Deep dive
The capability footprint differs most on vision: Phi 4 Multimodal Instruct, multimodal input: Phi 4 Multimodal Instruct, and structured outputs: Together AI Deepseek-LLM-67B-Chat. 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, Phi 4 Multimodal Instruct lists $0.9/1M input and $0.9/1M output tokens, while Together AI Deepseek-LLM-67B-Chat lists $0.6/1M input and $0.6/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI Deepseek-LLM-67B-Chat lower by about $0.3 per million blended tokens. Availability is 3 providers versus 1, so concentration risk also matters.
Choose Phi 4 Multimodal Instruct when long-context analysis, larger context windows, and broader provider choice are central to the workload. Choose Together AI Deepseek-LLM-67B-Chat 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.
