#Model release

AIReflection AI has introduced Beam, an open agentic model with 501B total parameters and 23B active, trained end-to-end from scratch. The company says Beam advances the Western open frontier on coding and agentic tasks, with full weights set for release this month.

AIReflection is set to release Beam, its first open-weight AI model, aiming to become a Western counterpart to DeepSeek. The source says Beam is trained from scratch for coding, reasoning, and AI agents, with benchmarks placing it alongside the strongest open models and more efficient token economics. Reflection has raised $4.6 billion from investors including Nvidia, Sequoia, and Lightspeed, and the interview covers its monetization plans for open-weight models.

AILiquid AI released d1 with vision support, accepting images, text, or both as inputs. In tests on six real applications, d1 matched or beat GPT-6.1 Sol on four while costing 19x to 200x less than both GPT-6.1 Sol and Claude Opus 5.5. It returns probabilities for yes/no, choice, or score questions in one forward pass, with text decisions in 200 to 300 ms.

AILiquid AI's vision-enabled decision model d1 inspects parts directly from camera images and is described as the best such model currently on the market. It reaches 85% to 97% accuracy across four VisA inspection tasks covering circuit boards, candles, cashews, and chewing gum. It understands each task from a short description without task-specific training.

AILiquidAI has released d1-omni-600M on Hugging Face, a 587M-parameter model that answers named yes/no, choice and score questions over text, images or up to 30 seconds of speech in a single forward pass. It returns typed answers with zero output tokens by reading the model's distribution over options, and is built on LFM2.5-Encoder-350M with a 16,384-token context length. The model is not a chat model and does not generate text.

AIUpstage's Solar Mini 4 is free on Nous Portal for the next two weeks. The model has 3B active parameters out of 35B total and a 512K context window. It scores 24 on the Artificial Analysis Intelligence Index, above models with roughly 10x the active parameters.

AIReplit shipped a weekly update letting users build with GPT-6.1 Sol and Claude Sonnet 5.5, along with an Ask agent integration with Jev. The release also includes an updated Settings UI and enterprise Workplace controls for company-wide rules and controlled exceptions. Full details are in the Replit changelog.

AILiquid AI has released d1-3B, a 3B parameter multimodal model post-trained to return calibrated, typed answers to yes/no, choice, and score questions in one forward pass. The source reports a Decision Index 0.2.1 score of 48.57, the highest among models under 10B in its table, and 8 ms per decision on an NVIDIA RTX 4090.

Why it matters: The source gives benchmark scores against named peer models and edge latency figures across several hardware targets, helping readers judge fit for on-device decision pipelines.

AILiquid AI introduces d1, its first decision model, now accepting both text and images. The company says d1 matches or beats GPT-6.1 Sol on four of six tested applications, at 19x to 200x lower cost and with faster answers on every task. d1 is available on the Liquid AI API and through Vercel and OpenRouter, with text-only support on those two platforms for now.

Why it matters: The post gives benchmark comparisons against named models along with per-token pricing and latency figures, which makes the cost and speed tradeoff checkable.

The quantized checkpoint shows a 5.73% perplexity increase over the BF16 original (3.5011 to 3.7017) on a fixed corpus, and its zh-en and en-zh outputs are semantically equivalent under greedy decoding. Full FP4 acceleration requires an NVIDIA Blackwell GPU, while the source recommends the FP8 build for Hopper and Ampere hardware.

AIAleph Alpha has released Kolibri, a model with 78B total parameters, 3.46B active, and up to 1M tokens of context, under Apache 2.0. The quoted post says the weights can be run on the user's own hardware. Cohere's own post is a short endorsement of the release.

AIAntigravity has added Claude Opus 5.5 and Sonnet 5.5 for all paid users, according to Varun Mohan. The post also expresses enthusiasm for a broader rollout of Gemini 4 Argon.

AICohere evaluated North Small Translate on WMT26 benchmarks, which were released after the model was created, so the model could not have been trained on them. This timing is presented as a safeguard against training contamination in the reported measurements.

AIAlephAlpha has released Kolibri, a German-English model with 78B total parameters, 3.46B active, and context up to 1M tokens. The weights are available under Apache 2.0 for running on users' own hardware. Cohere's Aidan Gomez congratulated the team on the model and its detailed technical report.
