Frequently Asked Questions

Everything you need to know about the product and billing.

GPT-5.2 costs $1.75 per 1M input tokens and $14.00 per 1M output tokens. Cached input tokens cost $0.175 per 1M (90% discount). Through EvoLink, pricing is the same as OpenAI direct with the added benefit of one API key across 200+ models.
GPT-5.2 has 400K context vs GPT-5.4's 1.05M, and does not include native computer use or Tool Search. However, GPT-5.2 output pricing ($14.00/1M) is comparable to GPT-5.4 ($15.00/1M), making GPT-5.2 the better value option if you don't need 1M+ context or computer-use capabilities.
GPT-5.2 supports a 400K token context window with 128K max output tokens. This is sufficient for most production workloads including code review, document analysis, and multi-turn conversations.
Yes. GPT-5.2 offers a 90% discount on cached input tokens ($0.175 per 1M vs $1.75 standard). Keep stable system prompts identical across requests to maximize cache hit rates and reduce effective input cost.
Sign up on EvoLink, generate an API key, and set the base URL to EvoLink's endpoint. EvoLink is 100% compatible with the OpenAI SDK — just change the base URL and API key. No code changes needed beyond that.
Yes. GPT-5.2 scores 80.0% on SWE-bench Verified, making it one of the strongest models for code generation, review, and debugging. It handles multi-file codebases well within its 400K context window.
GPT-5.2 offers stronger reasoning and coding performance than GPT-5.1, with the same 400K context and 128K output. Input is $1.75 vs $1.25, and output is $14.00 vs $10.00. Choose GPT-5.1 for simpler tasks where cost matters most; choose GPT-5.2 when you need better accuracy on hard problems.
