The conversation in the AI industry has largely been focused on
slowing down AI development
or "pacing the frontier," but that apparently won't stop Anthropic and OpenAI from releasing new models. Both companies are iterating on their previous releases,
Fable 5.1
GPT-6 Astra
, with new models that offer similar levels of performance but at lower costs.
In the case of Claude, Anthropic says its new
Opus 5.5 model
is better at handling complex work, "finding and fixing inefficiencies in software" and financial analysis and business work — all pitches laser-targeted at Anthropic's enterprise customers. Anthropic's benchmarks claim Opus 5.5 also scored better at agentic coding than GPT-6 Astra on both Terminal-Bench 4.0 and FrontierCode v1.1 (Main), which could make it more appealing for developers.
Improvements extend outside of the tasks the model can handle and to how it works: Anthropic claims Opus 5.5 produces writing that's easier to understand, and that it "attempted to circumvent boundaries around 85 percent less often" than past models, suggesting it'll disobey directions less often. Equally important, the company claims it costs less per token to use ($4 for input tokens and $20 for output tokens, compared to the $5 input and $25 output of Opus 5).
OpenAI's new
GPT-6 Sol and GPT-6 Luna models
are similarly focused on efficiency. The new models were trained using similar methods to GPT-6 Astra and offer improvements across professional work, coding and computer use, but for up to 50 percent cheaper than the promotional pricing of their GPT-5.6 counterparts. Specifically, GPT-6 Sol input tokens cost $2, while output tok
