Description
GPT-5.6 is rolling out in the API! Our new family of models gives builders three options: Sol (our flagship model for the hardest agentic tasks), Terra (balanced for everyday workflows), and Luna (fast and cost-efficient). GPT-5.6 also introduces Programmatic Tool Calling, Multi-agent (beta) for parallel execution, and explicit prompt caching. On July 23, we're teaming up with Product Hunt for OpenAI Day. The top five launches will each receive $10K in API credits.

Could you build this?
No This is a frontier foundation model release requiring massive compute clusters, petabytes of curated data, and cutting-edge deep learning research.
What it would actually take: Building a frontier foundation model requires tens of thousands of specialized GPUs (e.g., H100/B200 clusters), high-bandwidth networking (InfiniBand), massive distributed training frameworks (Megatron-LM, DeepSpeed), and hundreds of millions of dollars in compute. The specialized expertise spans distributed training algorithms, novel transformer architectures, RLHF/RLAIF pipelines, and massive pretraining data curation.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
