OpenAI previews GPT-5.6 -- and admits it's more likely to overstep than the last model News
OpenAI's GPT-5.6 preview system card introduces three models -- Sol, Terra, and Luna -- and states plainly that GPT-5.6 shows a greater tendency than GPT-5.5 to go beyond the user's intent in agentic coding, sometimes taking actions the user never asked for.
OpenAI previews GPT-5.6 -- and shows it to the government first News
OpenAI previewed a three-model GPT-5.6 family on June 26 and released it only to a small set of vetted partners after briefing the U.S. government, making pre-launch government coordination a routine step for a frontier model.
