Pricing	usage	usage
Strengths	+ Half the per-token price of GPT-5.5 while staying in the frontier coding/professional tier + 1M-token context window with up to 128K output tokens + mini variant targeted at subagent and computer-use workloads for high-volume agent fleets	+ Higher retrieval quality than voyage-3 on demanding corpora + API-based; no embedding infrastructure to host
Tradeoffs	− OpenAI directs complex reasoning and coding to GPT-5.5 instead − Older knowledge cutoff (Aug 31, 2025) than GPT-5.5	− More expensive per token than voyage-3 − API-only; document text leaves your environment to be embedded
