GPT Image 2.5 Flare
GPT Image 2.5 Flare is OpenAI's fast image generation and editing model in the GPT Image 2.5 family, released September 8, 2026 as the successor to GPT Image 2. It takes text and image input and returns generated or edited images. OpenAI reports it produces higher-quality output than GPT Image 2 at up to 50% lower latency, with improvements in lighting, texture, and consistency when editing from reference images. Within the GPT Image 2.5 family, Flare is the speed-oriented tier. OpenAI positions it as the default choice for creator and social content, product imagery, visual search, rapid prototyping, and high-volume generation, while the companion Sunburst model targets premium workflows that need tighter control over detailed edits. The API exposes quality levels low, medium, high, xhigh, max, and auto. At low quality and 1024x1024 resolution, an image costs $0.00588.
ImageGPT Image 2.5 Sunburst
GPT Image 2.5 Sunburst is an image generation and editing model from OpenAI, released September 8, 2026 as part of the GPT Image 2.5 family alongside a faster sibling model, GPT Image 2.5 Flare. It is built for precision editing workflows, with tighter control over edits, better subject preservation from reference images, and the ability to keep unrelated areas of an image unchanged across multiple edit turns. OpenAI positions it for production-ready campaign creative and polished product imagery, in contrast to Flare's focus on high-volume, everyday generation. Sunburst supports quality levels from low through max, plus auto. At low quality and 1024x1024 resolution, an image costs $0.00588. It runs slower than Flare, trading speed for editing precision.
ChatGPT-6 Astra
GPT-6 Astra is OpenAI's most capable model, released in September 2026 as the successor to GPT-5.6 Sol. It targets complex reasoning, coding, computer use, research, and document creation, taking text and image input over a 1,050,000-token context window and supporting tool calling. OpenAI reports Astra saturates FrontierMath Tier 4 at 97.6% and ARC-AGI-3 at 99.9%, and cuts its hallucination rate from 92% to 51% at max effort versus GPT-5.6 Sol. It is the first OpenAI model to reach the Critical cybersecurity level under OpenAI's Preparedness Framework, scoring 100% on ExploitBench versus 78.5% for GPT-5.6 Sol. Independent testing from Artificial Analysis puts Astra's Intelligence Index at 61.2, roughly level with GPT-5.6 Sol and behind Claude Fable 5.1's 65.7. Input costs $5 per million tokens and output $25 per million, 2.5 times GPT-5.6 Sol's rate.
