By PulseAugur Editorial · [1 sources] ·

OpenAI has officially launched GPT-5.6, introducing its Sol and Luna models and rebranding its coding product to ChatGPT Work. This release follows disputed claims of government approval and ongoing concerns about AI model oversight and security vulnerabilities. Concurrently, the AI landscape is heating up with new model releases from competitors, including SpaceX AI's Grok 4.5, which offers competitive coding capabilities at a lower price point, and Meta's Muse Spark 1.1, which shows significant gains in coding and cybersecurity benchmarks. Meta also faced backlash for its Muse Image model, leading to a quick withdrawal. AI
