AI API changes, without the guesswork.

model retirementSearch repositories and deployment configuration for claude-opus-4-1-20250805. The official source lists claude-opus-4-8 as a replacement identifier. Test the migration against current provider documentation before production.

model shutdownChange the model ID to gemini-embedding-2 and validate vector dimensions, storage, and retrieval quality in a staging index before cutover.

model shutdownMove to gemini-3.1-flash-image and test request shape, output handling, latency, image quality, and safety behavior before the deadline.

api sunsetInventory Assistants and Threads SDK usage, map it to Responses and Conversations, migrate stored state, and run end-to-end tool and conversation tests before August 26.

model shutdownReplace the retired model ID with an official recommended model, update the API request shape where required, and regression-test prompts and outputs.

breaking behaviorStop sending temperature, top_p, and top_k for affected models. Express tone, variability, and formatting requirements in the system prompt instead.

breaking behaviorRemove manual thinking budgets and non-default sampling parameters, rely on adaptive thinking, and use Anthropic's token-counting API to recalibrate limits and cost controls.

parameter deprecationStrip temperature, top_p, and top_k from Gemini requests and encode response constraints in a clear system instruction.
