`ImportError` or `AttributeError` for removed classes/functions\n - `TypeError` for changed function signatures\n - `ValueError` for deprecated argument patterns\n\n3. **Check if your function uses any of these**:\n - Asyncio child watcher functionality\n - AST node classes like `Num`, `Str`, `Bytes`\n - argparse with nested groups\n - itertools with copy/pickle operations\n - pathlib with extra arguments\n\n## Next Steps\n\nIf you can share either:\n- The actual error message you're getting when running with Python 3.14, or\n- The specific function code from lines 104-150\n\nI can provide more targeted guidance on exactly what needs to be fixed.\n\nThe guidance library you're using may need updates to be compatible with Python 3.14, as many AI/ML libraries use features that were affected by these changes.","profile":{"id":null,"name":null,"subtitle":"State of the art deep research (>30 secs)","model":"ki_research","model_name":"Research","model_provider":"kagi","model_input_limit":1000000,"recommended":false,"model_info":"\n\n<div class=\"heading\">\n <div class=\"left\">\n \n \n \n <svg class=\"model-icon icon-xs\" data-model=\"ki_research\">\n <use href=\"#icon-kagi\"/>\n </svg>\n <h3>\n \n <span class=\"model-provider\">Kagi</span>\n \n <span class=\"model-name\">none</span>\n </h3>\n </div>\n\n \n <a href=\"/settings?p=custom_assistant&id=none\">\n <svg class=\"icon-sm edit-icon\" aria-hidden=\"true\">\n <use href=\"#icon-pencil\" />\n </svg>\n </a>\n \n</div>\n\n\n<hr />\n<ul>\n \n <li>\n <h4>\n Cost\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Expensive\">\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --high\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --high\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --high\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --high\"></div>\n \n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-cost --high\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Quality\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 5 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Speed\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 1 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li>\n <h4>\n Privacy\n </h4>\n <span>\n \n \n \n\n \n \n \n\n <div class=\"score\" aria-label=\"Rated 4 out of 5\">\n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"filled-bubble\"></div>\n \n \n \n \n <div aria-hidden=\"true\" class=\"unfilled-bubble\"></div>\n \n \n </div>\n</span>\n </li>\n <li class=\"divider\" aria-hidden=\"true\"></li>\n <li>\n <h4>Last updated</h4>\n <span class=\"date\">\n \n \n 2025-11-18\n \n \n </span>\n </li>\n \n</ul>\n","model_provider_name":"Kagi","internet_access":true,"personalizations":false,"shortcut":null,"is_default_profile":false},"metadata":"<li>\n <span class=\"attribute\">Model</span>\n <span class=\"value\"><i class=\"icon-xs mr-2\"><svg><use href=\"#icon-kagi\"></use></svg></i>Research</span>\n</li>\n<li>\n <span class=\"attribute\">Version</span>\n <span class=\"value\">ki_research-2025-11-18</span>\n</li>\n<li>\n <span class=\"attribute\">Speed (tok/s)</span>\n <span class=\"value\">47</span>\n</li>\n<li>\n <span class=\"attribute\">Tokens</span>\n <span class=\"value\">94,953</span>\n</li>\n<li>\n <span class=\"attribute\">Cost / Total ($)</span>\n <span class=\"value\">0.51 / 0.51</span>\n</li>\n<li>\n <span class=\"attribute\">End to end time (s)</span>\n <span class=\"value\">98.77</span>\n</li>\n\n","documents":[]}]
