Anthropic released Claude Haiku 5.5, pricing input tokens at ten cents per million to match competing low-cost models. The update lowers average task costs by up to 90 percent for short requests and cuts Sonnet 5.5 cache reading fees in half.

Space Bunny Alpha is an unreleased experimental model hosted on OpenRouter featuring a context window of one million tokens. It serves developers and researchers seeking to test anonymous frontier models early.

Google introduced Gemini 4 Argon, a model built to automatically identify, confirm, and fix software security vulnerabilities. Cybersecurity defenders are receiving early access before public rollouts to help patch critical infrastructure flaws.

Anthropic released Claude Opus 5.5 with reduced token pricing, followed closely by OpenAI introducing GPT-6 Sol and Luna models. Sol cuts pricing significantly while Luna targets high-volume tasks at a fraction of standard rates. Initial tests highlight a trade-off where heavier reasoning increases response time and cost despite higher benchmark performance.

Access to GrokBot has been bundled into lower tier plans such as Cursor Pro and SuperGrok to lower entry barriers. Meanwhile, OpenAI reduced usage rates for its GPT-5.6 Sol model across input and output processing. These adjustments indicate that companies are encouraging enterprise adoption by making state of the art models cheaper to run.
