# GPT-4.1

OpenAI, released 2025-04-14

**Verdict: recommended.** The default migration target for GPT-4 Turbo workloads: same request shape, lower cost, 1M-token context — convert legacy function_call payloads to the tools format and move on. Last verified 2026-06-12.

## Pricing

- Input: $2 / 1M tokens
- Output: $8 / 1M tokens

## Strengths

- Drop-in replacement for GPT-4 Turbo chat and completion workloads at lower per-token cost
- Long-context processing up to 1M tokens
- Workloads pinned to the legacy function_call parameter — GPT-4.1 rejects it
