Qwen3.6-35B-A3B Tool
Alibaba's open-weight agentic-coding model (35B total / 3B active, Apache 2.0) with 262K native context extensible toward 1M tokens, hybrid Gated-DeltaNet + MoE attention, thinking preservation across turns, and built-in tool use. Downloadable and self-hostable on common open serving stacks.
OpenCode Zen (Ox Alpha free tier) Tool
OpenCode's Zen gateway serves 'Ox Alpha,' a free, unlimited, reasoning-mandatory coding model with a load-tested one-million-token context window and no authentication required. Measured at about one second to first token and 35-46 tokens per second. Independent forensics attribute it to the GLM family; the operator has not identified itself, so treat everything you send it as disclosed to an unknown party.
OpenAI Codex Security (Daybreak) Tool
An in-IDE plugin from OpenAI's Daybreak initiative that finds, validates, and fixes software vulnerabilities, plus an open-source remediation program run with Trail of Bits and HackerOne.
Kimi CLI Tool
Moonshot's Apache-2.0 terminal agent for driving Kimi models from the command line for coding and tool use. Open-source software (distinct from the K3 model weights, due July 27).
