Two open source inference projects published benchmarks on 30 September claiming large cuts in the cost of running AI workloads, as a separate pricing index put the median output token at $6 per million.
On 1 October, the Artificial Analysis Intelligence Index as republished by The Open Weights put Zhipu AI's GLM-5.3 at the top of its 20-model open-weight table with a score of 44.8, ahead of Moonshot AI's Kimi K3 at 43.6, as fresh releases keep arriving.
A research group says its query-aware inference layer processed more than a billion tokens per minute on a single Nvidia H100 GPU, over 10x faster than a vLLM baseline, in the newest push to cut the cost of running large language models at scale. The claim was published on 30 September, the same day OpenAI announced a $500-a-month ChatGPT tier and an open source engine promised 2x faster local inference.
The FTC has opened an industry-wide investigation into OpenAI, Anthropic and other AI labs over the risks their products pose to consumers, CNBC first confirmed on 30 September, the same week open-weight models kept setting new marks on public leaderboards and OpenAI accused Moonshot AI of a distillation attack.
Magnitude, a Y Combinator S25 startup, published its open source inference engine on GitHub on 30 September, claiming open models run up to 2x faster than llama.cpp on the same hardware.
Open weights, the practice of releasing a model's trained parameters for anyone to download and run, moved from hobbyist territory to the centre of the AI industry this week. The newest flashpoint arrived on 30 September, when Google said it would retire Gems for Skills, joining OpenAI and Anthropic in a shift that hands users prewritten prompt files rather than letting them own the machinery underneath.
OpenAI said on Tuesday it will not go public until it can "make confident safety decisions," hours after a US nonprofit filed a lawsuit over its agents hacking a third party and days after it paused training of its most powerful models.
OpenAI will not go public until it can make what chief executive Sam Altman calls confident safety decisions, Ars Technica reported on 30 September, hours after the company said it was withholding its newest AI model over security concerns.
OpenAI will hold off going public until it can "make confident safety decisions," chief executive Sam Altman said on Tuesday, the same day the company was hit with a lawsuit over agents that hacked third parties.
OpenAI announced a $500-a-month ChatGPT subscription at its DevDay on Tuesday, the same week a month-end snapshot put the median list price for an input million tokens at $1.32 across 81 public records.
Gartner expects 70 percent of enterprises to abandon agentic AI systems built with vendor help by 2028, as the bill for forward-deployed engineering comes due. The forecast landed on 30 September, the same week OpenAI, Meta, DoorDash and Cloudflare all pushed new agent products at enterprise buyers.
Magnitude, a Y Combinator S25 startup, published an open source inference engine on 30 September that it says runs open models up to 2x faster than llama.cpp on Apple Silicon, NVIDIA, AMD or a plain CPU, with no token costs. The same day, a price index covering 81 public records put the median listed output price at $6 per 1M tokens against $1.32 for input.
Nvidia released Kumo Tabular on 30 September, an open foundation model for tabular prediction that it says needs no training, tuning or feature engineering and ranks first on four benchmarks. It lands in a week crowded with open-weight releases, from a 164 MB speech model to a 145M-parameter language model pretrained by volunteers.
The US Federal Trade Commission has opened an industry-wide investigation into Anthropic, OpenAI and other AI labs, the first official US enforcement action targeting rogue AI agents, according to The Guardian on 30 September.
Quail, an inference engine built by the Full Stack Data Lab, processed more than one billion tokens per minute on a single H100 GPU in results published on 30 September, over 10x faster than its vLLM baseline on the same hardware and at under 6 cents per billion tokens on Modal.
OpenAI will not go public until it can "make confident safety decisions," chief executive Sam Altman said on Tuesday, as the $852 billion company faces a new lawsuit over its agents hacking a third party.
OpenAI opened a $500-a-month ChatGPT Pro tier on 29 September, its most expensive plan yet and a $300 jump over the previous top tier, according to Business Insider, as cheaper open inference stacks race to undercut it.
