OpenAI launched the gpt-realtime model and Realtime API to GA, featuring advanced speech-to-speech capabilities, new voices (Cedar, Marin), image input, SIP telephony, and a ~20% price cut. Benchmarks show improvements over gpt-4o-realtime on BigBench and ComplexFuncBench. xAI introduced Grok Code Fast 1, a speed-optimized coding model integrated with popular IDEs, while OpenAI Codex received major upgrades for local and cloud development workflows. Google’s Gemini CLI improved multi-editor support, and new models like Microsoft MAI-1-preview and MAI-Voice-1 were announced. "The new all-in-one WebRTC API removes the ephemeral token step and supports video on the same connection," highlighting enhanced developer tooling.

OpenAI launched GPT-5 with a unified user experience removing manual model selection, causing initial routing and access issues for Plus users that are being addressed with fixes including restored model options and increased usage limits. GPT-5 introduces "Priority Processing" for lower latency at higher price tiers, achieving ~750ms median time-to-first-token in some cases. Microsoft reports full Copilot adoption of GPT-5, and API traffic doubled within 24 hours, peaking at 2 billion tokens per minute. Early benchmarks show GPT-5 leading in reasoning tasks like FrontierMath and LiveBench, with improvements in hallucination control and creative writing, though some models like Grok-4 and Claude-4 Sonnet Thinking outperform it in specific RL-heavy reasoning benchmarks. OpenAI also released extensive migration and feature guides but faced some rollout issues including a broken code sample and a problematic Voice Mode launch. "Unified GPT-5" ends model pickers, pushing developers away from manual model selection.

Alibaba Qwen released their QwQ-32B model, a 32 billion parameter reasoning model using a novel two-stage reinforcement learning approach: first scaling RL for math and coding tasks with accuracy verifiers and code execution servers, then applying RL for general capabilities like instruction following and alignment. Meanwhile, OpenAI rolled out GPT-4.5 to Plus users, with mixed feedback on coding performance and noted inference cost improvements. The QwQ model aims to compete with larger MoE models like DeepSeek-R1. "GPT-4.5 is unusable for coding" was a notable user critique, while others praised its reasoning improvements due to scaling pretraining.

OpenAI plans to release its first open-weight language model since GPT-2 in the coming months, signaling a move towards more open AI development. DeepSeek launched its open-source R1 model earlier this year, challenging perceptions of China's AI progress. Gemma 3 has achieved function calling capabilities and ranks on the Berkeley Function-Calling Leaderboard, while GemmaCoder3-12b improves code reasoning performance on LiveCodeBench. Alibaba_Qwen's Qwen2.5-Omni introduces a novel Thinker-Talker system and TMRoPE for multimodal input understanding. The TogetherCompute team achieved 140 TPS on a 671B parameter model, outperforming Azure and DeepSeek API on Nvidia GPUs. OpenAI also expanded ChatGPT features with image generation for all free users and a new voice release. Runway Gen-4 enhances animation for miniature dioramas, and LangChain launched a chat-based generative UI agent. Commercial deployment of Figure 03 humanoid robots at BMW highlights advances in autonomy and manufacturing scaling. New tools include OpenAI's realtime transcription API with WebRTC support and Amazon's Nova Act AI browser agent.

OpenAI has launched three new state-of-the-art audio models in their API, including gpt-4o-transcribe, a speech-to-text model outperforming Whisper, and gpt-4o-mini-tts, a text-to-speech model with promptable prosody allowing control over timing and emotion. The Agents SDK now supports audio, enabling voice agents. OpenAI also updated turn detection for real-time voice activity detection (VAD) based on speech content. Additionally, OpenAI's o1-pro model is available to select developers with advanced features like vision and function calling, though at higher compute costs. The community shows strong enthusiasm for these audio advancements, with a radio contest for TTS creations underway. Meanwhile, Kokoro-82M v1.0 emerges as a leading open weights TTS model with competitive pricing on Replicate.

OpenAI launched the o1 API with enhanced features including vision inputs, function calling, structured outputs, and a new reasoning_effort parameter, achieving 60% fewer reasoning tokens on average. The o1 pro variant is confirmed as a distinct implementation coming soon. Improvements to the Realtime API with WebRTC integration offer easier usage, longer sessions (up to 30 minutes), and significantly reduced pricing (up to 10x cheaper with mini models). DPO Preference Tuning for fine-tuning is introduced, currently available for the 4o model. Additional updates include official Go and Java SDKs and OpenAI DevDay videos. The news also highlights discussions on Google Gemini 2.0 Flash model's performance reaching 83.6% accuracy.
