[GUI Plugin] Chapter Summarizer — Flash and detailed AI summaries, ready to use

[Wiggo]

I don’t have that many series that are still running where I can’t remember the plot. From that point of view, the $10 will last a long time.

Do you plan to add Anthropic as a provider?

I'd be more willing to add them as a provider if they would kindly grant me a development quota allowance as a sponsorship...

I'm not sure what all that means but I take it to be no

I never tried Anthropic API access directly, but at some point I may be interested.

I can't test it, but you may try this:

- select calibre's built-in OpenAI compatible provider
- API URL: https://api.anthropic.com/v1
- API key field: leave it blank
- HTTP headers:
x-api-key: <your-anthropic-key>
anthropic-version: 2023-06-01
- Model: e.g. claude-opus-4-... / claude-sonnet-4-... (try Refresh models or type it manually).

Version 1.3.2

- When appending to comments or custom column, omit run information

I configured the plugin as you advised but the summarization failed with an error message about the 'temperature' ...

Spoiler:

calibre, version 9.9.0
ERROR: Summarization failed: `temperature` is deprecated for this model.

Traceback (most recent call last):

ValueError: `temperature` is deprecated for this model.

What should I do about the 'temperature'? Set it to zero?

calibre's OpenAI-compatible current backend hardcodes temperature into every request.

Anthropic deprecated temperature on its newer models. Per the Effort docs, temperature was replaced by the effort parameter (sent as output_config.effort) on the current generation.

So I suggest you try older models that might still take the Temperature parameter, such as:

claude-haiku-4-5
claude-sonnet-4-5

edit: the attached test version provides an option on plugin's main config dialog to Enable Anthropic compatibility. It reuses calibre’s OpenAI-compatible request/stream parsing, but omits temperature.

It worked with Sonnet 4.5 but was a waste of $0.51 because the output was in Spanish. The source language is English, and output language is set to keep source language

(Edit: I just realized you attached an updated plugin; I used the previous version.)

Oh noes, I wouldn't use Sonnet for such simple task. Haiku neither, actually. Use free models... Regarding the language drift: see if you can repro the issue with Openrouter, Nvidia Free, or the Server B zero-config.

The models I suggested above were more targeted at the API compatibility test.

Yep. But I really don't recommend using frontier models on simple task!

I'd used Zero-config when I first tested the plugin and the output was in English then. Maybe the problem is specific to Claude?

Back when I tried the Ask AI plugin, I was successful with a free Google AI API key. I did get an Openrouter account but couldn't get the key to work.

I tried the Google key with the summarizer but I got an error message (something to do with surpassing the limit; I can't remember exact wording). Anyway, I didn't want the hassle of trying other free providers, and I don't have a problem paying for the API access via Claude as it's my primary AI provider.

I'll try the updated plugin to see if the language issue resolves.

Not a problem with Claude. Remember we're using a patch over a compatible backend

I wouldn't waste time with Google free, it's there just to bug users into paying for premium plans. The plugin offers the most accessible free options: Nvidia, for instance. But needs an API key, so user must get it.

Openrouter requires relaxed privacy permissions to expand free model availability:

I was able to get NVIDIA to work, but my attempt with Openrouter timed out. And I'm having output language issues with every attempt (except when I first tried with Zero-Config). I sent you a message with more details.
