Both models are closely matched on benchmarks. Nova Lite has the pricing advantage, making it the better value unless GPT-5 Codex's specific capabilities are critical to your workflow.
As of August 20, 2026, Nova Lite is 97% cheaper on blended LLM API pricing. Nova Lite costs $0.06 per million input tokens and $0.24 per million output tokens ($0.30 blended 1M-in + 1M-out). GPT-5 Codex costs $1.25 / $10.00 per million tokens ($11.25 blended). Sources: https://developers.openai.com/api/docs/pricing and https://anotherwrapper.com/tools/llm-pricing. The cheapest LLM for your app still depends on how many output tokens you generate.
GPT-5 Codex OpenAI API pricing is $1.25 input and $10.00 output per million tokens via OpenAI. Nova Lite Amazon API pricing is $0.06 input and $0.24 output per million tokens via Amazon. Use those four numbers, not ChatGPT Plus or Claude Pro subscription prices, when you are comparing APIs.
GPT-5 Codex has a published SWE-bench Verified score of 74.5%. Nova Lite does not have that eval on this page yet.
GPT-5 Codex supports a 400K token context window, while Nova Lite supports 300K tokens. GPT-5 Codex offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Shared benchmark scores for GPT-5 Codex and Nova Lite are still limited. Check the comparison table for the evals each model has published. Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.
Both GPT-5 Codex and Nova Lite are production API models. For cost-sensitive production traffic, Nova Lite has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain. Many production stacks route cheap models for drafts and a frontier model for the hard turn, which is usually cheaper than sending everything to the expensive API.
Yes. Call GPT-5 Codex through OpenAI and Nova Lite through Amazon with separate API keys, or through a gateway that already wraps both. Keep prompts in tokens, not characters, when you estimate the invoice. AnotherWrapper templates can swap providers without rewriting auth and billing.
List rates are the latest published OpenAI API pricing and Amazon API pricing, quoted per million tokens. Official rate sheets: https://developers.openai.com/api/docs/pricing and https://anotherwrapper.com/tools/llm-pricing. Prompt caching, batch APIs, and committed-use discounts can change the invoice. Benchmark scores are from official publications and independent evals, updated as new numbers land.
GPT-5 Codex supports up to an unspecified number of output tokens per request, while Nova Lite supports up to 2K output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
Nova Lite has a measured throughput of approximately 100 tokens/second. Throughput data for GPT-5 Codex is not yet available. Throughput (tokens per second) and time-to-first-token are why two models with the same per-million-token price can still feel different in chat and agents.
