Deep dive
The capability footprint differs most on function calling: Together AI - Qwen3.5-9B and tool use: Together AI - Qwen3.5-9B. Both models share structured outputs, 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, Together AI - Qwen3.5-9B lists $0.1/1M input and $0.15/1M output tokens, while Together AI Qwen2-7B-Instruct lists $0.15/1M input and $0.15/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI - Qwen3.5-9B lower by about $0.04 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose Together AI - Qwen3.5-9B when provider fit and lower input-token cost are central to the workload. Choose Together AI Qwen2-7B-Instruct when provider fit 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.
FAQ
