Altman’s Roadmap to GPT-4.5, GPT-5

OpenAI is preparing to release GPT-4.5, internally codenamed “Orion,” as its final incremental language model before transitioning to a brand new AI architecture. Initial reports indicated that Orion delivered only marginal improvements over GPT-4, reinforcing the concept scaling traditional language models is approaching its practical limits. Fairly than deploying o3 as an independent release, OpenAI is integrating it into GPT-5—a system designed to autonomously determine when to have interaction in complex reasoning, leverage external tools, and adapt dynamically across tasks.

GPT-5 represents a strategic shift away from OpenAI’s fragmented AI offerings, consolidating multiple ChatGPT versions, API models, and have sets right into a unified intelligence framework. The model will integrate capabilities similar to voice interaction, search, and advanced research right into a single system.

OpenAI can also be introducing a tiered access model: free users will interact with the usual version, Plus subscribers will access an enhanced reasoning layer, and Pro users will unlock the best level of performance. This transition aligns with OpenAI’s investment in Large Reasoning Models (LRMs), which have already propelled its o3 model into the highest 50 global coding benchmarks.

By combining the final linguistic capabilities of LLMs with the structured precision of reinforcement-trained reasoning models, OpenAI is positioning GPT-5 as a more adaptive and functionally robust AI system. Read more.

Perplexity AI has launched an upgraded version of its Sonar search model, now powered by Meta’s Llama 3.3 70B and optimized with Cerebras Systems’ specialized hardware. In internal tests, Sonar outperforms models like GPT-4o mini and Claude 3.5 Haiku in user satisfaction, and competes closely with premium models like GPT-4o and Claude 3.5 Sonnet in search accuracy.

The important thing to Sonar’s speed lies in Cerebras’ Wafer Scale Engines, massive chips able to processing 1,200 tokens per second. This enables Sonar to generate responses nearly immediately, setting a brand new standard for AI-powered search. Currently, Sonar is on the market exclusively to Pro users, though Perplexity plans to expand access soon. Details on the financial terms of their partnership with Cerebras remain under wraps.

Elon Musk announced that Grok 3, xAI’s chatbot and competitor to OpenAI’s ChatGPT, is in its final development phase and set to launch inside two weeks. Speaking via video on the World Government Summit in Dubai, he claimed Grok 3 exhibits superior reasoning capabilities, outperforming all existing chatbots.

Through the same address, Musk warned that human intelligence will soon be dwarfed, stating that digital intelligence will comprise “greater than 99% of all intelligence in the long run.” He also referenced futurist Ray Kurzweil’s predictions that humans may eventually merge with machines, accessing cloud computing directly with their brains.

Musk has long positioned brain-computer interfaces, similar to those developed by his company Neuralink, as a option to keep pace with AI. Read more.
