By PulseAugur Editorial · [1 sources] ·

OpenAI is particularly affected, with 28 model IDs scheduled for shutdown on October 23rd, and others on October 31st. While Anthropic, Mistral, Groq, and Cohere did not announce new deprecations this month, users are advised to check their configurations for any affected model IDs and plan for replacements to avoid service disruptions.
