Together published a guide for building an autonomous data scientist agent using open-source language models and the Together Code Interpreter, implementing a ReAct pattern where the agent reasons in natural language then executes Python code for data analysis tasks. The agent was evaluated on OpenAI's MLE-bench and DABStep benchmarks using DeepSeek-V3, with examples showing it can self-correct when encountering errors like token limit constraints or model convergence issues. The implementation is open-sourced and accessible via a CLI tool that requires only a Together API key, allowing users to run automated data science workflows including data exploration, model training, and report generation.
Together AI announced a partnership with Hypertec and 5C Group to deploy up to 100,000 NVIDIA Blackwell GPUs across Europe, with initial rollouts beginning in late 2025 and large-scale buildouts planned through 2028. The infrastructure will provide 2 gigawatts of AI-dedicated data center capacity with priority deployments in France, the UK, Italy, and Portugal. This enables Together AI to offer European enterprises and developers sovereign, regulation-compliant AI infrastructure for model training, inference, and fine-tuning while maintaining data control.
Featherless AI is now available as a supported inference provider on Hugging Face Hub, allowing users to run models directly through the platform's interface and SDKs. The service supports a catalog of models from DeepSeek, Meta, Google, Qwen and others, with pricing options for direct API calls to Featherless or routed requests through Hugging Face. Users can set custom API keys in account settings, choose providers by preference, and access Featherless models via Python or JavaScript SDKs with no additional markup beyond provider costs.
Mattel and OpenAI are partnering to integrate AI tools into the toy company's brands including Barbie and Hot Wheels.
