Llama 4 Maverick vs OpenAI GPT-4.1 — API Pricing, 150K Cache & Latency Benchmark
Side-by-side unit economics audit comparing Llama 4 Maverick (llama-4-maverick: Input $1/1M, Output $4/1M, Warm Cache Read $0.1/1M) against OpenAI GPT-4.1 (openai/gpt-4.1: Input $2/1M, Output $8/1M, Warm Cache Read $0.5/1M).
Activate 4-breakpoint prefix caching on Llama 4 Maverick to cut input token costs from $1/1M down to $0.1/1M, or route async workloads via Batch API for 50% off.
Lock static system prompt prefixes on OpenAI GPT-4.1 to pay $0.5/1M warm cache rates instead of $2/1M uncached input, plus eligible startup cloud credits.
In Etuki FinOps telemetry comparing Llama 4 Maverick (API ID: llama-4-maverick) vs OpenAI GPT-4.1 (API ID: openai/gpt-4.1), Llama 4 Maverick offers lower standard uncached input pricing at $1/1M tokens, while Llama 4 Maverick leads in 10-turn 150K cache-pinned coding economics at $0.3650 per 10 turns (saving $0.7700 over OpenAI GPT-4.1). For latency-sensitive interactive agents, OpenAI GPT-4.1 delivers 66ms faster P90 time-to-first-token (410ms vs 476ms).

1. Full-Turn Rate-Card Substitution for Llama 4 Maverick: At an uncached input rate of $1/1M, output rate of $4/1M, and warm cache read rate of $0.1/1M, running 10 consecutive 150,000-token coding agent turns (with 2,000 output tokens/turn) without prefix pinning costs $1.5800. Locking 100% static prefixes (Case A: 1 cold turn + 9 warm cached turns + 20K total output) reduces 10-turn spend to $0.3650 (saving $1.2150); under a 90% static prefix + 10% dynamic tail workload (Case B), 10-turn spend is $0.4865.
2. Full-Turn Rate-Card Substitution for OpenAI GPT-4.1 & Winner Verdict: On OpenAI GPT-4.1 ($2/1M input, $8/1M output, $0.5/1M warm cache), 10 unpinned 150K turns cost $3.1600, dropping to $1.1350 in Case A and $1.3375 in Case B. Across every 10-turn 150K coding loop (including output tokens), Llama 4 Maverick delivers an additional $0.7700 Case-A cost advantage.
Production Workload TCO: 25,000 MAU • 50M Tokens/Mo (50% Cache Hit) • 2,000 GB Egress
💡 Optimal FinOps Verdict: Deploying Llama 4 Maverick saves $68.00/month ($816/year) at 25,000 MAU & 50M monthly tokens (80% input / 20% output split with 50% prefix cache hit rate).
