Cost

OpenAI has released GPT-6.1 Terra, a new mid-range model that halves API prices compared to its predecessor. Early discussions suggest it delivers performance close to larger models like GPT-6-Astra at a fraction of the cost, setting a new standard for intelligence per dollar.

The Neuron reports that OpenAI's GPT-6.1 Terra halves standard API prices and improves computer-use performance, while its safety simulations reveal authorization failures that businesses need to assess alongside task accuracy and review costs.

Based on a transcript excerpt: Matthew Berman reviews Google's announcement of Gemini 4 Carbon, which the company claims is the best model on the planet. He covers the benchmarks, including its top ranking on Artificial Analysis Index V5, its efficiency and lower cost compared to Opus, and its state-of-the-art cybersecurity capabilities, while noting the model has not yet been publicly released.

Simon Willison notes that Anthropic and OpenAI now offer API credits equivalent to $100/$200/$500 subscription tiers, which he says may let him ship public-facing demos since credits are already covered by existing subscriptions.

Ted Sanders says LLM performance is multidimensional, but much variation is explained by model size: bigger models are generally more performant/reliable, cost more per token, and have better recall of esoteric facts.
