#Model release

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.

AIThis Latent Space AINews roundup compiles a weekend's AI news from Twitter and Reddit rather than a single announcement. It covers OpenAI's GPT-6.1 Sol pricing and Agent Arena placement, Anthropic's Sonnet 5.5 debut, Meta's open-sourced Muse hardware firmware, and several research and benchmark items, many reported with unverified claims.

AIvLLM Semantic Router has released Decision 2.0, featuring open models ranging from 0.6B to 27B parameters. The models can answer 64 questions about a request in a single forward pass, are licensed under Apache-2.0, and load with Transformers.

AIOllama has published Clef Flash and Clef as new models in its model library, with links to their library pages. The post provides no further details on parameters, benchmarks, or capabilities.

AIAs of October 2, 2026, GitHub deprecated Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7 across all Copilot experiences. Suggested replacements are Gemini 3.8 Flash, Kimi K3, and Claude Opus 5.5, and Enterprise administrators may need to enable them through model policies.

AIRamp Router is offering Grok 4.7 at 50% off through October 6, in a partnership with SpaceXAI to lower token costs. Developers can get an API key at router.com to access the discounted model.

AIGitHub has made the Project HydraFusion research preview available in the GitHub Copilot app and @code, where it orchestrates multiple models rather than acting as a single model. New models from Anthropic (Fable 5.1 and Opus 5.5) and OpenAI (GPT-6.1 Sol) are also now selectable in the Copilot model picker.

AIOpenCode is offering inclusionAI's latest model, Ling-3.1-flash, for free. The model has 560B total parameters, 25B active parameters, and a 262K context window.

AIAnt Ling has made Ling-3.1-flash available on OpenRouter at no cost, inviting users to try it and share feedback. The post provides no details on model size, benchmarks, context length, or pricing beyond the free access.

AIKilo Code is offering Ling 3.1 Flash for free until October 13, with the model served by Novita Labs. Ant Ling's background post describes the model as roughly 560B total parameters with about 25B active per token and a context window of up to 1M tokens. Ant Ling says it scores 1,673 Elo on GDPVal-AA v2.1, 75.16 on FrontierSWE, and 65.35 on HealthBench Professional, and plans to open-source it soon.

AIAi2 released AstaBrief 8B, an open-weights model that turns a research question and retrieved literature excerpts into a cited report, along with its training data. The model runs as Fast mode in Asta, averaging 51.1 seconds per report versus 178.5 seconds for Thinking mode, about 3.5x faster. The post also describes filtering synthetic training data by citation density and building DPO pairs judged by two models that agreed.

Why it matters: The post explains how supervised fine-tuning, preference data, and citation-density filtering were used to build a cited-report model, which is useful for teams training their own models.

AIinclusionAI has released Ling 3.1 Flash, a hybrid reasoning mixture-of-experts model with 560B total parameters, of which 25B are active. The source does not provide benchmark scores, pricing, context length, or availability details.

AIAi2 released AstaBrief 8B, a model that turns a research question and retrieved literature excerpts into a cited report, along with its training data. In Asta's Generate a report feature, Fast mode averages 51.1 seconds per report versus 178.5 seconds for Thinking mode, about 3.5x faster. The model is built on Qwen3-8B with supervised fine-tuning and DPO, and institutions can run its open weights on their own infrastructure.

Why it matters: The post explains the data filtering and one-pass generation choices behind a fast open-weights report model, showing what worked and what did not.

AITinker says Fulcrum trains its Echo writing model by building on a base model that already writes well, tailoring both SFT and RL to separate the default LLM voice from authors' voices. The post calls this customization approach both cheap and effective. Fulcrum says Echo beats frontier models at writing tasks such as fiction and technical explanations, at a training cost under $5K.

AIOpenAI says GPT-6.1 Sol is now good, cheap, and fast, after slow speeds caused by a load spike in its first two days. A global reset for all paid ChatGPT accounts is scheduled for Friday, October 2, at 10AM PT.

AICloudflare says it is releasing two decision models it trained, Clef and Clef-flash. The main post links to a blog post with details, but the text provided gives no further specifications, benchmarks, or pricing.

AINVIDIA has released PixelUMM, an encoder-free unified multimodal model with 15,199,672,064 parameters that handles text, image, and video understanding and generation directly in pixel space. It represents images as 16-by-16 RGB pixel patches on a Qwen3-8B language backbone, with iterative denoising for generation. The checkpoint is licensed for non-commercial research or evaluation only, while the source code is under Apache License 2.0.

AIPerplexity open-sourced pplx-decider-27b, a state-of-the-art multimodal Decision Model, and offers it through a new Decisions API. Input tokens cost $0.04 per million and output tokens are free, with further price cuts promised in the coming days.

AIKrea (@krea_ai) shared a link to a page for an image model it refers to as "bfl-3-image." The post gives no further details on capabilities, pricing, or release terms.

AIVercel says the Laya decision model is available free on AI Gateway through October 31, in partnership with Boundless. The post suggests using it to route agent work, triage support requests, and check guardrails.

AIHiggsfield AI has made FLUX 3 Image available to try on its platform, linking directly to its image generation page with the flux-3-image model selected. The post provides no details on capabilities, pricing, or benchmarks.

AIARC Prize has published full ARC-AGI results for Alibaba's Qwen3.8-27B, with the testing run hosted by Baseten. The post links the public leaderboard, the open-source benchmarking repository for reproducing the results, and the testing policy.

AIBlack Forest Labs says customers can contact the company for commercial weights for its FLUX 3 image model. The post also points users to a playground to try the model and to a product page with more information.

AIBlack Forest Labs is discounting its FLUX 3 Image model by 50% through its API until October 8th. The company is also making FLUX 3 Image available under a commercial weights license, letting companies fine-tune it and deploy it on their own infrastructure.

AIReplicate says it is powering Griffin from Tavus on its platform. Tavus describes Griffin as the first model to pass the video Turing test, with 48% of live conversation participants believing it was a real human. The model ranks first on NVIDIA's full-duplex AI video benchmark.

AILiquid AI's d1 model is now available through OpenRouter, as the post says demand for it has been very high. The post notes that users can now access it easily via the OpenRouter platform.

AIPerplexity has published the weights for pplx-decider-v1-27b, a model fine-tuned from Qwen3.8-27B with a 250k-token context window. The weights are available on Hugging Face, and the post points developers to the Perplexity Decisions API quickstart for getting started.

AIMicrosoft Copilot begins rolling out OpenAI's GPT-6.1 Sol and Anthropic's Claude Sonnet 5.5 today, joining Claude Opus 5.5 and GPT-6 Sol added earlier this month. Users can pick the model suited to each task, with Work IQ grounding responses in their files, meetings, and chats within existing permissions. The rollout starts today in Copilot Cowork and Copilot Studio, with Word, Excel, PowerPoint, and Chat following in phases over the coming week.

AICloudflare has open-sourced Clef and Clef-Flash, its first homegrown decision models, now available on Workers AI. Harrison Chase praised the release as an open-weights entrant and argued that agent harnesses should be able to swap their decision model as easily as their main model.
