Deep dive
On shared benchmark coverage, Google-Proof Q&A has GPT-5 at 88.4 and Llama 4 Maverick 17B at 67.1, with GPT-5 ahead by 21.3 points; Aider Polyglot has GPT-5 at 88 and Llama 4 Maverick 17B at 15.6, with GPT-5 ahead by 72.4 points. The largest visible gap is 72.4 points on Aider Polyglot, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: GPT-5, reasoning mode: GPT-5, function calling: GPT-5, and tool use: GPT-5. Both models share multimodal input, structured outputs, and code execution, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, GPT-5 lists $1.25/1M input and $10/1M output tokens on the cheapest tracked provider, while Llama 4 Maverick 17B lists $0.24/1M input and $0.97/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Llama 4 Maverick 17B lower by about $3.42 per million blended tokens. Availability is 4 providers versus 1, so concentration risk also matters.
Choose GPT-5 when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Llama 4 Maverick 17B when coding workflow support and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which has a larger context window, GPT-5 or Llama 4 Maverick 17B?
GPT-5 supports 400k tokens, while Llama 4 Maverick 17B supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, GPT-5 or Llama 4 Maverick 17B?
Llama 4 Maverick 17B is cheaper on tracked token pricing. GPT-5 costs $1.25/1M input and $10/1M output tokens. Llama 4 Maverick 17B costs $0.24/1M input and $0.97/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is GPT-5 or Llama 4 Maverick 17B open source?
GPT-5 is listed under Proprietary. Llama 4 Maverick 17B is listed under Open Source. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, GPT-5 or Llama 4 Maverick 17B?
GPT-5 has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Which is better for multimodal input, GPT-5 or Llama 4 Maverick 17B?
Both GPT-5 and Llama 4 Maverick 17B expose multimodal input. The better choice depends on benchmark fit, context budget, pricing, and whether your provider route exposes the same capability surface.
Where can I run GPT-5 and Llama 4 Maverick 17B?
GPT-5 is available on Replicate API, OpenRouter, OpenAI API, and Vercel AI Gateway. Llama 4 Maverick 17B is available on AWS Bedrock. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
