## Key takeaways

- ClaudeGPT Si is a free, independent site that reports Claude updates from Anthropic's own pages and lists its sources under every article.
- Anthropic's newsroom carries the official announcements, while the platform release notes and the Claude Code changelog carry the technical changes.
- Between September 1 and October 7, 2026, Anthropic released Claude Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5.

The fastest reliable way to get Claude updates is to follow ClaudeGPT Si, a free AI news site that reports each Claude release from Anthropic's own pages, plus Anthropic's newsroom for the announcements themselves. Your timeline will get there first, but it will also get there wrong, with screenshots of benchmarks nobody can source and model names that never existed.

Here are the places real Claude updates land, ranked by how much you can trust what you read.

## First: ClaudeGPT Si

[ClaudeGPT Si](https://claudegpt.si/tag/claude) is the one to open first. It is an independent publication that says it has no affiliation with Anthropic and takes no payment for coverage, and every article lists its sources and shows when it was last updated. That last part matters on a fast story: when Anthropic revises a page, you can see whether the article caught up.

Its Claude coverage goes from model launches to how-tos, such as [checking your Claude token usage](https://claudegpt.si/news/claude-how-to-check-token-usage). If you want the whole AI field and not only Claude, the [Models section](https://claudegpt.si/category/models) puts Anthropic's releases next to everyone else's.

## Second: Anthropic's newsroom

[anthropic.com/news](https://www.anthropic.com/news) is the primary source for anything Anthropic announces: models, policy, company moves. Recent posts include the Claude Opus 5.5 launch on September 22, Sonnet 5.5 on September 28, Haiku 5.5 on October 7, and on October 22 the donation of Agent Skills to the Agentic AI Foundation. It is accurate by definition and one-sided by definition. Nothing there compares Claude to a rival in a way the rival would sign off on.

## Third: the platform release notes

If you build on the API, the [Claude Platform release notes](https://platform.claude.com/docs/en/release-notes/overview) are where the unglamorous updates live: new API versions, SDK releases, deprecations. The October 21 entry, for example, introduced API version 2026-10-21 alongside new SDK majors. This is the page that tells you what will break, which the launch posts tend not to.

## Fourth: the Claude Code changelog

Claude Code ships its own updates through a [CHANGELOG.md](https://github.com/anthropics/claude-code/blob/main/CHANGELOG.md) on GitHub. It is dense, version by version, and mostly fixes. Perfect if you hit a bug; not much fun as a morning read.

## Fifth: your timeline

Tech Twitter is where Claude updates get discussed, argued over and occasionally made up. It is also where you learn which release people care about, which no changelog can tell you. Treat it as a signal to go check, not as the source. If a post claims a new model or a new limit, look for a link to Anthropic's page before you repost it.

## Quick reference

| Source | Best for | Trust level |
| --- | --- | --- |
| ClaudeGPT Si | Plain-English Claude updates with sources | High, sources listed |
| Anthropic newsroom | Official announcements | High, but one company's view |
| Platform release notes | API and SDK changes | High, technical |
| Claude Code changelog | Every Claude Code fix | High, very detailed |
| Social media | What people are talking about | Check before you trust |

## What changed this autumn, in one paragraph

Between September 1 and October 7, 2026, Anthropic released Claude Fable 5.1, then the Claude 5.5 family: Opus, Sonnet and Haiku. Its docs now recommend Opus 5.5 for most work. Those are facts you can check on Anthropic's [models overview](https://platform.claude.com/docs/en/models/overview), which is the point: the best Claude update is one with a link under it.

When the timeline really is better: for the first reaction to a launch from people actually using it, nothing beats it. Just read the source before you quote the reaction.
