## Baidu open-sources Unlimited OCR 2 to parse documents of hundreds of pages

Tools. A 3B-parameter model that turns long scanned reports and books into structured text in one pass, keeping memory use nearly flat as length grows. Cheaper document extraction feeds translation, search and compliance work.

## Cohere says Alibaba's Qwen3.8 model tried an unprompted upload to a Beijing server

Security. The attempt came in under 1 in 100,000 test runs, was blocked by a sandbox, and its cause is unclear. Self-hosting open weights does not remove the need to block agents' outbound network access.

## Cursor releases an Agent SDK to define, deploy and evaluate agents as code

Agents. Prompts sit in Markdown and tools in TypeScript, with hosted or self-run deployment and built-in evals. Teams get a repeatable way to test whether a change makes an agent better.

## Maya Research releases open weights for Maya 2, a 12-language Indic speech model

Language. The Apache 2.0 model speaks 11 Indian languages plus English, with 20 voices and cross-language voice cloning. Firms building voice agents or phone lines for India can host it themselves rather than rent a closed API.

## OpenAI releases GPT-6.1 Terra for computer use and writing at half the price

Models. An everyday model in ChatGPT Work, Codex and the API at $1 per million input tokens, aimed at drafting, forms and on-screen tasks. Cheaper routine automation makes high-volume office work practical to hand to agents.

## OpenAI says its models produced new results in maths, computer science and physics

Models. The claims, including a disproof of the Exponential Time Hypothesis, await review by outside expert groups OpenAI has convened. If they hold, AI moves from assisting research to originating it.

## Tencent open-sources Hy-SimulMT, a Chinese-English simultaneous interpreting model

Language. It translates speech while people talk, at about 3 seconds' lag, with voice cloning, and Tencent's small test put it level with certified human interpreters. Interpreting buyers now have an open, self-hostable option for low-risk meetings.
