EF 3.1 single score: 9.05 µPt

About 7 minutes of an average person's yearly footprint in these categories. 9 of 16 categories, 72% of the EF weight. Fossil resource use counts the fuel burnt for dutch electricity, not its supply chain; water scarcity uses the aware factor for the netherlands (0.957).

Claude, Fable 5.1 (measured)
anthropic/claude-fable-5.1 · NVIDIA H100 SXM5 80GB · 351 req · 2505936 in / 602877 out · batch 32 · bf16 · size inferred 93.0 B · grade F? at 1.3843 Wh per request
Measured from this Claude Code session's transcript (d6013ead): every claude-fable-5-1 request from 2026-10-02 20:32 to 2026-10-03 16:26 UTC, the hours from the first episode file to the last render. tokens_in is fresh input plus cache writes; 182,851,347 more were read from the prompt cache and are not modelled, which makes this low. The window also holds side work done in the same hours. This record overlaps the session's automatic TELOS record; do not add the two. Model size is not published, so it is inferred from its price.

Measured from the same transcript and window: every claude-opus-5-5 request. 232,236,586 more tokens were read from the prompt cache and are not modelled. Same overlap note as above. Model size is not published, so it is inferred from its price.

Characters measured from the render job (aegir_six_clocks_v1_job.json, 76 segments; ElevenLabs eleven_v3 for Ægir, multilingual v2 for the narrator). ElevenLabs publishes no energy figure; the factor is the order-of-magnitude assumption used in the 2026-09-20 podcast record: about 70 s of audio per 1,000 characters, generated 35 times faster than real time on a 700 W accelerator drawing 595 W, 1.1 facility overhead, 0.364 Wh per 1,000 characters.

Voice, test slices before the render
8904.0 character × 0.000364 Wh
Characters measured from the 13 test-slice files in accent_test (speed, model, voice and Norwegian-name tests, slices A to N). Same assumed factor. None of this audio is in the episode.

Outcome. One episode (44 min 39 s, English) and its chipped café article, topic 334, with 88 verification chips. Draft 1 to 5 of the article, the script, voice tests and the render. Not counted: the external review of draft 4 by GPT-5.6 Sol in ChatGPT (no usage figures available), and the later cuts to the audio, done locally with ffmpeg.
