OpenAI’s new GPT-4 5 model is a better, more natural conversationalist

GPT-3.5 Turbo tokens are also 3x cheaper than they were for the previous version of GPT-3.5 with the 16K context window at $0.001, while output tokens are also half price, costing just $0.002 per token. This means that the language model is only available as a preview right now. I the pattern of its prior releases continues, ChatGPT Plus and Enterprise customers will be the first to gain full access. Training GPT-5 is estimated to consume as much energy as a small city for a year around 500 gigawatt-hours. Grok 4’s deployment on the Colossus supercomputer, utilizing over 200,000 GPUs, further underscores the sustainability challenge.

ChatGPT’s Reduced Pricing Model

In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3. The free tier of ChatGPT will get unlimited chat access to GPT-5 at the standard intelligence setting (!!), subject to abuse thresholds. Despite its relative strengths over GPT-4o and o3-mini, GPT-4.5 isn’t a direct replacement for those models. This is particularly important if you’re using it to generate anything that you’ll be sharing with clients or customers. As you may be aware, ChatGPT and other AI tools like Bard have a tendency to “hallucinate” – so proofreading and fact-checking the content they produce for you is essential, not optional.

• It’s more powerful than the previous two language models that were used to power ChatGPT, GPT-4 and GPT-3.5.
• GPT-5 and Grok 4 are largely “black boxes,” complicating regulatory oversight and public trust.
• The risk of “automation bias” where humans defer to AI over their own judgment threatens to undermine critical thinking and personal agency.
• Yet, harmonization remains a challenge, and cross-border data sharing, interoperability, and redressal mechanisms are still in early stages.

OpenAI envisages people building them for tasks at home and in the workplace, and then sharing these creations with others. Grok 4 has been piloted for real-time crisis mapping during Southeast Asian floods, integrating live sensor and social media data to support disaster response. GPT-5 is being trialed by legal firms in the EU for automated contract review and regulatory compliance, demonstrating its utility in high-stakes, knowledge-intensive domains. Claude 4 and DeepSeek R1 are powering multilingual tutoring platforms in Africa and India, bridging gaps in teacher availability and educational access.

OpenAI just released GPT-4.5 and says it is its biggest and best chat model yet

GPT-4 is also significantly better at enforcing its own content moderation policy than other OpenAI models, responding to disallowed content requests 82% less frequently than ChatGPT-3.5. But how does GPT-4 differ from ChatGPT-3.5 and other AI tools, and is it really that much more intelligent? Your workplace’s guidelines on the type of task you can ask ChatGPT to help you with may be linked to the sort of data they’re happy with you sharing with it, so it’s always good to check.

Its top-tier performance on coding benchmarks and real-time web search capabilities make it a favorite among developers and operational teams. However, its rapid-release philosophy and relatively less conservative alignment present both opportunities for innovation and risks of misuse. Tokens – the basic units that large language models process – are now going to be a lot cheaper on several GPT models. OpenAI describes tokens as pieces of words; input tokens are the pieces of words that make up prompts, whereas output tokens make up responses. Speaking of reduced hallucinations, OpenAI measured how much better GPT-4.5 in that regard.

Open-source models like Llama 4 and DeepSeek R1 enable community auditing and reproducibility, but the leading commercial models remain closed, limiting independent scrutiny. According to the white paper, GPT-4.5 excelled at donation conning because of a unique strategy it developed during testing. It’s now possible to run useful models from the safety and comfort of your own computer.

Unlike reasoning models such as o1 and o3, which work through answers step by step, most large language models like GPT-4.5 spit out the first response they come up with. Grok 4, on the other hand, is engineered for agility and real-time interaction. With a 130,000-token context window and native integration with the X platform, it excels in coding, rapid deployment, and live data ingestion.

What’s more, OpenAI claims that GPT-4.5 responds with far fewer made-up answers (known as hallucinations). On the same test, GPT-4.5 made up answers 37.1% of the time, compared with 59.8% for GPT-4o and 80.3% for o3-mini. “The key to creating intelligent systems is a recipe we’ve been following for many years, which is to find scalable paradigms where we can pour more and more resources in to get more intelligent systems out,” says Ryder.

We want AI to “just work” for you; we realize how complicated our model and product offerings have gotten. OpenAI boss Sam Altman has masterfully stolen back the news cycle by pretty much laying out the future of ChatGPT. Altman posted what he called an OpenAI roadmap update for both GPT-4.5 and GPT-5 AI models. GPT-4.5 was also better than all of OpenAI’s models at deceiving GPT-4o into telling it a secret codeword, besting o3-mini by 10 percentage points. Some people believe chatbots like ChatGPT can provide an affordable alternative to in-person psychedelic-assisted therapy. Impressively, in a demo that took place on Tuesday, GPT-4 was able to explain was able to build a website based on a basic hand-drawn sketch provided by a human.

People are using AI to ‘sit’ with them while they trip on psychedelics

Workers across the globe are finding new, inventive ways to use ChatGPT every day. However, using such a powerful tool to cut down on the time you’re spending on tasks comes with a variety of different considerations. Developers that are using the 4K context window version of GPT-3.5 Turbo will have their token prices reduced by 33% (now $0.001).

Their arrival compels us to confront urgent questions of sovereignty, security, equity, ethics, and the very future of human agency. OpenAI has just released GPT-4.5, a new version of its flagship large language model. The company claims it is its biggest and best model for all-round chat yet. “It’s really a step forward for us,” says Mia Glaese, a research scientist at OpenAI. However, OpenAI’s GPT-4 Turbo chatbot has knowledge of events up until April 2023.
