Model catalog

Living map of model string → emission class used by carbonmd-factors-2026-08.

This page is steered weekly (Sunday evening, Europe/Zurich): new public releases and models seen in agent usage are classified, documented here, and wired into src/core/factors.ts.

Last steered: undefined-undefined-undefined Factors version: carbonmd-factors-2026-08

How to read this

Classes feed the gCO₂e bands in Methodology & factors.
Matching is heuristic and honest — unknown strings fall to medium + guessed: true.
Small markers win first (mini, flash, luna…), so tiered families classify correctly.

Frontier

High-capability flagships. Central undefined.undefined gCO₂e / undefinedk output tokens.

Family	Example IDs
OpenAI	`gpt-5.5`, `gpt-5.6-sol`, `o3`, `o4`
Anthropic	`claude-opus-5`, `claude-fable-5`, `mythos`
Google	`gemini-3.1-pro-preview`, `ultra`

Large

Workhorse coding / agent models. Central undefined.undefined gCO₂e / undefinedk output tokens.

Family	Example IDs
OpenAI	`gpt-5.6-terra`, `gpt-4o`, `codex`
Anthropic	`claude-sonnet-5`, `sonnet`
xAI	`grok-4.3`, `grok-4.5`, `grok-4*`
Moonshot	`kimi-k2.6`, `kimi-k2.7-code`, `kimi-k3`, `kimi-for-coding`
DeepSeek	`deepseek-v4-pro`, `deepseek/deepseek-v4-pro`
Alibaba	`qwen/qwen3.7-max`, `qwen3*`
Zhipu	`z-ai/glm-5.2`, `glm-5*`
Meta	`muse`, `muse-spark`
Other	`mistral-large`, `command`, `405b`, `r1`

Small

Cheap / fast tiers. Central undefined.undefined gCO₂e / undefinedk output tokens.

Family	Example IDs
OpenAI	`gpt-5.6-luna`, `gpt-5.4-mini`, `-mini`, `-nano`
Google	`gemini-3.5-flash`, `gemini-3.6-flash`, `-flash-lite`
DeepSeek	`deepseek-v4-flash`, `deepseek/deepseek-v4-flash`
xAI	`grok-composer-2.5-fast`
Markers	`haiku`, `flash`, `lite`, `micro`, `gemma`, `phi`, `1b`…`14b`

Medium (guessed)

Anything without a known marker. Central status.undefined gCO₂e / undefinedk output tokens, range widened in status.

If your production model lands here, open an issue or wait for the weekly steer.

Weekly steer

Every Sunday undefined:undefined Europe/Zurich, Hermes:

Scans public release notes + Hermes session_model_usage for new model IDs
Proposes class mappings (frontier / large / medium / small)
Updates factors.ts + this page + methodology examples
Rebuilds and deploys docs.carbonmd.dev ↗
Reports what changed

No silent factor-band rewrites: class values (gCO₂e table) only change with an explicit factors version bump and human review.
