Why it's trending
The launch of Claude Opus 5 is trending because it offers near-flagship intelligence at significantly lower cost, addressing enterprise demand for value. The simultaneous integration with GitHub Copilot also expands its reach to developers.
Anthropic on Friday announced Claude Opus 5, its latest AI model, which the company says delivers frontier-level performance on coding and knowledge work at half the price of its flagship Claude Fable 5. According to a blog post, Opus 5 is 'thoughtful and proactive' and designed for everyday use, becoming the default model on Claude Max and the strongest option on Claude Pro.
The model surpasses all other models on the Frontier-Bench v0.1 and GDPval-AA evaluations, according to Anthropic. However, on cybersecurity tasks it remains behind the specialized Claude Mythos 5, which the company previously said excels at discovering vulnerabilities. Pricing is set at $5 per million input tokens and $25 per million output tokens, as reported by CNBC, making it cheaper than Fable 5.
Anthropic head of product management Dianne Penn told CNBC that enterprises are 'looking for value,' a factor driving the model's development. The launch comes amid broader industry pressure to reduce AI costs, with competitors including OpenAI, Microsoft, and Google offering cheaper alternatives. Anthropic also faces regulatory scrutiny; it briefly disabled access to Mythos 5 and Fable 5 in June to comply with an export control directive.
GitHub Copilot has integrated Claude Opus 5 for complex, long-running coding tasks. In early testing, the model showed strong performance on agentic workflows like autonomous code changes and regression verification, per a GitHub changelog. The model includes enhanced safeguards for high-harm cyber content. Availability is gradual for Copilot Pro+, Max, Business, and Enterprise users.
