Virtual poolant:free

ANT Free

Zero-cost routing across every free model in the pool.

How this pool routes

ant:free routes only to models that cost nothing, drawing on the free-model pool and its own fallback chain across providers. Throughput is bounded by upstream free-tier rate limits rather than your balance.
