Deep dive
The capability footprint is close: both models cover function calling, tool use, and structured outputs. That makes context budget, benchmark fit, and provider maturity more important than a simple checklist. If your application depends on one integration detail, verify it against the provider route you plan to use, not just the base model listing.
For cost, Grok Code Fast 1 lists $0.2/1M input and $1.5/1M output tokens, while Together AI - Llama 3 8B Lite lists $0.1/1M input and $0.1/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI - Llama 3 8B Lite lower by about $0.49 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose Grok Code Fast 1 when coding workflow support and larger context windows 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. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
