GPT-4.1 is OpenAI's general purpose model built around a 1 million token context window, letting it reason over very large documents, full codebases, and long conversation histories in a single call. OpenAI reports it was trained to keep reliable attention across the full context length, with notable improvements in coding and instruction following over GPT-4o. It is multimodal, supporting text and image inputs, and produces structured output that conforms to a supplied JSON schema. Function calling lets it compose external tools into agentic workflows. The model suits applications that need deep document analysis, code generation with broad context, complex reasoning over large corpora, and tool-using agents.
GPT-4.1 runs on 1 route through the Opper gateway. Compare residency, ZDR, and training posture at a glance — full data-handling detail per route below.
| Provider | Region | Zero data retention | Training | Input | Output |
|---|---|---|---|---|---|
| US | Not by default | No | $2.00 | $8.00 |
GPT-4.1 runs on a single route through the Opper gateway today, so its availability is that provider's availability.
Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider Opper monitors.
Each route hosting GPT-4.1 has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
Zero data retention is not on by default — abuse monitoring, 30-day retention. No training on customer data. US; SCCs; DPA available.
Independent benchmark scores — composite indices for reasoning, coding, and math, plus individual eval scores where available.
Call GPT-4.1 through the Opper gateway with one API key. Let your coding agent set it up, or call it directly — Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.
Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up Opper for you.
