Mehr aus diesem Repository langchain-deploy-integration Deploy a LangChain 1.0 / LangGraph 1.0 app to Cloud Run, Vercel, or LangServe correctly — with timeouts sized for chain length, cold-start mitigation, SSE anti-buffering headers, and Secret Manager over .env. Use when prepping a first production deploy, debugging a stream that hangs behind a proxy, or diagnosing p99 latency spikes. Trigger with "langchain deploy", "langchain cloud run", "langchain vercel python", "langchain langserve", or "langchain docker".
langchain-langgraph-agents Build a correct LangGraph 1.0 ReAct agent with create_react_agent — typed tools, error propagation, recursion caps, and stop conditions that actually stop. Use when writing a first tool-calling agent, migrating from AgentExecutor or initialize_agent, or diagnosing an agent that loops on vague prompts. Trigger with "langgraph agent", "create_react_agent", "langgraph tool calling", "AgentExecutor migration", or "agent loop cost".
langchain-langgraph-human-in-loop Build LangGraph 1.0 human-in-the-loop approval flows with interrupt_before /
interrupt_after and Command(resume=...) — JSON-serializable state, clean
resume semantics, and UI wiring for approval decisions. Use when adding an
approval gate before an expensive tool call, wiring a Slack/web UI for agent
approvals, or debugging a graph that crashes on interrupt.

Overview
Guide for migrating between Ideogram API versions. The primary migration path is from the legacy /generate endpoint (JSON body, V_1/V_2 models) to the V3 endpoints (multipart form data, new parameters). This covers breaking changes in request format, model names, aspect ratio syntax, style types, and new capabilities.
Breaking Changes: Legacy to V3
Aspect Legacy (/generate) V3 (/v1/ideogram-v3/generate) Content-Type application/jsonmultipart/form-dataBody format { "image_request": { ... } }FormData fields Models V_1, V_1_TURBO, V_2, V_2_TURBO, V_2AImplicit V3 (no model field) Aspect ratio ASPECT_16_916x9Style types AUTO, GENERAL, REALISTIC, DESIGN, RENDER_3D, ANIMEAUTO, GENERAL, REALISTIC, DESIGN, FICTIONMagic prompt magic_prompt_optionmagic_promptNew in V3 -- rendering_speed, style_preset, style_codes, character_reference_imagesColor palette Preset name or hex array Same, with weight support
Instructions
Step 1: Audit Current API Usage
set -euo pipefail
grep -rn "api.ideogram.ai"
"*.ts"
"*.js"
"*.py"
"ASPECT_"
"*.ts"
"*.js"
"image_request"
"*.ts"
"*.js"
"magic_prompt_option"
"*.ts"
"*.js"
Step 2: Create Adapter for Both Versions
interface GenerateOptions {
prompt : string ;
style ?: string ;
aspectRatio ?: string ;
negativePrompt ?: string ;
seed ?: number ;
renderingSpeed ?: string ;
stylePreset ?: string ;
}
const API_KEY = process.env .IDEOGRAM_API_KEY !;
const USE_V3 = process.env .IDEOGRAM_API_VERSION === "v3" ;
async function generateImage (options : GenerateOptions return USE_V3 ? generateV3 (options) : generateLegacy (options);
}
async function generateLegacy (options : GenerateOptions const response = await fetch ("https://api.ideogram.ai/generate" , {
method : "POST" ,
headers : { "Api-Key" : API_KEY , "Content-Type" : "application/json" },
body : JSON .stringify ({
image_request : {
prompt : options.prompt ,
model : "V_2" ,
style_type : options.style ?? "AUTO" ,
aspect_ratio : options.aspectRatio ?? "ASPECT_1_1" ,
magic_prompt_option : "AUTO" ,
negative_prompt : options.negativePrompt ,
seed : options.seed ,
},
}),
});
if (!response.ok ) throw new Error (`Legacy generate: ${response.status} ` );
