What is changing across AI model APIs?
Budget migration work for each OpenAI shutdown, even where OpenAI names a replacement. The Evals platform and Agent Builder close on November 30, 2026, and older GPT-5 snapshots retire on December 11.
Pick where to buy GPT-6 on features, data processor, and quotas, because OpenAI and Azure Global Standard list the same prices. Amazon Bedrock drops several Responses API tools, including remote MCP servers and hosted file search.
Compare model APIs on cost per completed task. Anthropic and OpenAI now list the same prices at matching tiers, so cache hit rate, batch share, and tokens per task decide the bill.
