I analyzed the sentiment of every tweet I’ve posted about OpenAI and Anthropic.

I had Codex score ~4,000 company mentions from 0-10, where 0 is extremely negative and 10 is extremely positive.

Average scores: OpenAI: 4.89 Anthropic: 6.63

For Anthropic, my most negative stretch was between Claude 4 and Claude 4.1. There’s a clear uptick around Opus 4.5, then a slight uplift by Mythos and then massive crash with Opus 4.7.

For OpenAI, sentiment starts sliding hard from GPT-5 through GPT-5.3, probably because of the token-maxxing era. There’s also a sharp crash right before GPT-5.4, likely the supply-chain-risk backstabbing episode.

GPT-5.5 looks like the most positive OpenAI launch in the dataset so far.

Sentiment

Many users praised analyses ranking Anthropic higher than OpenAI for crediting better communication and expectation management, while others dismissed the comparisons as astrology-like or insulted the poster.

With the current slope of my sentiment since the launch of GPT-5.3-Codex, I will turn more bullish on OpenAI than Anthropic on September 30, 2026

(incredibly realistic forecast)

if you are not doing technical analysis on your own sentiment then what are you even doing

@scaling01 Can you plot the relative ratio between them over time

@scaling01 Anthropic consistently scores higher in sentiment across launches

The crashes during key releases suggest that user expectations are tightly linked to performance promises, and when those aren't met, sentiment drops sharply

@scaling01 scored every single mention but the real metric is how often u typed each one

6.63 for anthropic is generous tbh

@scaling01 What happened in that Claude 3→4 stretch that tanked your score? gap between 4.8 and 6.63 is wild most people don't quantify their ai bias, you actually did.

@scaling01 the ratio has been compressing since codex launched but "september 30" is doing a lot of heavy lifting for a metric that swings 0.2x on a single release cycle

@scaling01 你让 Codex 去给 OpenAI 和 Anthropic 的提及打分，这本身就有点东西。

相当于请 OpenAI 自家的模型来当裁判，结果 OpenAI 才 4.89，比 Anthropic 还低了 1.7 分。

连自家模型都没把自家公司捞起来，那说明你那批推文是真的负面，不是打分偏了。

@scaling01 kinda wild that an honest sentiment breakdown puts them that far apart.

what were the Anthropic low points about?

@scaling01 Anthropic scoring higher in your own writing says as much about how each company communicates as it does about the models. Anthropic has been better at managing expectations.

@scaling01 You do know there's this thing called grass; it's quite pleasant to sit in.
