- 6The New Stack·7/29/2026product_launchCursor, Anthropic, and OpenAI localize India pricing for AI plans
Cursor launched a lower-priced India-only plan, Cursor Start, billed in rupees and supporting UPI payments, positioning it below its standard Pro tier. Anthropic has also introduced rupee pricing for Claude in India, but its converted dollar prices remain above US equivalents and UPI support is not yet available, while OpenAI previously launched ChatGPT Go in India with local pricing and UPI support.
- 8Hacker News·7/24/2026model_releaseFlux 3 Early Access Released
FLUX 3 is a new multimodal foundation model that jointly learns from images, videos, audio, and language in a single architecture. The company says it can generate and transform video with native audio, support text-to-video and image-to-video workflows, and has shown early preference results over competing video models in preliminary evaluations.
- 7The New Stack·7/23/2026product_launchCursor Launches a Model Router to Optimize Coding Requests
Cursor has introduced a model router that routes each coding request to the model best suited for the task, balancing cost, speed, and capability. The company says early users saved 30-50% versus sending all requests to Opus 4.8, while Cursor also continues building its own in-house and frontier model stack.
- 7Simon Willison·7/15/2026open_sourceGrok Build is Open Source
xAI has published the Grok Build repository on GitHub, making the project publicly available under an open-source license. The release lets developers inspect, reuse, and potentially contribute to the build system behind Grok-related components.
- 8The New Stack·7/11/2026model_releaseOpenAI, SpaceXAI and Meta spark an AI price war
OpenAI, SpaceXAI, and Meta each launched or expanded new AI models within a 24-hour window, but the shared headline was pricing rather than capability. The article argues that frontier AI is increasingly competing on lower token costs and efficiency, signaling growing pressure on margins across leading model providers.
- 6The New Stack·7/8/2026model_releaseGrok 4.5, GPT-5.5, and Claude Compared on Coding Builds
A Hacker News post compared Grok 4.5, GPT-5.5, Claude Opus 4.8, and Claude Fable 5 on three one-shot coding tasks: a 3D Rubik's Cube, a particle gravity sandbox, and a Breakout game. The results showed different strengths across visual quality, physics behavior, and speed/cost, with Grok 4.5 standing out on latency and throughput while the Claudes excelled on the Rubik's Cube task.
- 7The New Stack·7/8/2026model_releasexAI to launch Grok 4.5 publicly on Thursday
Elon Musk said xAI will make Grok 4.5 publicly available on Thursday after beta testing, describing it as an Opus-class model that is faster, more token-efficient, and lower cost. The report says the model is based on xAI’s 1.5-trillion-parameter V9 foundation model and may have received additional coding data from Cursor, while Musk also hinted at a larger V-series model coming in August.
- 8Hacker News·7/8/2026model_releaseGrok 4.5 announced and discussed on Hacker News
The Hacker News discussion centers on Grok 4.5, with the linked Cursor blog post serving as the source of the announcement. The thread drew significant attention, suggesting strong interest in xAI’s latest model update and its implications for AI capabilities and developer workflows.