return response.json ();
}
async function generateV3 (options : GenerateOptions const form = new FormData ();
form.append ("prompt" , options.prompt );
form.append ("style_type" , mapStyleToV3 (options.style ?? "AUTO" ));
form.append ("aspect_ratio" , mapAspectRatioToV3 (options.aspectRatio ?? "ASPECT_1_1" ));
form.append ("magic_prompt" , "AUTO" );
form.append ("rendering_speed" , options.renderingSpeed ?? "DEFAULT" );
if (options.negativePrompt ) form.append ("negative_prompt" , options.negativePrompt );
if (options.seed ) form.append ("seed" , String (options.seed ));
if (options.stylePreset ) form.append ("style_preset" , options.stylePreset );
const response = await fetch ("https://api.ideogram.ai/v1/ideogram-v3/generate" , {
method : "POST" ,
headers : { "Api-Key" : API_KEY },
body : form,
});
if (!response.ok ) throw new Error (`V3 generate: ${response.status} ` );
return response.json ();
}
Step 3: Map Legacy Enums to V3 function mapAspectRatioToV3 (legacy : string string {
const map : Record <string , string > = {
"ASPECT_1_1" : "1x1" , "ASPECT_16_9" : "16x9" , "ASPECT_9_16" : "9x16" ,
"ASPECT_3_2" : "3x2" , "ASPECT_2_3" : "2x3" , "ASPECT_4_3" : "4x3" ,
"ASPECT_3_4" : "3x4" , "ASPECT_10_16" : "10x16" , "ASPECT_16_10" : "16x10" ,
"ASPECT_1_3" : "1x3" , "ASPECT_3_1" : "3x1" ,
};
return map[legacy] ?? legacy;
}
function mapStyleToV3 (legacy : string string {
const map : Record <string , string > = {
"AUTO" : "AUTO" ,
"GENERAL" : "GENERAL" ,
"REALISTIC" : "REALISTIC" ,
"DESIGN" : "DESIGN" ,
"RENDER_3D" : "GENERAL" ,
"ANIME" : "FICTION" ,
};
return map[legacy] ?? "GENERAL" ;
}
Step 4: Feature Flag Rollout
function shouldUseV3 (userId ?: string boolean {
if (process.env .IDEOGRAM_FORCE_V3 === "true" ) return true ;
if (userId) {
const hash = Array .from (userId).reduce ((h, c ) => h * 31 + c.charCodeAt (0 ), 0 );
const percentage = parseInt (process.env .IDEOGRAM_V3_PERCENTAGE ?? "0" );
return (Math .abs (hash) % 100 ) < percentage;
}
return false ;
}
Step 5: Validate Migration
async function validateMigration (prompt : string const [legacy, v3] = await Promise .all ([
generateLegacy ({ prompt, style : "REALISTIC" , aspectRatio : "ASPECT_16_9" }),
generateV3 ({ prompt, style : "REALISTIC" , aspectRatio : "ASPECT_16_9" }),
]);
console .log ("Legacy:" , { resolution : legacy.data [0 ].resolution , seed : legacy.data [0 ].seed });
console .log ("V3:" , { resolution : v3.data [0 ].resolution , seed : v3.data [0 ].seed });
console .log ("Both returned images:" , legacy.data .length > 0 && v3.data .length > 0 );
}
V3 Exclusive Features After migration, you gain access to:
Rendering speed : FLASH, TURBO, DEFAULT, QUALITY50+ style presets : OIL_PAINTING, WATERCOLOR, POP_ART, JAPANDI_FUSION, etc.Style codes : 8-char hex codes for precise style matchingCharacter reference images : Consistent character faces across generationsStyle reference images : Upload style examplesColor palettes with weights : Fine-grained color control
Error Handling Issue Cause Solution RENDER_3D fails in V3Removed from V3 style types Map to GENERAL ANIME fails in V3Renamed to FICTION Update enum mapping JSON body rejected by V3 V3 requires multipart form Switch to FormData magic_prompt_option ignoredV3 uses magic_prompt Update field name model field in V3V3 has no model field Remove from V3 requests
Output
Adapter supporting both legacy and V3 endpoints
Enum mapping functions for breaking changes
Feature flag for gradual rollout
Validation script comparing both endpoints
