Ai2 Releases High-Performance Small Language Model Under Open License

Nonprofit AI research institute Ai2 has released Olmo 2 1B, a 1-billion-parameter AI model that outperforms similarly-sized models from Google, Meta, and Alibaba on several benchmarks. The model is available under the permissive Apache 2.0 license with complete transparency regarding code and training data, making it accessible for developers working with limited computing resources.

Microsoft Launches Powerful Small-Scale Reasoning Models in Phi 4 Series

Microsoft has introduced three new open AI models in its Phi 4 family: Phi 4 mini reasoning, Phi 4 reasoning, and Phi 4 reasoning plus. These models specialize in reasoning capabilities, with the most advanced version achieving performance comparable to much larger models like OpenAI's o3-mini and approaching DeepSeek's 671 billion parameter R1 model despite being substantially smaller.

OpenAI's o3 Reasoning Model May Cost Ten Times More Than Initially Estimated

The Arc Prize Foundation has revised its estimate of computing costs for OpenAI's o3 reasoning model, suggesting it may cost around $30,000 per task rather than the initially estimated $3,000. This significant cost reflects the massive computational resources required by o3, with its highest-performing configuration using 172 times more computing than its lowest configuration and requiring 1,024 attempts per task to achieve optimal results.
