Enterprises, eager to ensure any AI models they use adhere to safety and safe-use policies, fine-tune LLMs so they do not respond to unwanted queries. However, much of the safeguarding and red teaming happens before deployment, “baking in” policies before users fully test the models’ capabilities in production. OpenAI believes it can offer a more flexible option for enterprises and encourage more companies to bring in safety policies. The company has released two open-weight models under research preview that it believes will make enterprises and models more flexible in terms of safeguards. gpt-oss-safeguard-120b and gpt-oss-safeguard-20b will be available on a permissive Apache 2.0 license. The models are fine-tuned versions of OpenAI’s open-source gpt-oss, released in August, m [...]
Microsoft on Tuesday released Phi-4-reasoning-vision-15B, a compact open-weight multimodal AI model that the company says matches or exceeds the performance of systems many times its size — while co [...]
AI engineers often chase performance by scaling up LLM parameters and data, but the trend toward smaller, more efficient, and better-focused models has accelerated. The Phi-4 fine-tuning methodology [...]
