The AI giants are already shaping the future of their most popular interfaces, and the leaked details reveal a new level of sophistication for ChatGPT, Claude, Gemini, and other emerging models.
OpenAI is preparing GPT-5 for summer 2025, and the leap will be significant.
The new GPT-5 model will be longer, more active, and more integrated: memory, agency, audio, and extended context will redefine the ChatGPT experience.
OpenAI has confirmed that the launch of GPT-5 is expected for summer 2025. Although the exact date has not been officially announced, Sam Altman stated that the release is “likely” in this time window, suggesting an internally ready model in advanced testing.
GPT-5 will likely be fully multimodal, merging text, images, audio, and potentially video, thanks to the maturation of input/output technologies already introduced with GPT-4o. In addition, an extremely long context is expected, estimated between 1 and 2 million tokens, able to handle extensive documents and complex conversational flows without losing semantic memory.
At the same time, OpenAI has already started the initial phases of ChatGPT Agent, a system capable of autonomously carrying out tasks on user request. This is the embryo of the concept of executive AI, which GPT-5 will enhance natively. Persistent memory, partially introduced in 2024, will also be restructured to offer continuity between conversations and evolving personalization.
Anthropic has already launched Opus 4, but the next leap is in memory and continuity.
Claude Opus 4 is already among the most sophisticated models on the market, but the next innovation will make it truly “remember.”
Anthropic released the Claude Opus 4 and Claude Sonnet 4 models in May 2025, focusing on a balance between computational power, coherence, long-term reasoning, and low consumption. Claude Opus 4, in particular, introduced greater operational autonomy for long tasks, establishing itself as one of the most effective models in professional and programmatic contexts.
The next step, already in internal testing on mobile devices, will be true persistent memory. This feature will allow users to resume conversations, documents, and tasks left suspended days or weeks before, without having to recontextualize each time. Claude could thus become the most seamless AI tool for ongoing personal and professional use.
Currently, Anthropic has not announced a new numbered model (like “Claude 5”) but is focusing its efforts on continuous user experience and distributed agentic research. The base architecture remains the Claude 3.5-Opus, but evolved in terms of memory and cross-session logic.
Google is expanding Gemini 2.5 and preparing new levels of specialization.
The Gemini ecosystem differentiates and extends between lightweight, deep, and device-dedicated versions: the future is modular.
In 2025, Google consolidated its Gemini 2.5 model, distributed in the Pro, Flash, Flash-Lite, and Deep Think variants. These configurations cater to different needs: from response speed on mobile devices to the reasoning power required by professionals, developers, and analysts.
The focus has shifted to audio-native capabilities, asynchronous deep thinking, extended contexts (over 1 million tokens), and integration with the Google ecosystem. In particular, the Pro Deep Think and AI Agent Mode versions are already being adopted in Gmail, Docs, Drive, and Android environments.
Google has also launched the Gemini Drops project, a continuous stream of monthly updates introducing new features without waiting for a global release. These include: Gemini Live, which translates voice in real time and integrates with YouTube; Project Mariner, a platform for AI agent developers; and Gemini XR, in prototype phase, designed for mixed reality.
The next numbered model, likely Gemini 3, has not yet been publicly announced, but the Drops suggest ongoing incremental evolution rather than abrupt generational leaps.
AI chatbots are moving toward memory, agents, and multimodal environments.
The trend is convergent: long context, personalization, autonomous execution, and interaction beyond text.
The roadmaps of the leading chatbots show a clear technical and strategic convergence: persistent memory, ultra-extended context, native voice functions, task-executing agents, and multimodal interfaces are the pillars of the new generation.
All leading models are moving in these directions, but with different approaches:
OpenAI wants to create an autonomous conversational assistant with GPT-5.
Anthropic is focusing on coherence, privacy, and semantic depth with Claude 4 and integrated memory.
Google offers modular flexibility with Gemini 2.5, integrating into its mobile and desktop ecosystem.
Meanwhile, other entities are emerging such as xAI with Grok 4, Mistral with its open source models, and Meta AI with Llama 4 and the copilot for Instagram and WhatsApp. The landscape is competitive, but all are gearing up for more lasting, personalized, and less fragmented interaction.
