OpenAI Launches GPT-5 with Major Reasoning Upgrades
OpenAI's new flagship model improves multi-step reasoning, tool use and long-context handling. Here's what changed and why it matters.
What's new in GPT-5
OpenAI has officially launched GPT-5, its most capable model to date. The release focuses on three pillars: reasoning, tool use, and long-context understanding.
Improved reasoning
GPT-5 handles multi-step problems more reliably than GPT-4, with measurably fewer hallucinations on complex math and coding benchmarks. OpenAI reports a significant jump on GPQA and SWE-Bench.
Better tool use
The model can now orchestrate multiple tools in a single turn — searching, running code, and calling APIs without losing the thread of a conversation.
1M token context
A 1-million-token context window lets you feed entire codebases or book-length documents into a single prompt.
Pricing and availability
GPT-5 is available to Plus, Team, and API users now. The API pricing is higher than GPT-4-class models, reflecting the added capability.
Our take
GPT-5 is a meaningful step forward, especially for developers who rely on AI for complex, multi-step work. If you've been on the fence about upgrading, the reasoning gains alone justify it.
