Deepseek / Deepseek V4 Flash
proDescription
DeepSeek's fast, economical model and the surprise of the V4 series. Flash carries the same million-token context window as DeepSeek's flagship at a fraction of the size. DeepSeek says it matches the flagship's reasoning when given a larger thinking budget, trailing only on pure knowledge and the hardest agent work. Text only. Open weights under an MIT license.
Tencent / Hy3
lightDescription
Tencent’s open-weight reasoning model, built for agents rather than chat. Hy3 blends fast and slow thinking, switching between quick replies and deep reasoning, and Tencent tuned it hard for real production work: tool use, long agent loops, and search. It activates only a fraction of its parameters per token, so it is unusually cheap to run for its capability. Text only. Open weights, Apache 2.0.

Deepseek / Deepseek V4 Flash
proCoding Assistants and Agent Loops
DeepSeek tuned V4 specifically for agent products, including Claude Code, OpenClaw, and OpenCode, and reports gains in code generation and document creation. Built for responsiveness inside a loop, not one-off answers.
Flagship Reasoning
Three modes: non-think for speed, think high for accuracy, think max for difficult work. DeepSeek says maximum effort brings it level with its flagship on reasoning, given a larger thinking budget.
Million-Token Window
A full million tokens, identical to DeepSeek's flagship. Its hybrid attention makes that window cheap to serve. At maximum reasoning effort, DeepSeek recommends allowing at least 384,000 tokens for the thinking trace.
Document Creation at Speed
DeepSeek reports improvements in document creation alongside code. Suited to long contracts, manuals, and technical documentation where you want the whole thing read and rewritten quickly.
Knowledge, With Limits
DeepSeek is candid here: its smaller parameter count places it slightly behind the flagship on pure knowledge tasks. It also has no native web search, so current information has to come from you.
Text Only, No Image Input
Reads and writes text. No image, audio, or video input. Screenshots, diagrams, charts, and scanned pages are outside what this model can read, which rules it out for any visual work.
Tencent / Hy3
lightProduction Software Engineering
Tencent reports strong software development, front-end design, and even game production, refined through its own WorkBuddy and CodeBuddy products. It concedes repository-scale coding to the strongest open rival but performs well on real, shippable work.
Fast And Slow Thinking
A hybrid reasoning design with selectable effort: a no-think mode for quick replies, and deeper modes for hard problems. That lets you spend reasoning only where a task needs it, keeping simple steps fast and cheap.
Long-Context Retrieval
Holds a large context and is tuned to parse messy, lengthy input while following complex rules. Tencent reports it powering agent workflows of hundreds of steps without losing the thread.
Office And Productivity Work
Tencent highlights office productivity, financial modelling, and document generation, including PowerPoint creation through its Yuanbao product. Built for structured, real-world business output rather than long-form prose.
Agentic Search And Tool Use
Its standout strength. Tencent reports leading the open field on agentic search and tool orchestration, retrieving, filtering, and integrating information across sources. Works with agent frameworks like OpenClaw, OpenCode, and Cline.
Text Only Input
Reads and writes text. No image, audio, or video input. Despite the Hunyuan family including media models, Hy3 itself is a pure reasoning and agentic language model, so screenshots and diagrams are outside what it reads.
