Frequently Asked Questions
Is GPT OSS 120B (Fireworks) cheaper than Llama 3.3 70B (Groq)?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), GPT OSS 120B (Fireworks) costs $45.00/month versus $98.50/month for Llama 3.3 70B (Groq) — a 54% 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 OSS 120B (Fireworks) or Llama 3.3 70B (Groq)?
Both GPT OSS 120B (Fireworks) and Llama 3.3 70B (Groq) have the same context window: 131,072 tokens.
Do GPT OSS 120B (Fireworks) and Llama 3.3 70B (Groq) support the Batch API?
GPT OSS 120B (Fireworks) supports the Batch API (50% discount for async processing), while Llama 3.3 70B (Groq) does not. If your workload tolerates up to 24-hour latency, routing to GPT OSS 120B (Fireworks) with batch pricing could significantly cut costs versus Llama 3.3 70B (Groq)'s standard rate.
Which model offers better prompt caching?
GPT OSS 120B (Fireworks) supports prompt caching at $0.08/M for cached input, while Llama 3.3 70B (Groq) does not offer prompt caching. For RAG applications or chatbots with large, repeated context, GPT OSS 120B (Fireworks)'s caching capability can substantially reduce effective costs.
What are the best use cases for GPT OSS 120B (Fireworks) vs Llama 3.3 70B (Groq)?
GPT OSS 120B (Fireworks) is best suited for Code generation, Document summarization, RAG / Semantic search, while Llama 3.3 70B (Groq) is optimized for General chatbot, Customer support. Choose based on which use case matches your primary workload — and validate with the cost calculator above to confirm the total monthly spend fits your budget.
What is the cost per request for GPT OSS 120B (Fireworks) vs Llama 3.3 70B (Groq)?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — GPT OSS 120B (Fireworks) costs $0.000450 per request and Llama 3.3 70B (Groq) costs $0.000985 per request. At 100,000 requests/month, that translates to $45.00 and $98.50 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
GPT OSS 120B (Fireworks) vs Llama 3.3 70B (Groq): Summary
When comparing GPT OSS 120B (Fireworks) and Llama 3.3 70B (Groq) for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. GPT OSS 120B (Fireworks) offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $45.00/month, compared to $98.50/month for Llama 3.3 70B (Groq).
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. GPT OSS 120B (Fireworks) charges $0.15/M for input tokens and $0.60/M for output tokens. Llama 3.3 70B (Groq) charges $0.59/M input and $0.79/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 GPT OSS 120B (Fireworks) but not Llama 3.3 70B (Groq). 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: Both models support 131,072 tokens per request. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
