DeepSeek releases DeepSeek-V4-Pro on Hugging Face
DeepSeek has released DeepSeek-V4-Pro, a new text-generation model published on Hugging Face under the deepseek-ai organization. The model supports FP8 and 8-bit quantization formats and is tagged as endpoints-compatible with eval results included. With over 4.3 million downloads and 4,740 likes, it has attracted significant community uptake.
DeepSeek V4 Preview Release: 1.6T-param Pro and 284B Flash Models with 1M Context, Open-Sourced
DeepSeek has released DeepSeek-V4 as an open-weights preview, comprising two MoE variants: V4-Pro (1.6T total / 49B active parameters) and V4-Flash (284B total / 13B active parameters). Both models support 1M token context by default, enabled by a novel Token-wise compression and DeepSeek Sparse Attention (DSA) architecture. V4-Pro claims open-source SOTA on agentic coding benchmarks and world-class math/STEM/coding performance rivaling top closed-source models, while V4-Flash offers near-parity reasoning at lower cost and latency. The API is live today with OpenAI and Anthropic compatibility, and legacy model endpoints will be retired in July 2026.
DeepSeek releases DeepSeek-V3.2 on Hugging Face
DeepSeek has released DeepSeek-V3.2, a new text-generation model published on Hugging Face under the deepseek-ai organization. The model supports fp8 precision, is endpoints-compatible, and has accumulated over 3.6 million downloads and 1,446 likes, indicating significant community uptake. This appears to be a successor to DeepSeek-V3, continuing the lab's competitive open-weights model series.
DeepSeek releases DeepSeek-V4-Pro-Base on Hugging Face
DeepSeek has released DeepSeek-V4-Pro-Base, a new base model, on Hugging Face with fp8 and safetensors support. The model has accumulated over 20,000 downloads and 291 likes shortly after release. This represents a new generation in DeepSeek's V-series open-weights frontier models.
OpenAI GPT-5.4 Pro and GPT-5.4 Thinking challenge Gemini 3.1 Pro Preview for top AI model position
OpenAI released GPT-5.4 in two variants (Pro and Thinking), featuring expanded context windows up to 1.05M tokens, native computer use, tool search capabilities, and adjustable reasoning levels. In independent benchmarks by Artificial Analysis, GPT-5.4 Pro at xhigh reasoning nearly ties Gemini 3.1 Pro Preview on the Intelligence Index (57 vs 57.2 points) but at roughly 3.3x the cost, while leading on coding and agentic sub-indices. The release leapfrogs Claude Opus 4.6 on most benchmarks but faces stiff competition from Google's Gemini 3.1 Pro Preview, which maintains a price and multimodal advantage.
GPT-5.4 released with tool search, computer use, and frontier benchmark performance
OpenAI released GPT-5.4 in Thinking and Pro variants, featuring an expanded context window (up to 1.05M input tokens), native computer use, tool search capabilities, and adjustable reasoning levels. In independent testing by Artificial Analysis, GPT-5.4 Pro at xhigh reasoning achieved state-of-the-art on GDP-Val-AA, BrowseComp, Terminal-Bench-Hard, SWE-Bench-Pro, and MCP Atlas, while trailing Gemini 3.1 Pro Preview on MMMU-Pro and Humanity's Last Exam. Pricing is set at the top of the market ($30/$180 per million input/output tokens for Pro), and the release also powers Codex, OpenAI's competitor to Claude Code. The item is reported via The Batch (tier 2 commentary) and includes additional context on Andrew Ng's chub CLI tool for agent documentation sharing.
DeepSeek releases DeepSeek-V3.1 on Hugging Face
DeepSeek has released DeepSeek-V3.1, a new text-generation model published on Hugging Face under the deepseek-ai organization. The model supports fp8 precision, text-generation-inference, and endpoint deployment, and has accumulated over 220K downloads and 824 likes shortly after release. This appears to be an updated iteration of the DeepSeek-V3 series, a frontier-class open-weights model family.
