Engineering Unit Economics Verdict: GPT-6 Luna Architecture, Context Ceiling & GPU Break-Even
1. Multi-Turn Agent Context Overflow Ceiling: With a 1,050,000 token context window and 128,000 max output limit, GPT-6 Luna supports up to 154 consecutive agent turns (at 6,800 cumulative tokens/turn) before requiring sliding-window truncation or summary compression.
2. Prompt Caching & Latency SLA Headroom: Cached input reads on GPT-6 Luna ($0.01/1M) cut input token spend by 90% compared to uncached prompts ($0.10/1M). Hosted on DigitalOcean GPU Droplets (H100 / L40S), Time-to-First-Token averages 210ms (190ms faster than the 400ms real-time voice/chat SLA ceiling).
3. Serverless Token API vs. Self-Hosted vLLM Break-Even: Compared against a dedicated $2,150/mo 80GB H100 GPU instance (DigitalOcean GPU Droplets / Vultr Cloud GPU), serverless token billing for GPT-6 Luna is more cost-effective up to 11,625 Daily Active Users (DAU).
With a massive 1,050,000-token context window, GPT-6 Luna can ingest entire code repositories or multi-document corpora without vector chunking—provided your architecture pins static context at the top of the prompt for prefix caching ($0.01/1M cached read):
- 100,000-Token Full-Repo Prompt (0% Uncached): $10.40 per 1,000 queries
- 100,000-Token Prompt with 90% Prefix Cache Hit: $2.30 per 1,000 queries (saves $8.10 per 1K calls)
- Top-5 Vector RAG Retrieval (4,000-Token Chunk): $0.80 per 1,000 queries (lowest cost when cross-document global reasoning is not required).
