| You can't downvote a post, so that's not a factor.

| Also it's not as powerful as you think. In the past I have
| spent a lot of time looking at /new, and upvoting stories
| that I think should be surfaced. The vast majority of them
| still never hit near the front page.
|
| It's a real shame, because some of the best and most
| relevant submissions don't seem to make it.

| digiown wrote:
| No I was wrong. You can't downvote posts. Flags are used

| This looks great. I've been using OpenWebUI for a while now and

|
| This looks like it's not only a better license, but also much
| better features.
| mythz wrote:
| Yep Open WebUI's switch to a non OSS license to inhibit
| competitive forks [1], in their own words [2] ensures I'll
| never use them. Happy to develop an OSS alternative that does
| the opposite whose rewrite on extensibility enables community
| extensions can replace built-in components and extensions so it
| can easily be rebranded and extended with custom UI + Server
| features.
|
| The goal is for the core main.py to be a single file without
| requiring additional dependencies, anything that does can be
| loaded as an extension (i.e. just a folder with .py server and
| UI hooks). There's also a script + docs so you can mix n' match
| the single main.py file and repackage it which whatever
| extensions you want included [3].

| Can this be used in a multi user scenario?
| mythz wrote:
| Yep, but it only supports GitHub OAuth. i.e. Content is either
| saved under no user (anonymous) or the authenticated GitHub
| User.

| Thanks. Looks like this is purely to gatekeep internal

| session store.
|
| All the best for the project, will check in later on these..

| mythz wrote:
| No custom state machine or agent, it's only a copy of
| Anthropic's 3 computer use tools: run_bash, edit, computer.

|
| It's run in the same process, there's no long agent loops,
| everything's encapsulated within a single message thread.

| What is ChatGPT used in the title when it's clearly a much more

| mythz wrote:
| Couldn't think of a better title, do you have any suggestions?

| Do people really use claude code or any other agent with a paid

| mythz wrote:
| I wouldn't use Claude API Key pricing, but I also wouldn't get
| a Claude Max sub unless it was the only AI tool I used.
|
| Antigravity / Google AI Pro is much better value, been using it
| as my primary IDE assistant for a couple months and have yet to
| hit a quota limit on my $16/mo sub (annual pricing) which also
| includes a tonne of other AI perks inc. Nano Banana, TTS,
| NotebookLM, storage, etc.
|
| No need to use Anthropic's premium models for tool calling when
| Gemini/MiniMax are better value models that still perform well.
|
| I still have a Claude Pro plan, but I use it much less than
| Antigravity and thanks to Anthropic axing their sub usage, I no
| longer use it outside of CC.
| esperent wrote:
| Counterpoint: on the $20 monthly account I would hit my 5

| short.

| Rate limits mostly - plus claude code is a relatively recent

| Curious about the MCP integration. Are people using this for
| production workloads or mostly experimentation?
| mythz wrote:
| MCP support is available via the fast_mcp extension:
| https://llmspy.org/docs/mcp/fast_mcp
|
| I use llms .py as a personal assistant and MCP is required to
| access tools available via MCP.
|
| MCP is a great way to make features available to AI assistants,
| here's a couple I've created after enabling MCP support:
|
| - https://llmspy.org/docs/mcp/gemini_gen_mcp - Give AI Agents
| ability to generate Nano Banana Images or generate TTS audio
|
| - https://llmspy.org/docs/mcp/omarchy_mcp - Manage Omarchy
| Desktop Themes with natural language
|
| I will say there's a noticable delay in using MCP vs tools,
| where I ended up porting Anthropic's node filesystem MCP to
| Python [1] to speed up common AI Assistant tasks, so their not
| ideal for frequent access of small tasks, but are great for
| long running tasks like Image/Audio generation.

| Does the MCP implementation make it easy to swap out the

| hit or miss for actual print-on-demand products compared to
| Midjourney. Since MJ still doesn't have a real API I've been
| routing requests to Flux via Replicate for higher quality
| automated flows. Curious if I could plug that in here without
| too much friction.
