Anthropic has slashed prices for its flagship AI model by a dramatic 67%, positioning Claude Opus 4.5 as a more accessible option for businesses and developers. The new pricing structure reduces input token costs from $15 to $5 per million tokens and output tokens from $75 to $25 per million.
Opus 4.5 now accessible to all with 67% price cut—revolutionary AI power at mainstream cost points.
This significant price reduction transforms Claude Opus from an expensive boutique solution into a mainstream enterprise tool that competes directly with offerings from OpenAI and Google.
The pricing adjustment brings Anthropic closer to market standards while maintaining its premium positioning. For comparison, OpenAI’s GPT-5.1 charges $1.25 for input and $10 for output per million tokens, while Google’s Gemini 3 Pro costs between $2-$4 per million input tokens. Claude Sonnet 4.5, Anthropic’s mid-tier offering, now costs $3/$15 per million tokens.
You’ll see substantial cost savings at scale with this new pricing. For example:
- Processing 50M input tokens and 20M output tokens now costs $750 instead of $2,250
- Running 100M input and 50M output tokens costs $1,750, down from $5,250
This price drop directly impacts enterprise adoption by making advanced AI reasoning economically viable.
Businesses can now utilize Opus 4.5’s extensive 200,000-token context window without prohibitive costs. Long-form outputs and complex reasoning chains become financially feasible for everyday use cases. The new pricing makes it an ideal solution for integrating with iPaaS systems, enabling real-time data synchronization across enterprise applications.
The model delivers impressive performance metrics, outperforming human candidates in engineering tests and showing superior thinking capabilities compared to Sonnet 4.5. Opus 4.5 scored an impressive 80.9% on the Software Engineering Benchmark Verified, outperforming both GPT-5.1-Codex-Max and Gemini 3 Pro.
When considering performance-per-dollar ratios, Opus 4.5 now represents one of the best values among frontier models in 2025.
This strategic pricing shift effectively democratizes access to high-end AI capabilities, removing financial barriers for mainstream development teams.
By making its most advanced model more accessible, Anthropic aims to accelerate adoption across industries while supporting its projected revenue growth to $10 billion in 2025.
The unified pricing in Anthropic’s Basic plan at $5.75 further simplifies the decision-making process for potential customers evaluating enterprise AI solutions.
Developers can optimize costs even further by implementing prompt caching techniques that can reduce input token expenses by up to 90% when reusing static content.
