Claude connectorCommunity

Daily scores for Claude and GPT models on one private, code-graded test suite, so you can see whether a model is scoring lower than its own…

View in Claude directory

Nerf Watch gives the same private, code-graded tests to nine Claude and GPT models every day: Claude models through Claude Code on a Claude Max plan, and GPT models through Codex on ChatGPT Pro. Each model is compared with its own recent baseline.

This connector reads the published results through two read-only tools. get_nerfwatch_scores returns each model's latest score, previous runs, change and baseline. get_nerfwatch_history returns one model's retained daily score history, oldest first.

Use it to answer questions such as "Has Opus 5.5 scored lower this week?" or "How has GPT-6.1 Sol's score moved since October 20?"

Limits: each model runs once a day, so a single day is noisy. Missing days are missing, not zero, and comparisons hold within one suite version. A lower score is a lower score on this suite, not proof that a provider changed a model. The tests themselves stay private.

No account or sign-in is needed, and the connector writes nothing. tokenusage.dev is independent and not affiliated with Anthropic or OpenAI.
