xAI's Grok 4.3 cuts prices

xAI rolled Grok 4.3 into its API with a 1M-token context window and lower token pricing. The release reads less like a flashy leap and more like a cost-performance push for teams building agentic apps on xAI.

// ANALYSIS

xAI is betting that the next wave of model adoption comes from cheaper, fast-enough reasoning rather than another pure benchmark victory lap.

–Official xAI docs now list `grok-4.3` as an API model with a 1M-token input context
–Artificial Analysis reports a higher Intelligence Index score than Grok 4.20, plus a strong jump on real-world agentic tasks
–Pricing appears to have come down sharply versus the prior generation, which matters more for production usage than a marginal leaderboard win
–The positioning is pragmatic: keep Grok competitive on cost while still selling “truth-seeking” and reasoning as the differentiators
–For developers, this is mainly interesting if xAI can sustain low-cost inference without trading away reliability

GLM-5.2 beats Claude Fable 5 in design

Cursor Bugbot adds local pre-push reviews

Cursor has introduced a local `/review` command that allows developers to run Bugbot and security reviews on code changes before pushing them. If a pull request is later opened with the same diff, Bugbot recognizes the local review and skips running again on CI, saving time and resources.
