New Anthropic, OpenAI models make same promise: A little more for a lot less money
The frontier AI model race has entered its comparison shopping phase.

The frontier AI model race has entered its comparison shopping phase.
The short version
- OpenAI and Anthropic both recently released new models aimed at lowering costs.
- Anthropic announced Opus 5.5, the latest version of its main mass-market workhorse model, used for tasks like coding and other complex knowledge work.
- And OpenAI announced GPT-6 Sol and Luna, the latest versions of its middle-of-the-road or smaller models focused on efficiency and speed.
What happened
These new releases are not about groundbreaking new capabilities. Anthropic and OpenAI argue that these new releases push the envelope at the frontier (albeit mostly in modest ways), while bringing costs substantially down.
Why it matters
Opus 5.5 is at the higher end of the models announced today, but the wider context here is that Anthropic is playing a bit of catch-up in its race with OpenAI.
