SpaceXAI Releases Grok 4.7: A Larger Base Model at the Same $2/$6 Price as Grok 4.6

SpaceXAI shipped a meaningfully larger model without increasing cost or latency — a direct challenge to the frontier labs on capability-per-dollar. Practitioners budgeting inference and building agents need to re-evaluate their cost assumptions.

SpaceX launches Grok 4.7 with long-horizon processing, safety upgrades

A new frontier model release with claimed capability upgrades (long-horizon processing, safety improvements) enters the competitive landscape. Practitioners need to know if Grok 4.7 moves the needle on benchmarks or reasoning capability; enthusiasts track the lab-race drama as Musk's model efforts consolidate inside SpaceX.

Jev introduces a new shape of LLM - System One, aka Decision Models

A new model architecture category ('System One') claims to handle reasoning and decision-making differently than scaling transformer chains. If validated, this shapes how practitioners think about model selection and training for agentic workloads.
