Anthropic Claude API Pricing (June 2026)

Anthropic's Claude models are known for strong reasoning, coding, and safety. In June 2026, Claude Fable 5 becomes the new generally available top tier, with limited-preview Claude Mythos 5 above the public lineup for approved Project Glasswing customers.

Claude pricing is generally higher than OpenAI across comparable tiers, but Anthropic compensates with 1M-token context on Fable 5, Mythos 5, Opus 4.8, and Sonnet 4.6, strong coding performance, and aggressive prompt-caching discounts.

Claude Fable 5 and Mythos 5 (Latest Frontier Tier)

• Claude Fable 5 ($10.00 input / $50.00 output) - Anthropic's most capable widely released model for the hardest reasoning, long-horizon agentic work, coding, and vision tasks. It supports 1M context and up to 128K output. Read the Fable 5 pricing breakdown →
• Claude Mythos 5 ($10.00 input / $50.00 output) - Limited Project Glasswing availability for approved customers. Anthropic describes it as the same capability class as Fable 5 with broader safeguards lifted for specific trusted use cases.
• Claude Opus 4.8 ($5.00 input / $25.00 output) - Cheaper premium Claude option for complex reasoning, agentic coding, and high-autonomy work. It remains half the standard API price of Fable 5.
• Claude Sonnet 4.6 ($3.00 input / $15.00 output) - Best price-to-performance ratio in the Claude lineup. 1M context, excellent for everyday coding and production workflows.

Claude Haiku (Budget Tier)

Haiku models provide the best value in Anthropic's lineup:

• Claude Haiku 4.5 ($1.00 input / $5.00 output) — Fast, capable, good for production workloads
• Claude Haiku 3.5 ($0.80 input / $4.00 output) — Popular mid-tier option, strong quality-to-cost ratio
• Claude Haiku 3 ($0.25 input / $1.25 output) — Anthropic's cheapest model. Great for classification, extraction, and high-volume tasks.

Prompt Caching Discounts

Anthropic's prompt caching is one of the most aggressive in the industry. Cache reads cost only 10% of base input price:

• Claude Fable 5 and Mythos 5: $1.00/M cached (vs $10.00 standard) - 90% savings
• Claude Opus 4.8: $0.50/M cached (vs $5.00 standard) - 90% savings
• Claude Sonnet 4.6: $0.30/M cached (vs $3.00 standard) - 90% savings

Batch API offers an additional 50% discount, making Claude Haiku 3 batch pricing just $0.125/M input — competitive with the cheapest models on the market.

Legacy Models: Still Available, Often Expensive

Earlier Claude models like Opus 4.1 and Opus 4 remain available at $15.00/M input, which is more expensive than the newer Fable 5 tier. Opus 4.7 and 4.6 are now previous-generation. There's rarely a good reason to use legacy models unless you have specific compatibility requirements.

How Claude Compares

Claude Fable 5 ($10.00 input) is the new premium Claude tier. It is 2x Opus 4.8 and 4x GPT-5.4 input pricing, so it should be reserved for work where the extra capability materially changes the result. Opus 4.8 still matches GPT-5.5 input pricing and undercuts GPT-5.5 output pricing ($25 vs $30).

The real value proposition for Claude is context window size, coding quality, frontier reasoning, and cache economics. Many developers will route only the hardest jobs to Fable 5 while keeping Sonnet 4.6 or Opus 4.8 for bulk work.
