Price + performance hints
Choosing between OpenAI GPT-4o and Meta AI Meta: Llama 4 Maverick affects your monthly API bill and how snappy your app feels. Skip the hype. Use the calculator above for dollars, then use this page for context limits, caching, and our plain-language hints on speed (0/100 vs 0/100) and rough “smarts” (0/100 vs 0/100). Those hints come from catalog + provider family signals—they are not lab benchmarks—so still try both on real tasks.
API latency and failover paths depend on where you host and which provider region you call. Teams in Australia often verify Sydney (ap-southeast-2) or Singapore edges; US buyers standardize on us-east-1 / us-west-2; Canada frequently maps to the same US regions or dedicated CA endpoints where offered. Our list prices are global list rates—map the model to your closest allowed region in the provider console, then re-run the workspace above with your real traffic split so CFOs and CTOs see numbers tied to production, not a generic blog table.

Benchmark scan pending — live OpenRouter pricing is synced; scores populate after autonomous research. Same idea applies to both sides—use these rows as a starting point, not a verdict.
Every prompt, document, and system message costs input tokens. OpenAI GPT-4o is $2.5 per million input tokens. Meta AI Meta: Llama 4 Maverick is $0.15. For read-heavy workloads, Meta AI Meta: Llama 4 Maverick wins. If you process huge documents daily, that gap adds up fast—pick Meta AI Meta: Llama 4 Maverick 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 Maverick charges $0.6. For long answers, code, or reports, favor Meta AI Meta: Llama 4 Maverick. 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 Maverick allows up to 1,048,576. Meta AI Meta: Llama 4 Maverick 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: Very large — whole codebases or book-scale text in one shot (watch cost).
GPT-4o supports vision (about $0.00765 per image in our catalog). Meta: Llama 4 Maverick 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 Maverick 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 Maverick 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 Maverick is 0/100 (Moderate / variable).
