How much does prompt caching change the deepseek-v4-pro vs gpt-6-sol gap?

Can TokenZero route gpt-6-sol traffic to deepseek-v4-pro safely?
Not automatically: cascade routing stays inside one provider so the request shape, tools and keys are unchanged. Cross-provider moves happen only on failover when you name the fallback model and key. Use the calculator to price a manual migration of the workload.
Is deepseek-v4-pro or gpt-6-sol being retired?
deepseek-v4-pro: active, no retirement announced. gpt-6-sol: active, no retirement announced. TokenZero audits flag retired ids and the gateway warns in X-TokenZero-Warning with the provider's replacement.
