OpenAI

GPT-6 Astra is OpenAI's September 2026 flagship for the hardest end-to-end reasoning, coding, computer use, research, and document work. The API model ID is gpt-6-astra, with a 1,050,000-token context window, 128,000 max output tokens, text and image input, and reasoning.effort from low through max. OpenAI's safety overview (September 3, 2026) states Astra is the first broadly deployed OpenAI model to reach the Critical cybersecurity capability level under the Preparedness Framework.

Anthropic

Claude Fable 5.1 is Anthropic's September 1, 2026 generally available flagship for demanding reasoning and long-horizon agentic coding, research, and document work. The API ID is claude-fable-5-1, with a 1M-token context window, 128K max output, adaptive thinking, and default high effort. Anthropic keeps the $10/$50 input/output list price of Fable 5 while cutting cache reads to $0.25 per million tokens.

Google

Gemini 3.8 Flash is Google's September 2, 2026 workhorse for software engineering, agentic tasks, and multi-step reasoning at Flash speed. The DeepMind model card documents text, image, audio, and video input, a 1M-token context window, 64K output, and adjustable effort levels. Google keeps the same introductory price as 3.7 Flash: $0.75 input and $3.75 output per million tokens through December 31, 2026.

Google

Gemini 3.8 Live is Google's September 15, 2026 default Live API model for low-latency voice agents and real-time dialogue. The stable model code is gemini-3.8-live. It takes text, images, audio, and video, and returns text and audio, with a 131,072-token input limit and 65,536-token output limit. Google positions it for scale and cost efficiency: interleaved reasoning, asynchronous function calling, 97-language mid-conversation switching, and visual grounding while the session keeps talking. Audio sessions are listed at $0.005 per minute input and $0.018 per minute output on the developer Live post.

TypeSafe AI

Jev is TypeSafe AI's first System One model, launched in early access on September 15, 2026. It is not a chatbot: you send unstructured or structured state plus typed questions and get structured answers your code can branch on. The documented model alias is jev-latest on POST https://api.typesafe.ai/v1/systemone. Question primitives are Choice (up to 255 options), Score, and Noul (yes/no probability). TypeSafe lists $0.042 per million input tokens with output tokens unmetered, and 70–500 ms end-to-end on its launch workloads. Training is Reinforcement Learning for Calibrated Decisions (RLCD).

OpenAI

GPT-Live-1 is OpenAI's full-duplex voice model for real-time spoken conversation. The API ID is gpt-live-1. It listens and speaks at the same time, handles interruptions, and delegates reasoning and tool use to a backend agent instead of doing that work itself. OpenAI's system card (July 8, 2026) introduced it as the paid ChatGPT voice default. The API launch post (September 10, 2026) documents Live sessions, native ASR transcripts and response text, keyword biasing, and turn detection. Voice sessions are billed $0.05 per minute, per second. Backend model and tool usage is billed separately.

Meta

Muse Spark 1.3 is Meta's September 2, 2026 hosted model for long-horizon agentic and coding work. The API ID is muse-spark-1.3, with a 1,048,576-token context window, text/image/video/PDF input, and text output. Meta documents it in Muse Code and Meta Model API, with reasoning effort including max on the Standard tier. Official docs still list muse-spark-1.2 as the Muse Code default while recommending 1.3 for new API work.

DeepSeek

DeepSeek-V4.1-Flash is DeepSeek's September 10, 2026 multimodal Mixture-of-Experts model and the smallest member of its new architecture family. The live API ID is deepseek-flash. Official materials describe a 552B-parameter Causal Encoder–Decoder MoE that activates 8B parameters on input and 16B on output, native image-and-text understanding, and a 1-million-token context. DeepSeek says V4.1-Flash outperforms DeepSeek-V4-Pro on performance, cost, speed, and total runtime. Weights are on Hugging Face under MIT.

SpaceXAI

Grok 4.6 is SpaceXAI's frontier model for coding, long-running agents, knowledge work, and interactive visual projects. Official documentation lists text and image input, text output, a 500,000-token context window, configurable low through xhigh reasoning, function calling, web and X search, code execution, and the API model ID grok-4.6.

Z.ai

GLM-5.3-Flash is Z.ai's first natively multimodal GLM-5 model: a 320B-parameter mixture-of-experts checkpoint with 18B active parameters, hybrid sparse and linear attention, and MIT-licensed weights. Z.ai documents API access as glm-5.3-flash, Coding Plan and ZCode availability, and Hugging Face weights for SGLang, vLLM, and TokenSpeed.

Alibaba Qwen

Qwen3.8-Max is Alibaba Qwen's hosted 2.4-trillion-parameter mixture-of-experts flagship for coding, professional work, multimodal analysis, and long-horizon agents. Effective September 5, 2026 (UTC+8), the qwen3.8-max endpoint automatically serves the September 2 snapshot qwen3.8-max-0902 (alias qwen3.8-max-2026-09-02). QwenCloud says 0902 improves coding depth, multi-tool agent delivery, and visual understanding while keeping the 1M context, thinking mode, tools, and unchanged billing.

Microsoft AI

MAI-Image-2.6 is Microsoft AI's September 4, 2026 highest-precision image generation and editing model, in public preview on Microsoft Foundry and MAI Playground. Microsoft says it ranks No. 2 for text-to-image and image editing on Arena and Artificial Analysis as of September 4, with multi-image reference editing, web grounding, dynamic aspect ratios, and up to 1.5K resolution.
