Frequently Asked Questions
Is GPT-5.4 Nano cheaper than Llama 4 Scout (Fireworks)?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), Llama 4 Scout (Fireworks) costs $30.00/month versus $82.50/month for GPT-5.4 Nano — a 64% saving. Your actual savings will vary based on your token profile; output-heavy workloads amplify differences in output pricing.
Which model has a larger context window, GPT-5.4 Nano or Llama 4 Scout (Fireworks)?
Llama 4 Scout (Fireworks) has a larger context window at 10,000,000 tokens, compared to 400,000 tokens for GPT-5.4 Nano. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do GPT-5.4 Nano and Llama 4 Scout (Fireworks) support the Batch API?
Llama 4 Scout (Fireworks) supports the Batch API (50% discount for async processing), while GPT-5.4 Nano does not. If your workload tolerates up to 24-hour latency, routing to Llama 4 Scout (Fireworks) with batch pricing could significantly cut costs versus GPT-5.4 Nano's standard rate.
Which model offers better prompt caching?
Llama 4 Scout (Fireworks) supports prompt caching at $0.10/M for cached input, while GPT-5.4 Nano does not offer prompt caching. For RAG applications or chatbots with large, repeated context, Llama 4 Scout (Fireworks)'s caching capability can substantially reduce effective costs.
What are the best use cases for GPT-5.4 Nano vs Llama 4 Scout (Fireworks)?
Both models are well-suited for General chatbot. GPT-5.4 Nano is particularly strong for overlapping tasks. Llama 4 Scout (Fireworks) is favored for Customer support, RAG / Semantic search. At the same quality level, the lower-cost model is usually preferable; use this page's calculator to compare total monthly spend at your volume.
What is the cost per request for GPT-5.4 Nano vs Llama 4 Scout (Fireworks)?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — GPT-5.4 Nano costs $0.000825 per request and Llama 4 Scout (Fireworks) costs $0.000300 per request. At 100,000 requests/month, that translates to $82.50 and $30.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
GPT-5.4 Nano vs Llama 4 Scout (Fireworks): Summary
When comparing GPT-5.4 Nano and Llama 4 Scout (Fireworks) for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. Llama 4 Scout (Fireworks) offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $30.00/month, compared to $82.50/month for GPT-5.4 Nano.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. GPT-5.4 Nano charges $0.20/M for input tokens and $1.25/M for output tokens. Llama 4 Scout (Fireworks) charges $0.20/M input and $0.20/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 Llama 4 Scout (Fireworks) but not GPT-5.4 Nano. 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: Llama 4 Scout (Fireworks) supports up to 10,000,000 tokens in a single request, versus 400,000 tokens for GPT-5.4 Nano. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
Use the interactive calculator at the top of this page to enter your actual token usage and monthly request volume for a precise cost comparison tailored to your workload. Adjust for batch API discounts and prompt caching to find the most cost-effective option for your specific deployment.
