Gemini 3.1 Pro vs Llama 3.3 70B Instruct (Fireworks): Summary
When comparing Gemini 3.1 Pro and Llama 3.3 70B Instruct (Fireworks) for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. Llama 3.3 70B Instruct (Fireworks) offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $135.00/month, compared to $800.00/month for Gemini 3.1 Pro.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Gemini 3.1 Pro charges $2.00/M for input tokens and $12.00/M for output tokens. Llama 3.3 70B Instruct (Fireworks) charges $0.90/M input and $0.90/M output. If your workload is output-heavy (more tokens generated than consumed as input), the model with the lower output price compounds cost savings significantly at scale.
Prompt caching is supported by both models. For workloads with large, repeated system prompts or document context — such as RAG pipelines or multi-turn conversations with a fixed knowledge base — prompt caching can reduce effective input costs by 60–90%, which may change the cost ranking between these two models at your specific usage pattern.
Context window capacity differs between the two: Gemini 3.1 Pro supports up to 2,097,152 tokens in a single request, versus 131,072 tokens for Llama 3.3 70B Instruct (Fireworks). A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
