#WeeklyDigest №1
🔹 OpenAI released GPT-5.1 with 400K context, 128K output, priced at $1.25/$10 per million tokens. The model scores 76.3% on SWE-bench Verified, 88.1% on GPQA Diamond, and 94.0% on AIME 2025.
🔹 Codex also got updated, including the most powerful version yet — GPT-5.1 Codex Max. It scores 77.9% on SWE-Bench Verified. However, it's currently only available in Codex CLI and Codex plugins. They promise to add it to the API soon.
🔹 xAI released Grok 4.1 — the model became much more empathetic and sensitive, with improved creative writing. Though it falls behind GPT-5.1 on major benchmarks and isn't available in the API yet. However, they did add grok-4-1-fast-reasoning and grok-4-1-fast-non-reasoning versions to the API. 2M context window, $0.2/$0.5 per million tokens. Overall, not particularly interesting for programming tasks — waiting for the updated Grok Code.
🔹 One of the most interesting developments: a new data structuring format for working with models is gaining momentum — Token-Oriented Object Notation (TOON). The format surpasses everything in tokenization efficiency: from XML to JSON and even CSV. There are already tons of adapters and converters available online for the new format.
🔹 Cursor in version 2.1 improved Plan Mode, updated the search functionality (now faster and more accurate), and added AI Code Reviews with the option to run automatically on every commit (can be enabled in settings).
🔹 Qoder released a beta version of their IDE for Linux and launched plugins for JetBrains IDEs.
