Why it matters: Anthropic is offering near-flagship capability at mid-tier pricing — Sonnet 5 approaches Opus 4.8 performance and is "cheap until August," per The New Stack. For developers building agentic applications, this lowers the cost of running autonomous workflows and intensifies price competition with OpenAI and other frontier-model rivals.
