Gap
The xAI model grok-4.20-multi-agent-0309 (the primary/canonical model ID) is missing from packages/proxy/schema/model_list.json. The catalog has the beta alias grok-4.20-multi-agent-beta-0309 but not the primary non-beta ID — which is how xAI now lists this model on their official docs. This follows the pattern of other grok-4.20 models in the catalog where both beta and non-beta IDs have separate entries (e.g., grok-4.20-beta-0309-reasoning and grok-4.20-0309-reasoning both exist).
Official sources
Verified fields
- Model ID:
grok-4.20-multi-agent-0309 — confirmed as the primary identifier on both pages
- Aliases:
grok-4.20-multi-agent, grok-4.20-multi-agent-latest, grok-4.20-multi-agent-beta-latest, grok-4.20-multi-agent-experimental-beta-0304, grok-4.20-multi-agent-experimental-beta-latest, grok-4.20-multi-agent-beta-0309 — all confirmed on model detail page
- Format:
openai — xAI uses OpenAI-compatible API format (same as all other grok models in catalog)
- Flavor:
chat
- Multimodal:
true — text and image input → text output (confirmed on model detail page)
- Input cost:
$1.25 / 1M tokens — confirmed on both models page and model detail page
- Output cost:
$2.50 / 1M tokens — confirmed on both pages
- Cached input cost:
$0.20 / 1M tokens — confirmed on model detail page
- Reasoning:
true — listed as a capability on model detail page
- Context window (max_input_tokens):
1000000 — confirmed on model detail page (1,000,000 tokens)
- Available providers:
["xAI"]
Fields NOT published
- max_output_tokens: Not specified on model detail page. Should be omitted or left for manual review.
- displayName: Not officially published; suggest
"Grok 4.20 Multi-Agent (0309)" based on naming pattern.
Comparison with existing catalog entry
The catalog has grok-4.20-multi-agent-beta-0309 with pricing $2.00/$6.00, which differs from the xAI official pricing of $1.25/$2.50. The beta entry may also need a pricing update, but that is a separate issue (cost update, not missing model).
Local files inspected
packages/proxy/schema/model_list.json — grep for grok-4.20-multi returns only grok-4.20-multi-agent-beta-0309- Existing pattern: the catalog has both
grok-4.20-beta-0309-non-reasoning AND grok-4.20-0309-non-reasoning as separate entries, confirming the convention of listing both beta and non-beta IDs
Verification notes
- Cross-source: Model ID confirmed on (1) xAI models listing page and (2) xAI model detail page — two independent official signals
- Recent commits:
grok-4.20-multi-agent-0309 not present in current model_list.json
- ID format:
grok-4.20-multi-agent-0309 matches xAI convention (like grok-4.20-0309-reasoning, grok-4.20-0309-non-reasoning)
- No duplicate issue: No existing

}Summary: Add grok-4.20-multi-agent-0309 to the xAI section of the model catalog. All fields except max_output_tokens are verified from official sources. The existing grok-4.20-multi-agent-beta-0309 entry may also need a pricing update ($2/$6 → $1.25/$2.50) as a separate issue.
