GPT API Family
Use one EvoLink API to access every GPT-5 model. Compare GPT-5.4, GPT-5.2, and GPT-5.1 on pricing, context window, reasoning quality, and capabilities — then pick the right model for your workload.
Latest flagship
GPT-5.4 is OpenAI's most capable model — 1.05M context, native computer use, Tool Search, and 128K max output at $2.50/$15.00 per 1M tokens.
Best value
GPT-5.2 delivers strong reasoning and 80.0% SWE-bench at $1.75/$14.00 per 1M tokens with 400K context — the production workhorse.
Budget flagship
GPT-5.1 offers solid performance at $1.25/$10.00 per 1M tokens with 400K context and prompt caching — ideal for high-volume workloads.
Compare the GPT models
Choose based on your primary constraint: reasoning depth, context length, or cost.
| Model | Best for | Input / MTok | Output / MTok | Context | Cached input |
|---|---|---|---|---|---|
GPT-5.4 Flagship | Complex reasoning, 1M+ context analysis, computer use, and agent orchestration. | $2.50 | $15.00 | 1.05M | $0.25 |
GPT-5.2 Best Value | Production coding, reasoning, and multi-turn conversations at 400K context. | $1.75 | $14.00 | 400K | $0.175 |
GPT-5.1 Budget | High-volume tasks where cost matters most: summarization, classification, and generation. | $1.25 | $10.00 | 400K | $0.125 |
Which GPT model should you choose?
Think of the GPT family as three tiers — GPT-5.4 for the hardest work, GPT-5.2 for everyday production, and GPT-5.1 for cost-sensitive volume.
Choose GPT-5.4 if
You need the strongest reasoning, 1M context, or computer use
Pick GPT-5.4 when your workload requires 1.05M context, native computer use for browser automation, Tool Search for complex agent workflows, or the best available reasoning quality. Through EvoLink, output pricing ($12.00/1M) is actually cheaper than base-rate GPT-5.2.
Choose GPT-5.2 if
You want the best price-performance for production
Pick GPT-5.2 when 400K context is sufficient and you want strong reasoning and coding (80.0% SWE-bench) at a lower input cost. Best for multi-turn conversations, code generation, and high-volume automation.
Choose GPT-5.1 if
Cost matters most and simpler tasks dominate
Pick GPT-5.1 when your workload is high-volume and cost-sensitive: summarization, classification, customer support, and straightforward generation tasks. At $1.25/$10.00, it's 29% cheaper on input than GPT-5.2.
