Deployment & engineering

On May 7, 2025, OpenAI submitted AI infrastructure proposals to the US Department of Energy, urging federal land use, faster permitting, and financial incentives for AI supercomputer hubs. The post says the first Stargate campus is underway in Abilene, Texas, and more sites are being evaluated in Texas and other states; it does not disclose specific tax, power-pricing, or lease terms. The real signal is policy positioning: OpenAI is framing data centers, energy, and permitting as a national industrial agenda.

Mistral AI released Le Chat Enterprise, an enterprise AI assistant powered by the new Mistral Medium 3 model. It includes enterprise search, an agent builder, connectors for custom data and tools, a document library, custom models and hybrid deployment. All features will roll out over the next two weeks.

Mistral AI released Mistral Medium 3, which it says reaches or exceeds 90% of Claude Sonnet 3.7 across benchmarks. Pricing is $0.4 per million input tokens and $2 per million output tokens.

OpenAI said it raised $40 billion at a $300 billion post-money valuation. The post names SoftBank Group as a partner and says the funds will expand compute infrastructure and support tools for ChatGPT's 500 million weekly users. The AGI framing is broad; the post does not disclose deal structure, funding timing, or product roadmap details.

Mistral AI released a new version of le Chat with iOS and Android apps, Pro and Team tiers, and an Enterprise private preview. It adds a code interpreter, document analysis and image generation, and Flash Answers is in open preview for all users at a claimed ~1000 words per second. Most features are free; Pro starts at $14.99 per month.

Mistral AI released Mistral Small 3, a 24B model built for low-latency tasks, with pretrained and instruction-tuned checkpoints under Apache 2.0. The company says it matches Llama 3.3 70B instruct, runs more than 3x faster on the same hardware, and scores above 81% on MMLU. The model was not trained with RL or synthetic data.

OpenAI introduced sCM and scaled continuous-time consistency models to 1.5B parameters on ImageNet at 512×512. The post says sCM reaches sample quality comparable to leading diffusion models in 2 sampling steps, with about 50x wall-clock speedup. Its largest model generates one sample in 0.11s on a single A100 at batch size 1 without inference optimization.

OpenAI said it raised $6.6B at a $157B post-money valuation. The post says the money will fund frontier AI research, more compute, and product tools; ChatGPT has over 250M weekly users. The investor list, ownership terms, and added compute scale are not disclosed.

OpenAI added automatic prompt caching to GPT-4o, GPT-4o mini, o1-preview, and o1-mini API models, giving a 50% discount on recently reused input prefixes. Caching starts at 1,024 tokens and grows in 128-token increments; caches are often cleared after 5-10 minutes of inactivity and always within 1 hour of last use. The field to watch is cached_tokens in the API usage response.

OpenAI released Structured Outputs on Aug 6, 2024, making model outputs conform to developer-supplied JSON Schemas; `gpt-4o-2024-08-06` scored 100% on complex schema-following evals versus under 40% for `gpt-4-0613`. The feature is enabled with `strict: true` in function calling and works on tool-supporting models including `gpt-4-0613`, `gpt-3.5-turbo-0613`, and later. The key shift is constrained decoding plus schema training, not just valid JSON from JSON mode.
