GPT-4.1

by OpenAI

All OpenAI releases

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.

Uptime and availability

GPT-4.1 runs on a single route through the Opper gateway today, so its availability is that provider's availability.

94.61%route uptime, last 30 days

Single route, no failover target within this model.

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.

Data handling per route

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.
