Your model ID is the shortest-lived dependency in your stack and odds are it doesn’t have a maintenance schedule. On June 15, 2026, claude-sonnet-4-20250514 and claude-opus-4-20250514 stopped answering requests. Anthropic had posted the notice 62 days earlier.

Looking at the trace of a long-running coding or ops agent, you will see the same pattern. A significant share of the steps are mechanical: construct a tool call, check the output format, retry on a transient error, summarise a log, classify a result. None of that requires frontier reasoning. None of it requires a […]

Picking an inference vendor used to be a short conversation. You wanted Llama behind an HTTP endpoint, three companies served it, and their prices sat close enough that the decision came down to whoever had capacity. The market has since split into a dozen serious operators running truly different businesses. The best open source LLM […]
