Quick Decision

Verdict

Hy4 has the lower input price; Hy4 has the lower output price; Hy4 offers the larger context window. For the 1M input plus 500K output sample, Hy4 is cheaper for the standard workload.

For a 1M input token plus 500K output token workload, the estimated API cost is $1.04 for Hy4 and $5 for Fugu Max.

Best Fit

Choose Hy4 when you care most about lower input-token price, lower output-token price, and larger context window.

Choose Fugu Max when its provider, model quality, latency, or availability is more important than the numeric price/context winner.
