: Deep Reasoning Model Costs | 市场分析：深度推理模型成本

The rates listed above apply only to visible output tokens. The real budget killer of deep reasoning models is the thinking tokens—the vast volume of internal dialogue and self-correction the model generates before providing the final answer.

Example: Real o1-pro Billing Breakdown Your Input Query: 1,000 tokens Internal Thinking: 50,000 tokens ← Charged at output rate! Final Visible Res: 5,000 tokens ────────────────────────────────────────── Your Total Bill = 1K × $150/M + 55K × $600/M = $0.15 + $33.00 = $33.15 (True cost of a single query)

Thinking tokens are typically 5 to 100 times your visible output. Deep reasoning models are not just costly due to their base rates, but because you are forced to fund their massive internal monologue.

If You Truly Don’t Care About Money Market Analysis: Deep Reasoning Model Costs | 市场分析：深度推理模型成本

o1-pro remains the undisputed sovereign of costs. Its staggering $600/M output rate makes it 8 to 10 times more expensive than its closest rivals. However, it is kept away from the general public, reserved strictly for OpenAI’s premium enterprise clients. Consequently, the most expensive reasoning models genuinely accessible on the open commercial market are Claude Opus 4 extended ($75/M) and o1 ($60/M). Never underestimate their operating expenses: a moderately complex reasoning task that burns through 100K thinking tokens and 10K visible output tokens can easily drive the cost of a single query past $80 USD.
