Claude Sonnet 5.5 keeps its predecessor’s API price, but promises cheaper finished work
Anthropic’s new Sonnet ships at $2 per million input tokens and $10 per million output tokens. The claimed savings come from using fewer tokens per task, not a lower token tariff.
SpaceXAI Launches Grok 4.6 With a Focus on Long-Running Agents
SpaceXAI has released Grok 4.6, a model aimed at long-running agents, coding, knowledge work, and interactive projects. It is available in Cursor, Grok Build, the SpaceXAI API, and selected model gateways at the same base token price as Grok 4.5.
Grok Build 1.0 Is xAI’s Bid to Make Terminal Coding Agents Usable Every Day
Grok Build 1.0.0 arrived on August 7, 2026. Its headline is not a new model or benchmark score, but the less glamorous work of making an agent that edits code, runs commands, and keeps working easier to control and recover.
GPT-5.6 after day one: the benchmarks, the caveats, and the real work
OpenAI’s Sol, Terra, and Luna family is now live. Here is what the official scorecards actually say, where independent and early practitioner evidence agrees or pushes back, and which use cases look ready for production testing.
Grok 4.5 gets a Thursday public launch, but the benchmark story is still missing
Elon Musk says xAI will make Grok 4.5 public Thursday after SpaceX and Tesla beta feedback. The model is framed as Opus-class and lower cost, but xAI has not yet published pricing, benchmarks, API details, or a model card.
Loop Engineering: The Complete Guide to Building Self-Improving AI Agents
Stop prompting your coding agents one shot at a time. Here is how to design loops that prompt them for you—and when the extra complexity is worth it.
