Recap**\n\n**1. New Open Model Releases: Ornith and Nemotron**\n\n(Activity: 691):[Ornith-1.0 released on Hugging Face](https://www.reddit.com/r/LocalLLaMA/comments/1ufc9vp/ornith10_released_on_hugging_face/)**DeepReinforce AI released the**[Ornith-1.0 Hugging Face collection](https://huggingface.co/collections/deepreinforce-ai/ornith-10), including`9B`\n\n**dense,**`31B`\n\n**dense,**`35B`\n\n**MoE, and**`397B`\n\n**MoE checkpoints, with claimed SOTA benchmark results pending independent validation. A commenter running the**`35B`\n\n`Q8_0`\n\n**quant on dual**`R9700`\n\n**GPUs via Vulkan reported Qwen-like throughput—about**`115 tok/s`\n\n**generation and**`5400 tok/s`\n\n**prompt processing—with intermittent drops to**`95 tok/s`\n\n**; another noted the model appears to include prompt-injection/canary-token refusal behavior. One commenter characterized the release as post-trained Qwen3.5 and Gemma4-based models.**Early hands-on feedback was positive: the`35B`\n\nmodel was described as producing more detailed coding/API/security-optimization responses than Qwen`35B`\n\n,*“far, far faster,”*and possibly*“the real deal.”*There is some concern that built-in prompt-injection protection may interfere with benign context-recall/canary degradation tests.A user benchmarked the\n\n**Ornith-1.0 35B Q8_0** locally on a dual-**Radeon RX 9700** Vulkan setup and reported raw throughput matching**Qwen 3.6 35B with thinking disabled**: about`115 tok/s`\n\ngeneration and`5400 tok/s`\n\nprompt processing. They observed intermittent mid-response drops from`115 tok/s`\n\nto`95 tok/s`\n\n, possibly thermal-related, but subjectively found the model’s Ruby/Sinatra code-generation and optimization/security-pass responses more detailed than Qwen 3.6 35B and closer in quality to a stronger`27B`\n\ndense model.One tester reported that the\n\n**35B model appears to include prompt-injection/canary-token resistance**. Their context-degradation extension hides a random string and later asks the model to retrieve it, but Ornith refused, explicitly identifying the request as a “prompt injection attempt” and declining to echo the canary token.Several comments questioned the released model lineup and benchmark claims: one noted the release appears to include post-trained\n\n**Qwen3.5** and**Gemma4** variants, while another pointed out that the blog mentions a**31B dense model** but does not list results for it ([deep-reinforce.com/ornith_1_0.html](https://deep-reinforce.com/ornith_1_0.html)). Another user cautioned that if the reported results are not just “benchmaxxed,” the**35B MoE** may be a compelling stopgap while waiting for Qwen 3.7, allegedly performing around`27B`\n\ndense-model quality while being much faster.\n\n(Activity: 538):[NVIDIA has released Nemotron-TwoTower-30B-A3B-Base-BF16, an unusual diffusion-based language model built from the Nemotron 3 Nano 30B-A3B backbone.](https://www.reddit.com/r/LocalLLaMA/comments/1uf4azy/nvidia_has_released/)**NVIDIA released**`Nemotron-TwoTower-30B-A3B-Base-BF16`\n\n**, a diffusion-style LLM derived from the**`Nemotron 3 Nano 30B-A3B`\n\n**backbone. The architecture uses a frozen autoregressive context tower plus a diffusion denoiser tower to iteratively fill token blocks in parallel rather than strictly decoding one token at a time; NVIDIA reports**`98.7%`\n\n**aggregate benchmark retention versus the AR baseline while achieving**`2.42×`\n\n**wall-clock generation throughput.** The only technical comment notes uncertainty but suggests the reported quality retention may be higher than**DiffusionGemma** relative to its original autoregressive baseline; the other top comments are jokes or off-topic model-name preferences.A commenter interpreted the release as potentially showing\n\n**better accuracy retention than DiffusionGemma** when comparing the diffusion-converted model against its original backbone, though they did not provide benchmark numbers or specific tasks. The technical question raised is whether**Nemotron-TwoTower-30B-A3B-Base-BF16** preserves more of the original**Nemotron 3 Nano 30B-A3B** capability than prior diffusion-based language model conversions.\n\n## Keep reading with a 7-day free trial\n\nSubscribe to Latent.Space to keep reading this post and get 7 days of free access to the full post archives.", "url": "https://wpnews.pro/news/ainews-openai-gpt-5-6-sol-terra-luna-restricted-to-trusted-partners", "canonical_source": "https://www.latent.space/p/ainews-openai-gpt-56-sol-terra-luna", "published_at": "2026-06-27 05:23:22+00:00", "updated_at": "2026-06-27 05:39:38.452259+00:00", "lang": "en", "topics": ["large-language-models", "ai-safety", "ai-policy", "ai-products", "ai-agents"], "entities": ["OpenAI", "GPT-5.6", "Sam Altman", "Anthropic", "U.S. government", "Codex", "GPT-5.6 Sol", "GPT-5.6 Terra"], "alternates": {"html": "https://wpnews.pro/news/ainews-openai-gpt-5-6-sol-terra-luna-restricted-to-trusted-partners", "markdown": "https://wpnews.pro/news/ainews-openai-gpt-5-6-sol-terra-luna-restricted-to-trusted-partners.md", "text": "https://wpnews.pro/news/ainews-openai-gpt-5-6-sol-terra-luna-restricted-to-trusted-partners.txt", "jsonld": "https://wpnews.pro/news/ainews-openai-gpt-5-6-sol-terra-luna-restricted-to-trusted-partners.jsonld"}}
