Anthropic's current Opus model and its recommended starting point for most workloads as of October 2026, first of the Claude 5.5 family. Built for long-running agentic coding and knowledge work, with always-on adaptive thinking and a 1M-token context.
Most efficient GPT-6 model (September 2026) for focused, high-volume work, priced at $0.10 input and $0.50 output per million tokens, with the full 1.05M context and effort from none to max. OpenAI's suggested replacement for retiring GPT-4o and GPT-4.1 snapshots.
First Sol model of the GPT-6 generation (September 2026), built for complex coding and agentic workflows with a 1.05M context and none-to-max reasoning. Followed a week later by GPT-6.1 Sol, which replaced it in OpenAI's main lineup.
xAI's flagship model as of October 2026, released September 21, 2026 for coding, agents and knowledge work. Offers a 500k-token context, no text output limit and reasoning effort up to xhigh.
Now served by DeepSeek-V4.1-Flash (API name deepseek-flash), DeepSeek's newest model and cheaper tier since September 2026: an open-weight 552B MoE with a 1M context. It replaced the retired V4-Flash.
DeepSeek-V4.1-Flash (September 2026), the first model on DeepSeek's V4.1 architecture: it uses a 552B backbone activating 8B parameters in prefill and 16B in decode, and supports 1M tokens under MIT.
OpenAI's flagship as of October 2026, released September 2026 as the top GPT-6 model for demanding reasoning, coding, computer use and research. 1.05M-token context, 128K output, reasoning effort from low to max.
Google's current Flash model, GA since September 2026, aimed at long-horizon software engineering and autonomous agents. Reads text, image, video, audio and PDF in a 1M-token context, with 64K output and low, medium or high thinking.
Upgraded September 2, 2026 snapshot of Qwen3.8-Max (also named qwen3.8-max-2026-09-02) with better engineering-scale coding and multi-tool agent orchestration, keeping the 1M context. The newest Max build.
Anthropic's most capable generally available model as of October 2026, succeeding Claude Fable 5. A Mythos-class tier above Opus for demanding reasoning and long-horizon agentic work, with always-on adaptive thinking and a 1M-token context.
Current Qwen Flash tier (August 2026): a model with a 1M-token context for coding assistance and agent workflows, compatible with OpenAI and Anthropic API formats; Alibaba's low-cost recommendation.
GLM-5.3-Flash (August 2026), a newly trained Z.ai GLM-5 model: a 320B MoE with 18B active, hybrid sparse and linear attention and MIT weights, which Z.ai says beats GLM-5.2 at about a tenth of the price.
Z.ai's GLM-5.3 (August 2026), GLM-5.2's base with heavier post-training for coding and agentic work and a 1M-token context, served by Alibaba Cloud, Mistral and Together.
Qwen3.8 27B dense model (August 2026, open weights), improving on 3.6-27B in coding and office tasks; 1M context on Model Studio. The newest dense Qwen model.
The August 2026 general-availability release of DeepSeek-V4-Pro, a 1.6T-parameter MoE with 49B active and a 1M-token context, served by DeepInfra and Together with low, high and max reasoning effort.
Flash model released in August 2026, three weeks after 3.6 Flash, with coding and web-development gains and a March 2026 knowledge cutoff. Deprecated in October 2026; requests now route to its successor, Gemini 3.8 Flash.
August 2026 successor to Grok 4.5, tuned for long-running agents and interactive work, with a 500k-token context. Grok 4.7 replaced it as xAI's top model in September 2026 at the same token prices.
