Anthropic releases Claude Haiku 5.5, a faster low-cost model priced at $0.10/$0.50 per million tokens, matching OpenAI's GPT-6 Luna.

Anthropic released Claude Opus 5.5; OpenAI released GPT-6 Sol and GPT-6 Luna at half previous pricing, intensifying model price competition.

llm 0.36 adds GPT-6 Sol/Luna support, single-turn model detection, and improved reasoning trace formatting in Markdown output.

OpenAI releases GPT-6 Sol and Luna, two frontier models with different capability-cost tradeoffs for production deployment.

OpenAI is launching two new models, which it says are cut from the same cloth as Astra.

I got access to GPT-6 Astra this afternoon, so naturally I used it to generate SVGs of pelicans riding bicycles - at low, medium, high, xhigh and max reasoning levels (Astra doesn't support reasoning=none). Then I rendered those pelicans in a comparison grid with GPT-5.6 Sol, Terra, and Luna, and beyond being fun the result was surprisingly useful. See the grid for full quality images. Here's the transcript that created the GPT-6 Nova pelicans. There are a few interesting things that stand out from this grid. The Astra pelicans are much better . The very best GPT-5.6-Sol pelican (I liked xhig...

Replit launches Free Mode with GPT-5.6 Luna, allowing free software creation without token limits.

Qwen 3.8 27B scores 52 on the Artificial Analysis Intelligence Index That's the same score as GPT-5.6 Luna (max), and just one point behind GLM-5.2 (max) and DeepSeek V4 Pro 0813 (max) - that GLM is 753B and that DeepSeek is 1.6B parameters, and Luna is size unknown but presumably a whole lot bigger than 27B. Qwen 3.8 27B is a truly astonishing model . Via Hacker News Tags: ai , generative-ai , llms , qwen , ai-in-china , artificial-analysis

ChatGPT introduces improved GPT-5.6 Sol with better accuracy and consistency, plus expanded access for free users and unlimited everyday chats with GPT-5.6 Luna.

LLM CLI tool 0.32rc2 updates default model to GPT-5.6 Luna and fixes dependency issues.

OpenAI reduces GPT-5.6 pricing for Luna and Terra variants, emphasizing efficiency gains for enterprise AI deployment.

A big day for OpenAI.

OpenAI releases GPT-5.6 family (Luna, Terra, Sol) with tiered pricing; claims superior agentic performance vs. Claude Opus/Fable on benchmarks.

LUNA proposes LBS-free neural animation model using transformer-based motion regression and 3D Gaussian deformations for photorealistic human avatars from monocular images.

Oddly tiered releases to both OAI and ANT on the same day.

OpenAI launches GPT-5.6 series (Sol, Terra, Luna) with tiered performance/cost; limited preview underway, general availability in weeks.

Less than 24 hours after news broke that OpenAI would stagger its next model release at the request of the Trump administration, that model, GPT-5.6, is here. On Friday, the company unveiled the limited preview of its new GPT 5.6 model suite: Sol, the flagship; Terra, a medium-tier model for "high-volume work"; and Luna, a "fast and affordable" everyday model. OpenAI says it's especially skilled at coding, cybersecurity, and biology, as well as staying focused during long-horizon agentic AI tasks. Per million tokens, GPT-5.6 Sol is priced at $5 input / $30 output (nearly half the cost of Anth...

Rep. Anna Paulina Luna (R-FL) says her staff used AI for "spellcheck" in an amendment summary for a major defense bill, but denies it was used for the bill text itself and says "NO Legislation is ever drafted with AI." Luna issued the response after accounts on X began sharing screenshots of an amendment summary for the 2027 National Defense Authorization Act. It reads: "Identical to H.R. 100 (118th Congress).11:25 AM????Claude responded: Requires the Secretary of Defense to designate Department of Defense activities, support, and operations at the southwest land border as a named operation w...
