Flash for volume, Pro for hard tasks

V4.1 Flash is the low-cost option for chat, extraction and agents with many calls. V4 Pro handles harder reasoning and long outputs at a higher rate. Both accept the same request shape, so switching is a model ID change.

Verified parameters

Tokely tested both models with streaming usage, function tools, JSON mode, temperature, top_p, stop sequences and reasoning effort. V4.1 Flash also accepts inline images; V4 Pro is text-only on Tokely.

Caching

Repeated prefixes are billed at the cache-read rate when the supplier reports a cache hit, and cached tokens are not billed again as regular input.

One key for every model

Every model on this page is available through one OpenAI-compatible endpoint and one balance, with routing modes, bounded fallback, spending limits and request logs.
