OpenAIGPT-4ovsMeta AIMeta: Llama 4 Scout: API Pricing Comparison & Performance Calculator

Every prompt, document, and system message costs input tokens. OpenAI GPT-4o is $2.5 per million input tokens. Meta AI Meta: Llama 4 Scout is $0.08. For read-heavy workloads, Meta AI Meta: Llama 4 Scout wins. If you process huge documents daily, that gap adds up fast—pick Meta AI Meta: Llama 4 Scout over OpenAI GPT-4o when quality is similar. Use our calculator above to see exact input costs.

Output tokens are what the model generates. They are usually pricier than input. OpenAI GPT-4o charges $10 per million output tokens; Meta AI Meta: Llama 4 Scout charges $0.3. For long answers, code, or reports, favor Meta AI Meta: Llama 4 Scout. Tight prompts ("answer in one paragraph") cut spend on either side. Our calculator helps you estimate these output costs accurately.

Context is how much text fits in one request. OpenAI GPT-4o allows up to 128,000 tokens. Meta AI Meta: Llama 4 Scout allows up to 327,680. Meta AI Meta: Llama 4 Scout fits longer docs or repos—but you pay for every token you send, every turn. Do not max the window unless you need it. In plain words: Standard for chat + medium docs; chunk bigger sources. For the other side: Strong for long reports, transcripts, and mid-size repos.

GPT-4o supports vision (about $0.00765 per image in our catalog). Meta: Llama 4 Scout is text-only here. Resize images before the API when you can—it lowers token load and cost.

Reusing the same long context? Caching can slash input cost. GPT-4o lists cached input around $1.25 per million tokens. Meta: Llama 4 Scout does not show a cached rate here. Great for chat over one big PDF or policy doc.

If you do not need instant replies, batch jobs often run at a steep discount (often around half off list price, depending on the provider). Ship a file of requests, get results within about a day. Ideal for summaries, translations, and backfills. Use the calculator toggles above to see how batch mode changes your estimate.

Chats repeat system prompts and history every turn. A short user message can still bill thousands of input tokens. Lower input price helps—Meta AI Meta: Llama 4 Scout is usually safer for high-volume chat. On our speed hints, OpenAI GPT-4o is 0/100 (Moderate / variable) and Meta AI Meta: Llama 4 Scout is 0/100 (Moderate / variable). If one is clearly ahead on both price and speed hint, that is a nice combo for live chat—but slow networks or huge prompts can still swamp the difference, so try a realistic thread in your region.

Extraction needs accuracy and often a large context for messy PDFs. Try both OpenAI GPT-4o and Meta AI Meta: Llama 4 Scout on real samples. If quality matches, pick the cheaper input side—extraction is usually input-heavy.

Coding rewards reliability over saving a few cents. Bad output costs engineer time. Our coding-strength hints (again, heuristics) put OpenAI GPT-4o at 0/100 and Meta AI Meta: Llama 4 Scout at 0/100, with broader “smarts” hints at 0/100 vs 0/100. Between this pair, favor whichever passes your tests on your stack traces and style rules; if quality is a tie, output price leans toward Meta AI Meta: Llama 4 Scout for long patches.

System prompts ride along on every call. Example: 1,000 tokens × 100,000 requests per day ≈ 100M input tokens daily. At $2.5 per million for OpenAI GPT-4o, that is about $250.00 per day from the system prompt alone. Keep instructions short and reusable.

RAG sends retrieved chunks with each question. More chunks mean more input tokens to OpenAI GPT-4o or Meta AI Meta: Llama 4 Scout. Tighten retrieval: send only the best few passages, not whole folders.

Long prompts tax you every request. Fine-tuning costs upfront but can shorten prompts. Compare total cost in our calculator: long prompt + cheap base model vs short prompt + fine-tuned pricing if you use it.

Agents may call OpenAI GPT-4o or Meta AI Meta: Llama 4 Scout many times per user task. One workflow can equal dozens of normal chat turns. Cap steps, log spend, and alert on spikes.

Bill clients for API usage you resell. Use Agency Mode in the calculator for markup, client price, and margin—plus PDFs for proposals.

Flat plans get burned by power users on OpenAI GPT-4o or Meta AI Meta: Llama 4 Scout. Credits or BYOK (bring your own key) align revenue with cost.

Dashboards, alerts, and tools like Helicone or Langfuse show who burns tokens and which prompts bloat bills. Measure before you optimize.

Beyond this pair, consider Anthropic Claude 3.5 Sonnet, Google Gemini Gemini 1.5 Pro, or OpenAI GPT-4o Mini for price or capability fit. Design your stack so you can swap models without a rewrite.

List prices keep falling, but workloads get heavier—bigger contexts, agents, more tools. Net spend can still climb. Keep a running estimate whenever you change models or traffic.

Cost is not everything. GPT-4o carries a speed hint of 0/100 (Moderate / variable); Meta: Llama 4 Scout is 0/100 (Moderate / variable).Tuned for low-latency product UX versus o-series reasoning models. Self-hosted latency is determined by your infra. In production you still want time-to-first-token and tokens per second on your prompts, region, and concurrency—especially for voice, typing indicators, or anything that feels “live.”

Check training, retention, and region rules for each provider behind GPT-4o and Meta: Llama 4 Scout. Regulated data needs enterprise terms, not guesswork.

Proprietary APIs are simple but price-controlled. Open models (e.g. Llama family) add ops work but can cut unit cost at scale. Match the tradeoff to your team.
