Advancing the price-performance frontier with GPT-5.6
Explore lower GPT‑5.6 pricing for Luna and Terra—and how OpenAI’s more efficient models help enterprises deploy AI workflows at scale.
Get smart on it
OpenAI announced price reductions and performance improvements for its GPT-5.6 model family, with the Luna variant costing 80% less and the Terra variant costing 20% less as of the announcement date. The company achieved these gains by making every layer of the models more efficient, including improvements to inference systems, routing, software optimization, and context management. Luna now delivers frontier-level intelligence at substantially lower cost while maintaining the ability to use tools and complete multi-step workflows, making high-volume AI applications more economical to run at scale. OpenAI framed these changes as advancing its mission to make advanced intelligence more abundant and affordable.

Long-horizon agents accumulate context faster than they resolve tasks. Every tool output, observation, and intermediate reasoning step stays in the window, and the two capabilities that matter — holding that context and staying coherent across it — have so far been available almost exclusively from cloud endpoints. That excludes regulated industries, public-sector institutions, and on-device applications, where the data is not permitted to leave the boundary at all. Pokee AI released Pokee-Isaa
Mistral AI Releases Shieldstral 1.0 3B: An Open-Weights Policy-Adaptive Multimodal Safety Classifier Matching Models 7× Its Size
Mistral AI has released Shieldstral 1.0 3B, an open-weights, policy-adaptive multimodal safety classifier that treats content moderation as a single yes/no question rather than a fixed taxonomy of harm categories. Most guardrail models bake their category list into the weights, so re-targeting one to a new deployment context means retraining — and the same content can be acceptable on a cybersecurity research tool while being harmful on a mental-health platform. Shieldstral inverts that: operat
