Budget Model Insights

Cheapest per Token

Llama 3.1 8B at $0.10/$0.10 per 1M tokens is the absolute cheapest. Best for high-volume, latency-tolerant workloads where you control the infrastructure.

Cheapest Managed API

GPT-oss 20B at $0.08/$0.35 is the cheapest managed API with 1M context. Google's free tier makes it even better for low-volume projects.

Best Value Overall

DeepSeek V4 Flash at $0.14/$0.28 delivers strong quality at budget prices with 1M context. The best bang-for-buck in 2026.

Longest Context

Llama 4 Scout (1M context) at $0.18/$0.59. Unmatched for document-heavy workloads — if you can handle dedicated inference.

Best from OpenAI

GPT-oss 20B at $0.08/$0.35 is OpenAI's cheapest model. Good for simple classification, extraction, and summarization tasks.

Sweet Spot: Under $50/mo

With 100K requests/month, most budget models cost under $50. That's 5-10x cheaper than premium models for workloads that don't need them.
