update-llm-model-list
DevelopmentAudit and update the supported LLM model list in assets.py against litellm's registry (models.litellm.ai). Use when adding new models, pruning outdated ones, or verifying the list is correct.

Update LLM Model List
Overview
The canonical model list lives in sdks/python/agenta/sdk/utils/assets.py → supported_llm_models.
It drives the model dropdown in the playground, cost metadata, and the model_to_provider_mapping.
The authoritative external source is litellm.model_cost (2 600+ entries), which mirrors
https://models.litellm.ai/.
A pytest guard lives at:
sdks/python/oss/tests/pytest/unit/test_supported_llm_models.py
Key rules
- Every model must exist in
litellm.model_cost(direct key, or with provider prefix stripped).anthropic/claude-*→ litellm stores asclaude-*(prefix is intentional for routing, stripped for cost lookup)cohere/command-*→ litellm stores ascommand-*- All other providers keep their full prefix (e.g.
gemini/,groq/,together_ai/)
- Provider key (
"anthropic","gemini", …) must match the Secrets API enum inapi/oss/src/core/secrets/enums.py(StandardProviderKind). - No duplicates within a provider list.
Step 1 — Check which current models are outdated / wrong
Run this with uvx (no local install needed):
cat > /tmp/check_agenta_models.py << 'SCRIPT'
# /// script
# requires-python = ">=3.11"
# dependencies = ["litellm"]
# ///
import litellm, sys
# paste supported_llm_models here or import it
from agenta.sdk.utils.assets import supported_llm_models
mc = set(litellm.model_cost.keys())
def exists(m):
if m in mc: return True
if "/" in m and m.split("/", 1)[1] in mc: return True
return False
fails = []
for provider, models in supported_llm_models.items():
for model in models:
if not exists(model):
fails.append((provider, model))
total = sum(len(v) for v in supported_llm_models.values())
print(f"Total models checked: {total}")
if fails:
for p, m in fails:
print(f" MISSING [{p}] {m}")
sys.exit(1)
else:
print("All models valid ✓")
SCRIPT
uvx --with litellm python /tmp/check_agenta_models.py 2>/dev/null
Alternatively, run the pytest unit test directly (requires agenta installed):
pytest sdks/python/oss/tests/pytest/unit/test_supported_llm_models.py -v
Step 2 — Find models missing from Agenta (big-3 audit)
This script finds models in litellm that Agenta doesn't list yet, filtered to remove noise (audio, video, embeddings, codex, snapshots):
cat > /tmp/find_missing.py << 'SCRIPT'
# /// script
# requires-python = ">=3.11"
# dependencies = ["litellm"]
# ///
import litellm, re
AGENTA_ANTHROPIC = set() # fill from assets.py (bare names, no prefix)
AGENTA_OPENAI = set() # fill from assets.py
AGENTA_GEMINI = set() # fill from assets.py (with gemini/ prefix)
mc = set(litellm.model_cost.keys())
NOISE = [
"audio","tts","speech","whisper","transcri","realtime","diarize",
"dall-e","image","video","veo","embed","moderat","search",
"babbage","davinci","ada","instruct","codex","computer-use",
"robotics","learnlm","gemma","live","v1:0",
]
KEEP = {"gpt-4o","gpt-4o-mini"}
DATED = re.compile(r"-\d{4}-\d{2}-\d{2}quot;)
EXP = re.compile(r"exp-\d{4}|\d{2}-\d{2}quot;)
def noise(m):
if m in KEEP: return False
return any(kw in m.lower() for kw in NOISE)
def dated(m):
return bool(DATED.search(m)) or bool(EXP.search(m))
def report(label, candidates, known, prefix=""):
print(f"\n=== {label} ===")
for m in sorted(candidates):
bare = m[len(prefix):] if prefix else m
if bare in known or m in known: continue
tag = "[dated/exp]" if dated(m) else "[alias]" if m.endswith("-latest") else "*** MISSING ***"
print(f" {m} {tag}")
# Anthropic
report("ANTHROPIC", [m for m in mc if m.startswith("claude-") and not noise(m)],
AGENTA_ANTHROPIC)
# OpenAI (no slash, starts with gpt- / o1 / o3 / o4)
OAI = [m for m in mc if any(m.startswith(p) for p in ("gpt-","o1","o3","o4","chatgpt"))
and "/" not in m and not noise(m)]
report("OPENAI", OAI, AGENTA_OPENAI)
# Gemini
report("GEMINI", [m for m in mc if m.startswith("gemini/") and not noise(m)],
AGENTA_GEMINI, prefix="gemini/")
SCRIPT
uvx --with litellm python /tmp/find_missing.py 2>/dev/null
Fill in the AGENTA_* sets from the current assets.py before running.
Step 3 — Edit assets.py
File: sdks/python/agenta/sdk/utils/assets.py
- Add models inside the correct provider list, newest first.
- For Gemini 1.5 models (still widely used): add under
"gemini". - For OpenAI o-series pro tiers (
o1-pro,o3-pro): add after their base model. - For Groq: always cross-check
litellm.groq_models— Groq rotates its model catalogue frequently. - For DeepInfra / Together AI: check
litellm.deepinfra_models/litellm.together_ai_modelsfor current names.
Provider prefix conventions
| Provider key | Agenta prefix | litellm cost key prefix |
|---|---|---|
anthropic | anthropic/ | claude- (no prefix) |
cohere | cohere/ | command- (no prefix) |
gemini | gemini/ | gemini/ |
groq | groq/ | groq/ |
mistral | mistral/ | mistral/ |
openai | (none) | (none) |
openrouter | openrouter/ | openrouter/ |
perplexityai | perplexity/ | perplexity/ |
together_ai | together_ai/ | together_ai/ |
deepinfra | deepinfra/ | deepinfra/ |
Step 4 — Run ruff then the test
# Format + lint
uvx --from ruff==0.14.0 ruff format sdks/python/agenta/sdk/utils/assets.py
uvx --from ruff==0.14.0 ruff check --fix sdks/python/agenta/sdk/utils/assets.py
# Validate all models against litellm (no agenta install needed)
uvx --with litellm python /tmp/check_agenta_models.py 2>/dev/null
All checks must pass before committing.
