OpenAI Introduces GPT-5 Pro, Sora 2, And A Budget Voice Model At Dev Day

Revolutionizing The Developer Ecosystem

At its latest Dev Day, OpenAI unveiled a transformative suite of API updates that signal a new era of artificial intelligence innovation. At the forefront is Gpt-5 Pro, designed to meet the rigorous demands of industries such as finance, legal, and healthcare with enhanced accuracy and nuanced reasoning.

Elevating Industry Standards With GPT-5 Pro

OpenAI’s introduction of GPT-5 Pro is tailored to developers who require robust, high-performance language models for complex applications. As noted by CEO Sam Altman, the new model is crafted to offer the depth of reasoning necessary for sectors where precision is paramount. This strategic advancement aligns with the broader goal of cementing OpenAI’s ecosystem as the go-to platform for enterprise-level AI solutions.

Voice Capabilities For Real-Time Interaction

Recognizing the importance of voice-enabled applications, OpenAI is concurrently launching the gpt-realtime mini—a cost-effective, smaller voice model optimized for low-latency streaming interactions. At 70% lower cost compared to its predecessor, this model guarantees the same high quality and expressiveness, positioning it as a critical tool for applications that rely on dynamic audio interactions.

Innovative Audio-Visual Synthesis With Sora 2

The company also introduced Sora 2, its latest foray into audio and video generation. Building on the foundation of its previous generation, Sora 2 delivers realistic, physically consistent scenes paired with synchronized sound. This breakthrough enables creative control that ranges from granular camera direction to stylized audiovisual effects, making it an invaluable asset for concept development and creative marketing applications.

For instance, Sora 2 can transform a simple iPhone view into a sweeping, cinematic wide shot or pair a rich ambient soundscape with detailed visuals. Such capabilities underscore OpenAI’s commitment to empowering creators—whether designing engaging advertising concepts or revolutionizing product ideation in collaboration with industry giants like Mattel.

By offering a diverse range of tools that enhance both textual and multimedia content creation, OpenAI continues to drive forward the frontier of artificial intelligence innovation. These latest updates not only appeal to developers but also lay the groundwork for broader transformative applications across multiple industries.

Meta Unveils Muse Wonder Models In A Bid For Frontier AI Leadership

Meta has introduced two new AI models, Muse Wonder and Muse Wonder Full, signalling a more ambitious move into frontier AI. The releases build on Muse Spark but target more demanding tasks, including coding, while placing greater emphasis on long-term memory and personalised assistance.

Larger Models Target More Demanding Tasks

Unlike Muse Spark, which was designed for low latency and lightweight use, Muse Wonder and Wonder Full are significantly larger and, according to Meta, more capable. The company reports stronger benchmark performance and improvements on demanding workloads, including coding.

According to Meta’s model card, both models achieved benchmark results comparable to Fable 5.1 and GPT-6 Astra in the company’s internal testing. Meta described the release as “the next step on our scaling ladder and a major leap toward personal superintelligence” in its announcement.

Pricing Reflects Meta’s Frontier Ambitions

The models’ pricing places them in the premium AI segment. Through the Meta Model API, Muse Wonder will cost $4 per million input tokens and $20 per million output tokens, putting it in a similar pricing tier to GPT-6 Sol and Opus 5.5.

Muse Wonder Full, by contrast, will not be offered through the API. Meta says it will be exclusive to Muse Code subscribers, tying access to its most advanced model to a premium product. Both models will also power the Muse agent.

Long-Term Memory Takes Centre Stage

Meta is increasingly positioning its AI strategy around assistants that can support users over time rather than respond only to individual prompts. A central part of that approach is what the company calls “active memory”: the ability to retain, organise and synthesise information provided by users across extended periods.

Meta points to the MemoryBench benchmark, which evaluates systems designed for continual learning and memory construction. The company says Muse Wonder now outperforms Fable, Opus and Astra on this measure.

“We put a tremendous amount of effort into making sure your model can remember what’s important to you over days, weeks, months, and beyond,” research scientist Kavya Kopparapu said in a launch video.

New Models Follow Meta’s AI Reorganisation

The launch is also significant within Meta’s broader AI strategy. It is the company’s first frontier-model release since Scale AI founder Alexandr Wang reorganised its AI operations in August 2025. Meta has since introduced Muse Spark and the Muse agent, while making fewer high-profile model announcements than competitors such as OpenAI and Anthropic.

The new models were trained at Meta’s Prometheus data centre in central Ohio, which came online earlier in 2026, according to the company. The facility highlights the growing importance of infrastructure in the race to develop advanced AI systems, where performance depends not only on algorithms and data but also on computing capacity, data-centre investment and access to capital.

As competition intensifies, Muse Wonder and Wonder Full represent a broader bet on larger models, persistent memory and premium AI products. Their longer-term significance will depend on how their reported capabilities translate into real-world performance and whether users find enough value to pay for access.
