Executive Summary
Strategic Recommendations
🏆 Best Overall Value: Gemini 1.5 Flash at $0.1875/M blended — approximately half the price of GPT-4o mini and one-tenth the cost of Claude Haiku. Ideal for high-volume, low-complexity tasks where quality thresholds are modest.
🚀 Best Balanced Option: GPT-4o mini at $0.375/M blended offers strong performance-per-dollar for general-purpose applications. The best choice when you need reliable quality without the highest-end model cost.
⚠️ Self-Hosting Caveat: Running Llama 3.1 8B on EC2 g5.xlarge costs ~$734/month (On-Demand) regardless of usage — a significant fixed cost for low-volume workloads. Only break-even at ~110M tokens/month with On-Demand, or ~65M with Reserved Instances. Start with managed services until volume justifies the infrastructure investment.
🧠 For Reasoning Tasks: Claude 3.5 Haiku ($2.40/M) provides strong reasoning capabilities at a fraction of OpenAI’s o-series pricing, making it the budget-conscious choice for tasks requiring complex reasoning without needing premium-priced models like o1-preview ($37.50/M blended).
🚫 Avoid: Running low-volume workloads on self-hosted EC2. The fixed GPU instance cost will always be more expensive than pay-per-token managed services until you process billions of tokens monthly.

Key Findings & Recommendations
Cost Winners by Category:
- Cheapest overall: Gemini 1.5 Flash at $0.1875/M blended — roughly half the price of GPT-4o mini and one-tenth of Claude Haiku.
- Best balanced option: GPT-4o mini offers strong performance per dollar at $0.375/M, making it ideal for general-purpose applications where quality matters but budget is constrained.
- Open-weight alternative: Llama 3.1 8B on Bedrock provides a cost-effective middle ground at $0.22/M with full model control and no vendor lock-in to proprietary models.
Strategic Considerations:
- Idle costs matter: Self-hosted EC2 incurs fixed hourly costs regardless of utilization. For low-volume workloads, managed services (Bedrock/Vertex AI) are significantly cheaper despite higher per-token rates.
- Volume thresholds: The break-even point between Bedrock API and self-hosted EC2 depends on volume — typically 50M–100M tokens/month for 8B-class models.
- Model selection should match workload complexity: Don’t over-provision model capability. Use the cheapest model that satisfies your quality requirements, then upgrade only where needed.
