OpenAI has officially launched GPT-5, its most advanced language model to date, and made it widely available across ChatGPT, the API, and GitHub Models. The company says GPT-5 delivers major gains in coding, reasoning and context handling compared with prior models. (OpenAI, The GitHub Blog)
CEO Sam Altman described GPT-5 as a “significant step” toward more capable AI, while stopping short of calling it artificial general intelligence. Early coverage says the rollout includes new user-facing features and broader access for free and paid ChatGPT tiers. (WIRED)
Key features and cost
OpenAI released GPT-5 in multiple variants — gpt-5, gpt-5-mini and gpt-5-nano so developers can choose performance versus cost trade-offs. The API pricing is published at \$1.25 per 1M input tokens and \$10 per 1M output tokens for the full model, with lower rates for the mini and nano tiers. The model also supports a very large context window for long documents and multi-turn workflows. (OpenAI Platform)
For Pakistani developers and teams, that means powerful reasoning at a predictable per-token cost but actual monthly bills will depend on usage, integration patterns and local exchange rates.
Why developers care
OpenAI says GPT-5 outperforms predecessors on coding benchmarks and real-world developer tasks, making it well suited for tools like GitHub Copilot and other agentic workflows. Early benchmarks cited by OpenAI show improved scores on software-engineering tests.
GitHub has already added GPT-5 to GitHub Models and begun rolling GPT-5 into Copilot plans, so many developers will see the model in their editors and CI pipelines soon.
Safety, accuracy and oversight
OpenAI reports reductions in hallucination rates and improved safety from extensive red-teaming and validations, but it warns the model is not perfect and remains prone to errors on some queries. Independent coverage notes both enthusiasm and calls for careful external review as adoption grows.
What Pakistani users should watch
- Access: ChatGPT users will see GPT-5 routed according to their plan; developers can call the API or use GitHub Models/Copilot.
- Costs: API costs are listed in USD; convert cautiously for local budgeting.
- Use-cases: Expect gains for coding help, document analysis, long-form drafting and multi-step workflows.
- Safety: Avoid treating outputs as authoritative for legal, medical or high-risk decisions without professional verification.
