Chain of Thought
Explore O1 Mini & O1 Preview models with Chain-of-Thought (CoT) reasoning, balancing cost-efficiency and deep problem-solving for complex tasks.
Fine-tuning
OpenAI’s latest update marks a significant leap in AI capabilities by introducing vision to the fine-tuning API. This update enables developers to fine-tune models that can process and understand visual and textual data, opening up new possibilities for multimodal applications. With AI models now able to "see"
OpenAI
This update is welcome news for developers who have been grappling with the challenges of managing API costs and response times. OpenAI's Prompt Caching introduces a mechanism to reuse recently seen input tokens, potentially slashing costs by up to 50% and dramatically reducing latency for repetitive tasks. In
Benchmarks
OpenAI's new "omni-moderation-latest" model shows significant improvements over the legacy model, especially in multilingual performance and image moderation. We benchmark it's capabilties with it's predecessor.
Production Guides
This is a guest post by Ganaraj, based on the talk he gave at the LLMs in Prod Meetup in Bangalore. AI has fundamentally changed the way we build apps. I transitioned from being a coder to a creative prompter. This shift from coding to creative prompting might seem like
