Advancements in AI: Grok 4 Fast and GPT-5-Codex

xAI has launched Grok 4 Fast, pushing the boundaries of cost-efficient intelligence. This model achieves Gemini 2.5 Pro level intelligence at approximately 25 times lower cost. Grok 4 Fast performs near state-of-the-art on various benchmarks, excelling particularly in agentic browsing benchmarks.

Grok 4 Fast combines speed and efficiency with a competitive API price of $0.2 per 1M input tokens and $0.5 per 1M output tokens. It demonstrates efficiency by using only 61M tokens to complete the AA intelligence index.

OpenAI has released GPT-5-Codex, optimized for agentic coding, offering improved performance on long-horizon software tasks. User reviews indicate faster and more intelligent coding outputs.

Meta has garnered attention with the announcement of new smart glasses. The Ray-Ban Meta Display features an in-lens screen for messages, translations, and Meta AI outputs, used in conjunction with the Meta Neural Band.

Alibaba's Tongyi Lab has open-sourced Tongyi-DeepResearch-30B-A3B, achieving parity with OpenAI's Deep Research on information-seeking benchmarks. The model is available on Hugging Face.
