PrismML: Ternary Bonsai 2 27B

PrismML: Ternary Bonsai 2 27B is a large language model API from prism-ml, part of its Ternary Bonsai model family. At $0.075 per million input tokens and $0.500 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 7× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. A large 262K-token context window (≈393 pages of text) lets it take in whole books, large codebases, or lengthy transcripts in a single call. Beyond plain text it also accepts Image input, so it can be applied to multimodal tasks rather than text alone. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
