Ok for image generation, I recommend flux 2 klein 4b and run it with stable diffusion which provides both a cli and a web UI. You can also run it through comfyui instead, but after trying it out I wasn't a massive fan.
For the rest I'm confused, you said no to agentic and coding, but then mentioned task logging and summarising documents, which depending on the tasks and documents, can benefit from agentic and coding? You won't be running a sota model, so the llm won't know everything. It will need to be honest about what it does and doesn't know, and be able to research using the internet, then if you want it to produce a document in a folder summarising or reporting for you, this is all agentic stuff, you need to setup MCP tooling.
Genuinely if you want a good general chat bot that can use the internet, if go with lfm2.5 8b a1b on a q4 k m as it will be really fast and good quality. If you want something stronger with the agentic tool calling then orinth 1.5 35b a3b q4 k m.
