Doubao Seed models provide a low-cost entry point for general chat, with lighter and turbo tiers that scale down to small budgets.
When to use it
At $0.92 per 1M input tokens it sits above the catalogue median of $0.69 — a capability-first choice. Best for coding agents and repository-scale edits. Every model here is reachable with the same API key, so trialling it against a stronger sibling costs one line of code.
