OpenAI, Anthropic slash LLM API prices amid intense competition

By PulseAugur Editorial · [1 sources] ·

OpenAI has significantly reduced its API pricing for Luna (GPT-5.6) by 80%, and Anthropic has also halved the price of Opus 5. This intense price competition in the LLM API market benefits developers by lowering costs. However, the author warns that these price cuts can mask fraudulent practices where third-party providers bill for premium models but serve cheaper ones, as the relative profit margin can still increase. To combat this, the author introduces an open-source tool, llm-honesty-probe, which uses behavioral fingerprinting to verify if an API endpoint is serving the model it claims to. AI

IMPACT Developers can use new verification tools to ensure they receive the LLM services they pay for amidst API price wars.
