A ChatGPT Pro user reported encountering "Thinking failed" and HTTP 413 errors while using the chat for large-scale code review and planning, which typically indicates exceeding the max context length. The user noted that chats previously lasted nearly a month, but a new session hit the limit in just 3 days, suspecting a recent, unannounced change to context restrictions.
