ChatGPT vs Claude: Full Pricing Comparison (2026)

A detailed breakdown of OpenAI GPT-5.4 vs Anthropic Claude Opus 4.6 pricing. Compare input, output, and cached token costs to find the best value for your use case.

Choosing between ChatGPT (OpenAI) and Claude (Anthropic) in 2026 comes down to what you’re building and how much you’re willing to spend. Both providers have released major new models this year, and the pricing landscape has shifted significantly.

Here’s the full breakdown.

Quick Comparison: GPT-5.4 vs Claude Opus 4.6

GPT-5.4Claude Opus 4.6
Input$2.50 / 1M tokens$5.00 / 1M tokens
Cached Input$0.25 / 1M tokens$0.50 / 1M tokens
Output$15.00 / 1M tokens$25.00 / 1M tokens
Context Window270K tokens1M tokens
Max Output32K tokens128K tokens

Bottom line: GPT-5.4 is 50% cheaper on input and 40% cheaper on output than Claude Opus 4.6. But Claude gives you nearly 4x the context window and 4x the max output length.

Mid-Tier: GPT-5.4 mini vs Claude Sonnet 4.6

For most production workloads, you’re probably looking at the mid-tier models:

GPT-5.4 miniClaude Sonnet 4.6
Input$0.75 / 1M tokens$3.00 / 1M tokens
Cached Input$0.075 / 1M tokens$0.30 / 1M tokens
Output$4.50 / 1M tokens$15.00 / 1M tokens
Context Window270K tokens1M tokens

GPT-5.4 mini is 4x cheaper on input and 3.3x cheaper on output than Claude Sonnet 4.6. This is a massive cost difference for high-volume applications.

However, Claude Sonnet 4.6 is widely regarded as the strongest coding model available, and its 1M-token context window is a genuine advantage for large codebases.

Budget Tier: GPT-5.4 nano vs Claude Haiku 4.5

GPT-5.4 nanoClaude Haiku 4.5
Input$0.20 / 1M tokens$1.00 / 1M tokens
Cached Input$0.02 / 1M tokens$0.10 / 1M tokens
Output$1.25 / 1M tokens$5.00 / 1M tokens
Context Window270K tokens200K tokens

GPT-5.4 nano is 5x cheaper than Claude Haiku 4.5. For simple, high-volume tasks like classification, extraction, or routing, this cost difference is significant.

When to Choose OpenAI (GPT-5.4)

  • Cost-sensitive production workloads — significantly cheaper across all tiers
  • Batch processing — 50% discount via Batch API
  • Multimodal (images, audio, realtime) — broader modality support
  • High-volume, simple tasks — nano tier is extremely affordable

When to Choose Anthropic (Claude)

  • Coding and development — Claude Sonnet 4.6 excels at code generation and review
  • Long-context tasks — 1M-token window vs 270K
  • Agent workflows — Claude’s extended thinking and agentic capabilities are industry-leading
  • Long-form output — 128K max output vs 32K

The Hidden Cost: Cached Input Pricing

Both providers offer cached input pricing, but the savings differ:

  • OpenAI: 90% discount (e.g., $2.50 → $0.25)
  • Anthropic: 90% discount (e.g., $5.00 → $0.50)

If your application reuses the same system prompt or context across requests, cached pricing dramatically reduces your costs. Factor this into your decision.

Real-World Cost Example

Let’s say you’re processing 10 million input tokens and 2 million output tokens per day:

GPT-5.4 mini:

  • Input: 10M × $0.75/1M = $7.50
  • Output: 2M × $4.50/1M = $9.00
  • Daily total: $16.50 ($495/month)

Claude Sonnet 4.6:

  • Input: 10M × $3.00/1M = $30.00
  • Output: 2M × $15.00/1M = $30.00
  • Daily total: $60.00 ($1,800/month)

That’s a $1,305/month difference — or $15,660/year.

Our Recommendation

For most teams in 2026:

  1. Use GPT-5.4 mini as your default — best price-to-performance ratio
  2. Use Claude Sonnet 4.6 for coding tasks — worth the premium for code quality
  3. Use GPT-5.4 nano for high-volume simple tasks — unbeatable at $0.20/1M input
  4. Use Claude Opus 4.6 only when you need the best — the premium is steep but justified for complex reasoning
