OpenAI and Anthropic Cut API Prices With New Budget AI Models

OpenAI and Anthropic have both unveiled cheaper AI models, a double shot at the budget end of the market. OpenAI's new GPT-6 Sol and GPT-6 Luna slash API prices by 50% compared with the models they follow. Anthropic's fresh Claude lineup, Claude Opus 5.5 included, promises up to 40% in savings on typical workloads versus earlier versions.

The pitch is simple: more tiers, more customers. Both companies are stretching their offerings across price points rather than hanging everything on a single flagship. That opens the door to startups and smaller teams that previously balked at premium API bills.

The catch sits right next to the win. Cheaper models could eat into sales of the pricier products both companies still sell, and that tension is now the number to watch. How much the budget tier cannibalizes the premium tier will shape the longer-term financial picture for both labs.

Next up on the radar: Anthropic's own commentary on financial performance and strategic partnerships, which could move how the market values the company. Investors are also tracking whether heavyweight backers like Amazon and Google shift their investment patterns — a useful signal of how the industry reads these price cuts.

For now, the takeaway is a market getting cheaper fast, with two of the biggest names in AI racing to undercut themselves before anyone else does.
