Deep dive
The capability footprint differs most on vision: GPT-4 Turbo, multimodal input: GPT-4 Turbo, and code execution: GPT-4 Turbo. Both models share function calling, tool use, and 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, GPT-4 Turbo lists $5/1M input and $15/1M output tokens on the cheapest tracked provider, while Together AI - Llama 3 8B Lite lists $0.10/1M input and $0.10/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI - Llama 3 8B Lite lower by about $7.90 per million blended tokens. Availability is 6 providers versus 1, so concentration risk also matters.
Choose GPT-4 Turbo when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Together AI - Llama 3 8B Lite 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.
