From 4e21ddc8d85f679470b57760114938c175c6e14d Mon Sep 17 00:00:00 2001 From: Classic298 <27028174+Classic298@users.noreply.github.com> Date: Tue, 3 Nov 2026 19:43:34 +0100 Subject: [PATCH] feat: set the chat read limit from the admin settings The limit on how much of an earlier chat a model can read could only be set with an environment variable. It is now a Chat Read Limit field in Admin Settings under General, next to the skill limits. The environment variable still works as the starting value, and the setting saved in the panel takes precedence. --- backend/open_webui/config.py | 5 +++++ backend/open_webui/env.py | 2 -- backend/open_webui/routers/auths.py | 4 ++++ backend/open_webui/tools/builtin.py | 6 +++--- src/lib/components/admin/Settings/General.svelte | 16 ++++++++++++++++ src/lib/i18n/locales/en-US/translation.json | 2 ++ 6 files changed, 30 insertions(+), 5 deletions(-) diff --git a/backend/open_webui/config.py b/backend/open_webui/config.py index 3e98856ec4..b934887edd 100644 --- a/backend/open_webui/config.py +++ b/backend/open_webui/config.py @@ -2067,6 +2067,10 @@ SKILL_PREVIEW_MAX_CHARS = int(os.environ['SKILL_PREVIEW_MAX_CHARS']) if os.geten if SKILL_PREVIEW_MAX_CHARS is not None and SKILL_PREVIEW_MAX_CHARS <= 0: raise ValueError('SKILL_PREVIEW_MAX_CHARS must be a positive integer or unset') +VIEW_CHAT_MAX_CHARS = int(os.environ['VIEW_CHAT_MAX_CHARS']) if os.getenv('VIEW_CHAT_MAX_CHARS') else None +if VIEW_CHAT_MAX_CHARS is not None and VIEW_CHAT_MAX_CHARS <= 0: + raise ValueError('VIEW_CHAT_MAX_CHARS must be a positive integer or unset') + ENABLE_CHANNELS = os.getenv('ENABLE_CHANNELS', 'False').lower() == 'true' ENABLE_ENCRYPTED_CHANNELS = os.getenv('ENABLE_ENCRYPTED_CHANNELS', 'False').lower() == 'true' @@ -2929,6 +2933,7 @@ DEFAULT_CONFIG = { 'skills.lazy_loading.enable': ENABLE_SKILL_LAZY_LOADING, 'skills.content_max_chars': SKILL_CONTENT_MAX_CHARS, 'skills.preview_max_chars': SKILL_PREVIEW_MAX_CHARS, + 'chats.view_max_chars': VIEW_CHAT_MAX_CHARS, 'direct.enable': ENABLE_DIRECT_CONNECTIONS, 'direct.integrations.enable': ENABLE_DIRECT_INTEGRATIONS, 'ollama.enable': ENABLE_OLLAMA_API, diff --git a/backend/open_webui/env.py b/backend/open_webui/env.py index cdcbec7a66..b672fe0483 100644 --- a/backend/open_webui/env.py +++ b/backend/open_webui/env.py @@ -1176,8 +1176,6 @@ KNOWLEDGE_GREP_MAX_MATCHES = _int_env('KNOWLEDGE_GREP_MAX_MATCHES', 50) # Characters returned by view_file / view_knowledge_file.
