Deep dive
The capability footprint differs most on structured outputs: Claude Instant 1.2. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Instant 1.2 lists $0.8/1M input and $2.4/1M output tokens, while ELYZA Japanese Llama 2 7B lists $0.2/1M input and $0.2/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts ELYZA Japanese Llama 2 7B lower by about $1.08 per million blended tokens. Availability is 2 providers versus 2, so concentration risk also matters.
Choose Claude Instant 1.2 when provider fit are central to the workload. Choose ELYZA Japanese Llama 2 7B when provider fit and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
