OpenAI to Discontinue Its Largest Model GPT-4.5 from API Due to Cost Concerns
OpenAI announced it will phase out GPT-4.5, its largest-ever AI model, from its API by July 14, just months after its February release. The company is positioning the newly launched GPT-4.1 as the preferred replacement, citing similar or improved performance at a much lower cost. GPT-4.5 will remain available in ChatGPT for paying customers, but its high computational expenses have made it unsustainable for broader API access.
Skynet Chance (-0.03%): The discontinuation of OpenAI's largest model from wider API access suggests that economic constraints still meaningfully limit the deployment of the most capable AI systems, providing a natural barrier against widespread access to the most advanced capabilities.
Skynet Date (+1 days): The prohibitive cost of running OpenAI's largest model indicates that computational efficiency remains a significant bottleneck, potentially slowing the development and deployment of increasingly capable AI systems until more cost-effective solutions emerge.
AGI Progress (-0.03%): The early discontinuation of GPT-4.5 from the API suggests that simply scaling up models has reached a point of diminishing returns relative to cost, indicating that pure scaling approaches may be hitting economic limitations in advancing toward AGI.
AGI Date (+2 days): The economic infeasibility of maintaining OpenAI's largest model in production suggests that computational constraints may slow the deployment of increasingly large models, potentially extending the timeline for reaching AGI through scaling approaches.
OpenAI Launches GPT-4.1 Model Series with Enhanced Coding Capabilities
OpenAI has introduced a new model family called GPT-4.1, featuring three variants (GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano) that excel at coding and instruction following. The models support a 1-million-token context window and outperform previous versions on coding benchmarks, though they still fall slightly behind competitors like Google's Gemini 2.5 Pro and Anthropic's Claude 3.7 Sonnet on certain metrics.
Skynet Chance (+0.04%): The enhanced coding capabilities of GPT-4.1 models represent incremental progress toward AI systems that can perform complex software engineering tasks autonomously, which increases the possibility of AI self-improvement. OpenAI's stated goal of creating an "agentic software engineer" signals movement toward systems with greater independence and capability.
Skynet Date (-2 days): The accelerated development of AI models specifically optimized for coding and software engineering tasks suggests faster progress toward AI systems that could potentially modify or improve themselves. The competitive landscape where multiple companies are racing to build sophisticated programming models is likely accelerating this timeline.
AGI Progress (+0.06%): GPT-4.1's improvements in coding, instruction following, and handling extremely long contexts (1 million tokens) represent meaningful steps toward more general capabilities. The model's ability to understand and generate complex code demonstrates progress in reasoning and problem-solving abilities central to AGI development.
AGI Date (-3 days): The rapid iteration in model development (from GPT-4o to GPT-4.1) and the intense competition between major AI labs are accelerating capability improvements in key areas like coding, contextual understanding, and multimodal reasoning. These advancements suggest a faster timeline toward achieving AGI-level capabilities than previously expected.
